I think actually close()ing the Connection when it appears to be broken rather than waiting for users to close() it themselves is overly aggressive, so I'm commenting the old behavior out. The only potential downside to this approach is that users who do not close() in a finally clause properly might see their close()es skipped by exceptions that previously would have led to automatic close(). But relying on the automatic close() was never reliable (since it only ever happened when c3p0 determined a Connection to be absolutely broken), and is generally speaking a client error that c3p0 ought not be responsible for dealing with.

* *

Parameter rootCauseOutParamHolder is an optional parameter, which if supplied, will be a Throwable array whose size * it at least one.

Allows one to work with the unproxied, raw Connection. Some * database companies never got over the "common interfaces mean * no more vendor lock-in!" thing, and offer non-standard API * on their Connections. This method permits you to "pierce" the * connection-pooling layer to call non-standard methods on the * original Connection, or to pass the original Connections to * functions that are not implementation neutral.

* *

To use this functionality, you'll need to cast a Connection * retrieved from a c3p0 PooledDataSource to a * C3P0ProxyConnection.

* *

This method works by making a reflective call of method m on * Object target (which may be null for static methods), passing * and argument list args. For the method target, or for any argument, * you may substitute the special token C3P0ProxyConnection.RAW_CONNECTION

* *

Any Statements or ResultSets returned by the operation will be proxied * and c3p0-managed, meaning that these resources will be automatically closed * if the user does not close them first when this Connection is checked back * into the pool. Any other resources returned by the operation are the user's * responsibility to clean up!

* *

If C3P0Registry maintains hard references to * DataSources, then they can never be garbage collected. But if c3p0 retains only * weak references, then applications that look up DataSources, then dereference them, * and then re-look them up again (not a great idea, but not uncommon) might see * distinct DataSources over multiple lookups. * * C3P0 resolves this issue has followed: At first creation or lookup of a PooledDataSource, * c3p0 creates a hard reference to that DataSource. So long as the DataSource has not * been close()ed or DataSources.destroy()ed, subsequent lookups will consistently * return the same DataSource. If the DataSource is never closed, then there is a potential * memory leak (as well as the potential Thread leak and Connection leak). But if * the DataSource is close()ed, only weak refernces to the DataSource will be retained. * A lookup of a DataSource after it has been close()ed within the current VM may * return the previously close()ed instance, or may return a fresh instance, depending * on whether the weak reference has been cleared. In other words, the result of * looking up a DataSource after having close()ed it in the current VM is undefined. * * Note that unpooled c3p0 DataSources are always held by weak references, since * they are never explicitly close()ed. The result of looking up an unpooled DataSource, * modifying it, dereferencing it, and then relooking up is therefore undefined as well. * * These issues are mostly academic. Under normal use scenarios, how c3p0 deals with * maintaining its registry doesn't much matter. In the past, c3p0 maintained hard * references to DataSources indefinitely. At least one user ran into side effects * of the unwanted retention of old DataSources (in a process left to run for months * at a time, and frequently reconstructing multiple DataSources), so now we take care * to ensure that when users properly close() and dereference DataSources, they can * indeed be garbage collected. */ public final class C3P0Registry { private final static String MC_PARAM = "com.mchange.v2.c3p0.management.ManagementCoordinator"; //MT: thread-safe final static MLogger logger = MLog.getLogger( C3P0Registry.class ); //MT: protected by class' lock static boolean banner_printed = false; //MT: protected by class' lock static boolean registry_mbean_registered = false; //MT: thread-safe, immutable private static CoalesceChecker CC = IdentityTokenizedCoalesceChecker.INSTANCE; //MT: protected by class' lock //a weak, unsynchronized coalescer private static Coalescer idtCoalescer = CoalescerFactory.createCoalescer(CC, true , false); //MT: protected by class' lock private static Map tokensToTokenized = new DoubleWeakHashMap(); //MT: protected by class' lock private static HashSet unclosedPooledDataSources = new HashSet(); //MT: protected by its own lock private static Map classNamesToConnectionTesters = Collections.synchronizedMap( new HashMap() ); //MT: protected by its own lock private static Map classNamesToConnectionCustomizers = Collections.synchronizedMap( new HashMap() ); private static ManagementCoordinator mc; static { classNamesToConnectionTesters.put(C3P0Defaults.connectionTesterClassName(), C3P0Defaults.connectionTester()); String userManagementCoordinator = C3P0ConfigUtils.getPropFileConfigProperty(MC_PARAM); if (userManagementCoordinator != null) { try { mc = (ManagementCoordinator) Class.forName(userManagementCoordinator).newInstance(); } catch (Exception e) { if (logger.isLoggable(MLevel.WARNING)) logger.log(MLevel.WARNING, "Could not instantiate user-specified ManagementCoordinator " + userManagementCoordinator + ".

Encapsulates all the configuration information required by a c3p0 pooled DataSource.

* *

Newly constructed PoolConfig objects are preset with default values, * which you can define yourself (see below), * or you can rely on c3p0's built-in defaults. Just create a PoolConfig object, and change only the * properties you care about. Then pass it to the {@link com.mchange.v2.c3p0.DataSources#pooledDataSource(javax.sql.DataSource, com.mchange.v2.c3p0.PoolConfig)} * method, and you're off!

* *

For those interested in the details, configuration properties can be specified in several ways:

*
    *
  1. Any property can be set explicitly by calling the corresponding method on a PoolConfig object.
    2. *
  2. Any property will default to a value defined by a System Property, using the property name shown the table below.
    3. *
  3. Any property not set in either of the above ways will default to a value found in a user-supplied Java properties file, * which may be placed in the resource path of * the ClassLoader that loaded the c3p0 libraries under the name /c3p0.properties.
    4. *
  4. Any property not set in any of the above ways will be defined according c3p0's built-in defaults.
    5. *
* *

Please see c3p0's main documentation for a description of all available parameters.

Most clients need never use or know about this interface -- c3p0 pooled DataSources * can be treated like any other DataSource.

* *

The functionality in this interface will be only be of interest if 1) for administrative * reasons you like to keep close track of the number and status of all Connections your application * is using; 2) to work around problems encountered while managing a DataSource whose clients are * poorly coded applications that leak Connections, but which you are not permitted to fix; * or 3) to work around problems that may occur if an underlying jdbc driver / DBMS system is * unreliable. In the third case, most users will be better off not using the present interface * at all, and using the DataSources' maxIdleTime, idleConnectionTestPeriod, * or testConnectionOnCheckout parameters to help your DataSources "automatically" heal. * But for those who prefer a more direct, manual approach, this interface is for you. It is anticipated * that the methods of this interface will primarily be of use to administrators managing c3p0 * PooledDataSources via JMX MBeans.

* *

Method Names & Per-User Pools

 * *

To understand this interface, you need to realize that a c3p0 PooledDataSource may represent * not just one pool of Connections, but many, if users call the method * Connection getConnection(String username, String password) rather than the * no-argument getConnection() method. If users make use of non-default username, password * combinations, there will be a separate pool for each set of authentification criteria supplied.

* *

Many methods in this interface have three variants:

*
    *
  1. <method-name>DefaultUser()
    2. *
  2. <method-name>(String username, String password)
    3. *
  3. <method-name>AllUsers()
    4. *
*

The first variant makes use of the pool maintained for the default user -- * Connections created by calls to the no argument getConnection(), * the second variant lets you keeps track of pools created by calling * getConnection( username, password ), and the third variant * provides aggregate information or performs operation on all pools.

* *

Under most circumstances, non-default authentication credentials will not * be used, and methods of the first variant are sufficient to manage the DataSource.

* *

Soft and Hard Resets

* *

A properly configured PooledDataSource whose applications are careful to close all checked-out Connections * would never need to use these methods. But, sometimes applications are untrustworthy * and leak Connections, or database administrators suspect that Connections may be corrupt or invalid, * and would like to force a pool to flush and acquire fresh Connections. This interface provides two * ways to do so.

* *
    *
  1. hardReset() immediately closes all Connections managed by the DataSource, including * those that are currently checked out, bringing the DataSource back to the state it was in before * the first client called getConnection(). This method is obviously disruptive, and should be with * great care. Administrators who need to work around client applications that leak Connections, can * periodically poll for pool exhaustion (using the methods of this class, or by attempting to retrieve * a Connection and timing out) and use this method clean-up all Connections and start over. But calling * this method risks breaking Connections in current use by valid applications.

    2. * *
  2. softResetDefaultUser(), softReset( username, password ) and * softResetAllUsers() asks the DataSource to flush its current pool of Connections and * reacquire without invalidating currently checked-out Connections. Currently checked out Connections * are logically removed from the pool, but their destruction is deferred until a client attempts to close() / check-in * the Connection. Administrators who suspect that some Connections in the pool may be invalid, but who do not * wish to rely upon c3p0's automatic testing and detection mechanisms to resolve the problem, may call these * methods to force a refresh without disrupting current clients. Administrators who suspect that clients may be * leaking Connections may minimize disruptive hardReset() calls by using softReset() until the number of unclosed * orphaned connections reaches an unacceptable level. (See above to understand * why there are three variants of this method.)
    3. *
* *

Understanding Connection Counts

* *

For each per-user pool, four different statistics are available:

* *
    *
  1. numConnections represents the total number of Connections in the pool.

    2. *
  2. numIdleConnections represents the number of Connections in the pool that are currently available for checkout.

    3. *
  3. numBusyConnections represents the number of Connections in the pool that are currently checked out. The * invariant numIdleConnections + numBusyConnections == numConnections should always hold.

    4. *
  4. numUnclosedOrphanedConnections will only be non-zero following a call to softReset(). It represents * the number of Connections that were checked out when a soft reset occurred and were therefore * silently excluded from the pool, and which remain unclosed by the client application.
    5. *

Having expanded the once-simple ConnectionTester interface to support both * user-specified queries and return of root cause Exceptions (via an out-param), * this interface has grown unnecessarily complex.

If you wish to implement a custom Connection tester, here is the simple * way to do it

* *
    *
  1. Extend {@link com.mchange.v2.c3p0.AbstractConnectionTester}

  2. Override only the two abstract methods

      • *
    • public int statusOnException(Connection c, Throwable t, String preferredTestQuery, Throwable[] rootCauseOutParamHolder)
      • *
    *
  3. Take care to ensure that your methods are defined to allow preferredTestQuery and * rootCauseOutParamHolder to be null.
    4. *
* *

Parameter rootCauseOutParamHolder is an optional parameter, which if supplied, will be a Throwable array whose size * it at least one. If a Connection test fails because of some Exception, the Connection tester may set this Exception as the * zero-th element of the array to provide information about why and how the test failed.

Many thanks to Carsten Heyl for running this utility and reporting the issues. -- Added lastAcquisitionFailureDefaultUser to ComboPooledDataSource's TO_STRING_IGNORE_PROPS, as some moments' Exception doesn't belong in a DataSource's toString(), and as trying to find this when stringifying close()ed DataSources provoked an infinte recursion (as an Exception was triggered trying to get the last failure info, which tries to include the stringified DataSource in its message, again provoking an Exception, ad infinitum.) Many thanks to Santiago Aguiar for finding and diagnosing this problem. -- Added better documentation of the com.mchange.v2.c3p0.cfg.xml configuration property. [Thanks to Legolas Wood for calling attention to this shortcoming.] -- Calling getHoldability() to find the default Connection holdability provokes an Error on some DB2 drivers. Added a "careful" check which catches and works around this. [Thanks to Lari Hotari for finding the problem, and providing a solution!] -- Refactored NewPooledConnection to not call event multicaster methods while holding the NewPooledConnection's lock. Holding locks while firing events is an old-fashioned way of provoking deadlocks, and it turns out c3p0 was not immune. Whoops! Another embarrassing one. Many thanks to Rhythm Tyagi and Pappu Sharadavani for finding this deadlock! c3p0-0.9.1.1 -- Marked variable "logger" in Log4jMLogger. Rare null pointer exceptions apparently result from a stale value of the previously set variable. Did the same for Log4jMLogger, although no analoguous issue has thus far been reported. [Thanks to Noa Resare and Denis on sourceforge for calling attention to this issue.] -- Hid the attribute "properties" from access via JMX, since it often contains password information. I don't think properties is particularly useful via JMX, and this seems like a better solution than returning properties with a hidden/modified password property, since users might break things unintuitively be resetting a property to a value that, according to the mbean, was the original value. [Thanks to John Sumsion for calling attention to this issue.] -- Fixed bug whereby setting any positive unreturnedConnectionTimeout forced c3p0's default effectivePropertyCycle down to 1 second. [Many thanks to Luke Dang for tracking down this bug.] -- Fixed an embarrassing bug whereby c3p0 was reflective testing for methods (setHoldability and setReadOnly) whose argument types are primitive int and boolean, by looking for Integer.class instead of int.class and Boolean.class instead of boolean.class. [Many thanks to John Kristian for tracking down this subtle, and embarrassing issue very precisely and suggesting the fix.] c3p0-0.9.1 -- Modified logging of uncleared SQLWarnings, so that warnings are emitted at INFO rather than WARNING, and via a dedicated logger [com.mchange.v2.c3p0.SQLWarnings], so that users can easily turn this behavior off. [Thanks to Oleksandr Alesinskyy for calling attention to the annoyingness of unconditionally logging all of this at WARNING.] c3p0-0.9.1-pre12a -- Fixed a NullPointerException in DoubleWeakHashMap that showed up thanks to the newly implemented canonicalization of Jdk14MLog instances. [Many thanks to Carlos Cajina for finding and reporting this bug.] c3p0-0.9.1-pre12 -- Modified Jdk14MLog to canonicalize named MLogger instances. In doing so, put the getLogger() method behind a synchronization barrier, which hopefully will resolve an odd visibility issue bug reported by a user (wherein the underlying jdk Logger appeared occasionally to be null in threads that might have initialized prior to the logger) [Thanks to Denis on Sourcefore for reporting this subtle and interesting issue.] -- Added a lastAcquisitionFailure property to PooledDataSource (and the JMX view thereof). Thanks to Troy Whittier for the suggestion, and the patch! -- SQL Warnings present at Connection acquisition, or uncleared upon Connection checkin are now logged (at WARNING level) and cleared prior to being made available as part of the pool. This is necessary to sustain the invariant that all pooled Connections are identical and interchangible; warnings are Connection state that must be managed and homogenized. [Thanks to Naxe on the hibernate forums for calling attention to this issue!] -- Resolved a rare NullPointerException which occurs when a Statement cache is closed beneath an active, checked out Connection. A client tries to prepare a Statement, but the closed Statement cache throws an NPE. Resolved this by having the closed Statement cache throw a ResourceClosedException, and having c3p0's proxy Statement recover by generating an uncached PreparedStatement. [Thanks to Sven / ford_perfect on sourceforge for finding and calling attention to this issue.] -- Added c3p0 version to C3P0RegistryManagerMBean [Thanks to Sven / ford_perfect on sourceforge for the suggestion.] c3p0-0.9.1-pre11 -- Documentation updates, and style-sheet fixes for FireFox. -- Despite the ugliness, added logic to prepend a VMID to identity tokens generated for c3p0 DataSources. See the docs (Appendix A, other configuration properties) for more information. Though there's little harm in the longer, uglier identityTokens, users who dislike them can turn them off using the property com.mchange.v2.c3p0.VMID. -- Wrote ScatteringAcquireTask, which represents a significant change to how c3p0's underlying resource pool deals with Connections acquisition failures. c3p0 is designed to retry Connection acquisition up to "c3p0.acquireRetryAttempts" times (30 by default) with a delay of "c3p0.acquireRetryDelay" milliseconds (1000 by default) between tries. Should no Connection be successfully acquired after acquireRetryAttempts, c3p0 gives up, logs an error, and frees clients waiting to check out a Connection with an Exception (declaring the pool permanently broken iff c3p0.breakOnAcquireFailure is set to true). Connection acquisition is performed asynchronously by c3p0's thread pool. Under the old implementation, when database Connections could not be acquired, a single task dispatched to the thread pool would hog a thread for the full length of the cycle -- 30 seconds by default -- spending most of that time sleeping between retries. Under the new implementation, each acquisition attempt is its own separate task, and if an acquire attempt fails, a timer is used to schedule a retry adter acquireRetryDelay without hogging any thread. I think the new implementation is unambiguously superior to the old, as it permits clients to use smaller thread pools (c3p0.numHelperThreads) and diminishes the likelihood of apparent thread pool deadlocks. However, it is too significant a change to introduce this late in the "mature" c3p0-0.9.1 series, so the old implementation is enabled by default until the c3p0-0.9.2 development cycle begins. TO USE THE NEW IMPLEMENTATION WITH c3p0-0.9.1, set... com.mchange.v2.resourcepool.experimental.useScatteredAcquireTask=true in a c3p0.properties file or as a system property. Users are strongly encouraged to set this property. You'll see better resource utilization, and I'll get to hear issue reports if I've screwed anything up in the implementation. -- Modified BasicResourcePool so that checkin (and removal) of resources is always synchronous if the pool is marked broken. [Otherwise the check-ins to a closed or broken pool may fail, as they try to use an already close()ed asynchronous task runner.] -- Modified BasicResourcePool.AcquireTask so that an interrupt always forces the whole task to end, not just a single acquisition attempt. -- Exposed numThreadsAwaitingCheckout in PooledDataSource interface and its associated MBean. [Thanks to John Sumsion for suggesting this property.] -- Prevented password from being exposed via DynamicPooledDataSourceManagerMBean. [Thanks to John Sumsion for calling attention to this oversight!] -- Fixed an error whereby DataSources.pooledDataSource( ... ) methods failed to properly set configuration properties defined on PoolBackedDataSource [e.g. numHelperThreads]. Many thanks to John Sumsion for noticing the problem and sending the fix! -- Fixed AbstractConnectionCustomizer to implement (with no-op) methods the current definition of the ConnectionCustomizer interface. (Failed to update after modifying an early version of this interface.) -- Modified NewPooledConnection to only collect stack trace information on close() when we are debugging at FINEST or DEBUG (log4j) level. Previously, stack trace information was collected anytime a c3p0 PooledConnection was close()ed. This was unnecessary, although the performance cost was probably small to negligible, since PooledConnections are typically reused many times before they are close()ed. Stack trace information is still captured when PooledConnections are destroyed due to an error, rather than an ordinary call to close(). -- Hid the getLastXXXFailure(user, password) from the operations list of DynamicPooledDataSourceManagerMBean. The stack traces of failures are visible via the sampleLastXXXFailureStackTrace(); there's no need to expose the Throwbales as well via JMX. -- Added convenience methods getNumPooledDataSources() and getNumPoolsAllDataSources() to C3P0Registry and the related MBean. [Thanks to lukeda on hibernate forums for calling attention to the need for a pool count, since DataSources can wrap multiple pools associated with different authentications.] -- Eliminated the "trial Connection acquisition" added to c3p0-0.9.1-pre10 when PooledDataSources construct the pool with their default authentification information. Effectively we trust that the default auntentification is good, while we distrust client-specified (or JMX-queried) username/password combinations, and perform the extra check. This is a compromise, as users who frequently create and destroy DataSources don't like the extra overhead of the trial Connection acquisition, but we really want to avoid the initialization of bad pools when users misspecify authentification information. We've also prevented mere queries of pool status from triggering the initialization of a non-default-authentification pool. Only calls to getConnection(user, password) will provoke the initialization of a non-default-auth pool. Querying a non-default pool -- e.g. getNumBusyConnections( "steve", "test" ) -- will throw an Exception if no Conections have ever been requested for ("steve", "test") rather than initializing a new pool. [Thanks to Jiji Sasidharan for calling attention to this issue.] -- Finally rationalized C3P0Registry's Object retention policy. C3P0Registry retains references to all C3P0 DataSources, to provide a central point of client access for users, and to ensure that multiple JNDI lookups within a single VM result in the same DataSource instance. This is both intuitive, and avoids multiplying Threads and pools. In previous versions of c3p0, hard references were retained indefinitely. Closed DataSources hold no non-memory resources, and are small Objects, but in unusual scenarios wherein very many c3p0 DataSources are created and destroyed within the lifetime of a single VM, this amounts to a memory leak. C3P0Registry now retains hard references to DataSources so long as they have not been close()ed (or DataSources.destroy()ed). When they have been close()ed, only weak references to c3p0 DataSources persist, and they are eligible for garbage collection. [Thanks to Jeremy Grodberg for calling attention to this as a real-world issue.] -- Removed some of the new pool stat params which distractingly appear in ComboPooledDataSource's toString() method (and c3p0 pools' config dump). c3p0-0.9.1-pre10 -- Exposed statement pool stats via PooledDataSource interface and MBean. Added accessors to the statement cache, pool, pool manager, and AbstractPoolBackedDataSource. -- Fixed a bug whereby multiple near-simultaneous Connection requests failed to provoke sufficient pool growth/Connection acquisition. This is a bug reintroduced in c3p0-0.9.1-pre4, and is a duplicate of an early issue, resolved under the old pool size management scheme. c3p0 must (and does) keep track not only of its current size and pending growth, but also the number of potentially unserved recent Connection requests. c3p0-0.9.1-pre4 thru c3p0-0.9.1-pre9 failed to make use of the incoming request count when deciding whether and how much to grow the pool. Many thanks to John Kristian for calling attention to this subtle issue. -- Exposed information about Connection test failures (failure count of each type of test, stack trace of last failure and last failure of each type) via the PooledDataSource interface and its assiciated MBean. -- Fixed a rare situation where a Connection test on check-out could be performed by a Thread holding the pool's lock, if an initial attempt to checkout a Connection failed and a second checkout attempt is initiated internally. The recursive checkout is now performed without the pool's lock. -- Established a consisent policy re logging of Connection test failures. They are now logged at FINE level (DEBUG under log4j). Previously tests on checkin and checkout were logged at FINE, but idle tests were logged at INFO. Is it worth letting this be configurable, as some users may prefer to see test failures under normal operation? -- Modified C3P0PooledConnectionPoolManager to perform a trial Connection acquisition before trying to establish a pool, as pools established on bad database or authentification information churn indefinitely trying to acquire minPoolSize Connections, clogging up the thread pool and sometimes leading to "APPARENT DEADLOCKS" if users touch a pool with bad authentification information. -- Defined UnifiedConnectionTester (and AbstractConnectionTester) so that ConnectionTesters can provide any Exception associated with a failure, which will show up as the "root cause" of the Exception eventually thrown to signal the failure. -- Added logging at WARNING level when a Connection tester reports the database is invalid, triggering a reset of the Connection pool. c3p0-0.9.1-pre9 -- Updated the documentation. It is now fully current. -- Changed the name of the jboss configuration mbean from com.mchange.v2.c3p0.mbean.C3P0PooledDataSource to com.mchange.v2.c3p0.jboss.C3P0PooledDataSource, in order to distinguish the jboss configuration stuff from the normal management beans, which really are quite different. The old com.mchange.v2.c3p0.mbean.C3P0PooledDataSource still exists, so that existing users don't see anything break, but only the new version will be updated to support new parameters. -- Added a means by which users can suppress JMX MBean registration if they wish. Setting the property com.mchange.v2.c3p0.management.ManagementCoordinator to com.mchange.v2.c3p0.management.NullManagementCoordinator will prevent mbean registration. (Advanced users can also use this to install their own implementations of the ManagementCoordinator interface, though I doubt many people will find this useful.) -- Fixed infinitely loop in ComboPooledDataSource.setFactoryClassLocation( ... ) [introduced with the reorganization of ComboPooledDataSource to inherit from AbstractPoolBackedDataSource (?)] -- Added some code to warn on common spelling errors of c3p0.properties and c3p0-config.xml (Users have frequently mistaken the digit 0 for the letter O in c3p0.) -- Wrote a DynamicMBean for PooledDataSources. It seems to work, covers both ComboPooledDataSource and "wrapping" PoolBackedDataSources, and should cover new config parameters and accessors automatically. -- More refinements to connection test logic. We test proxy Connections when there's a statement cache and a test query (to save time, since the test query is likely cached), we test physical connections if we'll need to do the slow, default test (statement caching doesn't help), or if there is no statement cache. -- Removed the stub servlet I'd previously added. Although it jdk1.5+, the JMX approach is a better one for monitoring and modifying c3p0 pools at runtime, and I'm going to focus on that for now. (If there's a lot of clamor for it, I'll add back and flesh out the servlet. It just doesn't seem like a great use of my time for now.) -- Modified build to create a separate jdk1.3 compatable jar by stripping source of lines beginning with "assert". I want to start using assertions, but will keep them to recognizable, strippable one-liners. -- Modified DriverManagerDataSource to handle its driverClass parameter in a less fragile way. Rather than attempting to load the driverClass on property set, DriverManagerDataSource now lazily tries to load the class upon its first call to getConnection() after the property is initialized or updated. c3p0-0.9.1-pre8 -- Fixed bug whereby jdbcUrl and driverClass were not initialized properly if set in config files rather than in code. [Thanks to Felipe Dominguez for calling attention to this problem!] -- Changed AbstractPoolBackedDataSource from a non-public class in com.mchange.v2.c3p0 to a public class in com.mchange.v2.c3p0.impl to workaround fragilities associated with sun bug id #6342411, wherein reflective invocation of public methods on a non-public class fail, even when involed via a public base-class. -- Fixed NullPointerException (introduced on -pre7) on initializing with a named config. -- Continuing along the same lines, modified C3P0Registry and C3P0ManagementCoordinator to unregister (both from C3P0Registry and associated MBeans on DataSource close. When all PooledDataSources are unregistered, the C3P0RegistryManager MBean unregisters as well. -- Modified ActiveManagementCoordinator to check for, and unregister, the C3P0Registry mbean prior to registration, to prevent conflicts on undeploy/redepoloy cycle. [Thanks to Ben Groeneveld for calling attention to this problem, and suggesting the fix.] -- Modified C3P0PooledConnectionPool to perform Connection tests on the raw physical Connection rather than the proxy Connection, when possible (i.e. when we're using a C3P0 PooledConnection implementation that we know how to get underneath of). This is better because 1) it's slightly faster; 2) it's significantly faster on failure, as C3P0 PooledConnections test Connections after a failure with statusOnException(), leading to an unnecessary double-check; and 3) authors of custom ConnectionTesters can use vendor-specific API to test Connections if they wish. c3p0-0.9.1-pre7 -- Defined the ConnectionCustomizer interface as a hook through which clients can "set up" newly acquired or checked out connections (and clean up prior to check-in or destruction). Added config param connectionCustomizerClassName. -- Formerly unused config parameter propertyCycle now controls how frequently c3p0 checks timestamps against expiration parameters (maxIdleTime, maxIdleTimeExcessConnections, maxConnectionAge, unreturnedConnectionTimeout) -- Added config parameters unreturnedConnectionTimeout and debugUnreturnedConnectionStackTraces, reluctantly but by popular demand. If unreturnedConnectionTimeout is set, Connections will be automatically destroyed and removed from the pool if not returned in the given number of seconds. If debugUnreturnedConnectionStackTraces is also set, stack traces will be captured on check-out of any Connection, and the stack traces that were unreturned and cleaned up by the pool will be logged. Any clean-up of an unreturned Connection is logged at INFO level, in hopes of annoying people into cleaning up their code and close()-ing their Connections reliably. -- Added config parameter maxIdleTimeExcessConnections. Connections in excess of the pool's minimum size will be expired out if they remain idle for longer than maxIdleTimeExcessConnections. [Thanks to Navin M. and Ben Groeneveld for the suggestion.] -- Added configuration parameter maxConnectionAge to limit the absolute age of Connections (age in seconds from acquisition, rather than in seconds form last check-in). -- Put more status accessors in ThreadPoolAsynchronousRunner and exposed thread pool state via JMX (PooledDataSourceManagerMBean). -- Preliminary support for management via mbeans/jmx under jdk1.5+ is implemented. (These mbeans are distinct from the mbean designed for configuring c3p0 under jboss, and are in the package com.mchange.c3p0.management.) Currently, pool statistics are instrumented, as well as pool reset operations, but viewing and modifying the pool configuration parameters is not supported. (I'll write a dynamic mbean to capture this stuff; there are too many config properties I'm already updating by hand in too many places. Later.) [Thanks to Ben Groeneveld for the suggestion, including some nice sample code!] -- Added configuration parameter maxAdministrativeTaskTime, which forces interrupt() to be called on pool administrative tasks (Connection acquisition, destruction and testing; prepared statement destruction) if these tasks seem to hang. This is one strategy for dealing with database that hang and lead to deadlock messages and eventually large memory footprints. It's useful only if the hanging operations respond to interrupt()s, not thread-monitor related deadlocks (which hopefully don't ever happen). c3p0 should recover from any Exceptions provoked by the interrupt() calls. (Hopefully improvements to GooGooStatementCache have rendered this parameter largely unnecessary by resolving the most common source of deadlocks.) -- Major revision to GooGooStatementCache that may eliminate most APPARENT DEADLOCK messages. c3p0-0.9.0 introduced a complicated implementation of closeAll(), in order to ensure that Statement and Connection close did not happen simultaneously. Upon review, there was a significant bug in the implementation, and even when corrected, the strategy is itself prone to deadlocks should the ThreadPool become saturated with destroy tasks, which block awaiting statement remove tasks. Rewrote closeAll() as a simple synchronous method, rather than simulating synchrony with wait()/notifyAll(), but with care not to hold the StatementCache's lock during Statement.close() calls. There is a slight loss of asynchrony, as Statement.close() methods are executed sequentially rather than simultaneously, but as a practical matter, since the sequential destruction occurs asynchronously in the thread pool and is invisible to clients, both client-observed and over-all performance should not suffer. (It may even be improved, as the 0.9.0.x strategy was complicated and had some overhead.) Note: This revision should also eliminate occasional ConcurrentModificationExceptions associated with the Statement cache. -- Changed asynchronous tasks implemented as anonymous inner classes to named inner classes, so that users reviewing active and pending tasks (usually in trying to make sense of an APPARENT DEADLOCK) have a better idea of what's going on. -- Major revision to GooGooStatementCache that may eliminate most APPARENT DEADLOCK messages. c3p0-0.9.0 introduced a complicated implementation of closeAll(), in order to ensure that Statement and Connection close did not happen simultaneously. Upon review, there was a significant bug in the implementation, and even when corrected, the strategy is itself prone to deadlocks should the ThreadPool become saturated with destroy tasks, which block awaiting statement remove tasks. Rewrote closeAll() as a simple synchronous method, rather than simulating synchrony with wait()/notifyAll(), but with care not to hold the StatementCache's lock during Statement.close() calls. There is a slight loss of asynchrony, as Statement.close() methods are executed sequentially rather than simultaneously, but as a practical matter, since the sequential destruction occurs asynchronously in the thread pool and is invisible to clients, both client-observed and over-all performance should not suffer. (It may even be improved, as the 0.9.0.x strategy was complicated and had some overhead.) -- Users still occasionally report seeing "APPARENT DEADLOCK" messages from ThreadPoolAsynchronousRunner. Previously, most reports had to do with cached PreparedStatements that hang when closed. Previous fixes (in 0.9.0) seemed to resolve these problems. Most new reports have to do with Connection acquisition or Connection close() tasks hanging indefinitely, with statement cacheing not necessarily involved. It's unclear whether these reports stem from a c3p0 bug, or rare situations in which various JDBC driver hangs hang c3p0. (If the condition is temporary, c3p0 recovers after the "APPARENT DEADLOCK" warning. In any case, ThreadPoolAsynchronousRunner has been modified to provide much better debug information, particularly in jdk1.5 environments, where hung Thread stack traces are dumped. -- Modified the build file and refactored C3P0Config / C3P0ConfigUtils / C3P0ConfigXmlUtils to make sure that c3p0 still runs under jdk1.3, even though it only builds under jdk 1.5. JMX support is 1.5 only, and XML config depends on the availability of standard XML extensions under jdk 1.3. (This is going to get harder, as I hope to start using assertions. For the moment, assertions are commented out. I think I'll have ant filter away the assertions for 1.3 builds and leave them in otherwise, based on a build property. -- Significantly reorganized (hopefully simplified) of C3P0Registry and ComboPooledDataSource. Much of the complication of all this is supporting the most annoying, least used, but nevertheless very important feature of supporting JNDI lookups across JVM boundaries via Serialization or JNDI References. -- Reorganized ComboPooledDataSource to inherit from PoolBackedDataSource. In doing so, changed setConnectionPoolDataSource() of PoolBackedDataSource to throw a PropertyVetoException. (It is a "constrained property" now.) The very, very few users who call this method directly may have to update their code to handle the potential Exception. This change does not affect compatability for clients that use ComboPooledDataSource or who create PoolBackedDataSources via the c3p0's factories (e.g. DataSources). -- Fixed bug whereby config parameter breakAfterAcquireFailure did not take effect at the ResourcePool level. -- Fixed bug whereby initialPoolSize parameter failed to take effect at the ResourcePool level. -- Fixed a bug whereby Connection tests on checkout held the pool's lock, preventing other activity during the Connection test. [Thanks to John Sumsion for calling attention to this subtle problem.] -- ThreadPoolAsynchronousRunner has seen some minor efficiency improvements (a task that calls interrupt() long-running tasks on post-deadlock blocked, replaced threads no longer runs when there are no post deadlock blocked, replaced threads). -- Previous versions used a Stringified identityHashCode() as a unique ID for various C3P0 objects. This was not correct (and bit at least one user in practice), as identityHashCode()s are not guaranteed unique, and in practice are not on 64-bit VMs. c3p0 now checks identityHashCodes to make sure they are not reused, and if seen before appends a count to keep unique IDs unique. [Many thanks to Prishan Makandurage for calling attention to this issue.] -- Fixed fact that statusOnException() in NewPooledConnection() ignored preferredTestQuery parameter, always using the very slow default connection test rather than the user-defined test. [Thanks to Andrea Luciano for calling attention to this issue.] -- C3P0PooledConnection (part of the "traditionalReflectiveProxies" codebase that's largely been superceded, but that is still nominally supported) held a static reference to a ClassLoader, in some cases preventing the ClassLoader from being garbage collected (for example when webapp contexts, with context specific Classloaders are undeployed by some app servers). This was entirely unnecessary, as the cached reference was used exactly once in the lifecycle of the class. The reference to the ClassLoader is no longer stored. [Many thanks to Michael Fortin for very specifically tracking down this subtle problem!] -- Added logic to log individual acquisition failures at INFO level if acquireRetryAttempts <= 0. if num_acq_attempts <= 0, we try to acquire forever, so the end-of-batch log message below will never be triggered if there is a persistent problem so in this case, it's better flag a higher-than-debug-level message for each failed attempt. [Thanks to Eric Crahen for calling attention to this issue.] c3p0-0.9.1-pre6 -- Wrote a stub of a status-monitoring servlet. Not yet documented, or even usefully functional, but hopefully will be soon. -- Updated documentation to include new config file format, including named and per-user config. Docs could still use some work, but the functionality is now described. -- For consistency, the parameters user and password are now configurable via config files and System properties. -- Modified DefaultC3P0ConfigFinder to properly give greater precedence to System properties than to XML-defined unspecified user, default config values. -- Added WARNING logging of create SQL and original database Exception when creation of an automaticTestTable fails. [Thanks to Alexander Grivnin.] -- Added logic so that the Exception assoicated with the last failed acquisition attempt in a round of attempts is logged along with the failure if the acquisition attempts. [Thanks to Barthel Steckemetz and Patrick Eger for calling attention to this issue.] -- Fixed a problem whereby modifying the config of a ComboPooledDataSource programmatically, while in use, causes previously checked-out Connections to be close()ed underneath the user. Changing configs midstream still causes a complete resetting of the pool (because the pool holds most config params as immutable to avoid having to synchronized for every config param read), but old Connections from superceded pools will remain valid until they are rechecked into the pool. [Thanks to hhu for noticing this problem!] -- Fixed a resource leak whereby Connections which could not be reset after client-initiated close() were properly "excluded" from future inclusion in the pool, but never checked back into the pool to be destroyed. (Excluded resources are simply marked for destruction rather than reassimilation on checkin.) [Many thanks to Levi Purvis for tracking this down!] c3p0-0.9.1-pre5a -- "test-classpath" was erroneously specified in build.xml to include some extra jar files, which rendered undetectable (to my tests) the fact that com.mchange.v1.lang.BooleanUtils was not jarred up into c3p0-0.9.1-pre5.jar as it needed to be. Very, very embarrrassing. [Thanks to Goksel Uyulmaz for calling attention to this gaffe.] c3p0-0.9.1-pre5 -- reorganized synchronization of getConnection() in DriverManagerDataSource, so that a lock-up in one Connection acquisition attempt does not prevent other threads from accessing the DataSource. [Thanks to Fabian Gonzalez for calling attention to this occasional deadlock.] c3p0-0.9.1-pre4 -- added overrideDefaultUser and overrideDefaultPassword parameters, and a pooledDataSource( ) factory method which specifies override authentification info, regardless of the user and password properties set on the DataSource. -- Reimplemented resource acquisition in BasicResourcePool so that each Connection acquisition is a separate asynchronous task, to avoid tying up the pool with very long, multiple acquisition tasks. Ended up being a total rewrite of pool size management. Pools should be much more conservative in acquiring new Connections. They won't grow to maxPoolSize as easily as before. This is a big change. We'll see how it holds up as people beat the crap out of it. c3p0-0.9.1-pre3 -- Added some extra logging of resource destruction, to help debug cases where the resources are removed from the pool, but appear not to have been properly cleaned up. -- Finished implementation of new C3P0Config, added constructor methods to various DataSource implementations that accept a configName parameter for named configurations, and modified the DataSources class to use the new configuration approach instead of PoolConfig wherever possible. c3p0-0.9.1-pre2 -- Continued implementation of new C3P0Config, including XML parsing and setting of default values. Still have to test XML config, and implement named and per-user configs. -- Changed policy of BasicResourcePool to keep accidentally overacquired resources so long as the pool is kept below maxPoolSize, rather than immediately discarding Connections beyond the number we intended to acquire. -- Fixed two issues whereby checking in resources to closed pools (both Connection and Statement pools) provoked Exceptions. Check-ins should succeed, even to close()ed pools, with resources silently destroyed if the pools ae closed. [Thanks to Chris Kessel for finding both of these issues.] -- Modified to a one-statement-cache-per-pool model, rather than a global-statement-cache-for-all-pools, consistent with the general philosophy that config parameters are on a per-auth-pool basis. -- Fixed a deadlock which could occur if a pool is closed at the same time as one of its Connections is closed. One thread gets the pool's lock, then tries to get a PooledConnections lock to close it. An ordinary client closes a Connection, which acquires the PooledConnection's lock, and then tries to check back in to the pool, requiring the pool's lock. Broke the deadlock by making the destruction of resources on pool close asynchronous, by a Thread without the resource pool's lock.. [Many thanks to Roger Westerlund for sending a full thread-stack dump capturing this deadlock!] -- Completed transformation to one C3P0PooledConnectionPoolManager per PoolBackedDataSource model. c3p0-0.9.1-pre1 [This is a half-assed internal release... it compiles and works, but mostly it's just a checkpoint as c3p0 undergoes significant transformations.] -- Deprecated PoolConfig, and began implementation of new C3P0Config approach to configuration. -- Partial transformation of C3P0PooledConnectionPoolManager from shared-manager for several DataSources model to simple one-pool-per-DataSource model enabled by canonicalization of DataSources. c3p0-0.9.0.4 -- In a subtle but major modification of BasicResourcePool, changed checkin/checkout behavior from FIFO to LIFO to increase the likelihood that unnecessary Connections pooled at peak times idle long enough to expire. [Many thanks to Vlad Ilyushchenko and hontvari on sourceforge for noticing this important issue and suggesting the fix.] c3p0-0.9.0.3 -- Added code to mbean C3P0PooledDataSource to automatically create JNDI subcontexts if a JNDI name is specified for which the full path has not been created (analogous to mkdir -p in UNIX). [Thanks to David D. Kilzer for noticing the issue, and for submitting the fix!] -- Added logic to GooGooStatementCache to ensure that multiple threads do not try to close the same PreparedStatement, in order to try to resolve longstanding PreparedStatement.close() freeze issues. [Thanks to cardgames on sourceforge for noticing that the freezes seem to occur when several threads are trying to close() just one statement!] -- Added some checks in DriverManagerDataSource (as well as WrapperConnectionPoolDataSource) so that a mismatch between JDBC URL and driver does not lead to null Connection references and downstrem NullPointerExceptions. [Thanks to Richard Maher for calling attention to this issue.] -- Undid some unnecessary synchronization in WrapperConnectionPoolDataSource, which would cause deadlocks when the acquisition of a Connection from the underlying driver froze for some Thread. (Other threads would then block trying to access the WrapperConnectionPoolDataSource.) [Thanks to Fabian Gonzales for calling attention to this issue, and for providing a VM thread stack dump to help chase it down!] -- modified BasicMultiPropertiesConfig to never attempt to read the resource "/", representing (in this case) System properties, as a stream, which under some classloaders caused ClassCastExceptions. [Thanks to Joost Schouten for calling attention to this issue.] -- fixed initial check of the readOnly and typeMap properties of Connections, so that users don't see disconcerting Exceptions at debug log levels if their drivers don't support these parameters. -- Added jar attributes Extension-Name, Specification-Vendor, Specification-Version, Implementation-Vendor-Id, Implementation-Vendor, and Implementation-Version [per request of Pascal Grange]. -- Added some extra debugging information for peculiar situation where an IdentityTokenized is constructed and registered with C3P0Registry, but coalesces to a different Object. This should never happen, as freshly constructed IdentityTokenizeds should have String versions of their identity hashcodes as tokens, and upon their registration, no copies should yet have been created and registered. [Thanks to Jose Rodriguez for noting this issue.] c3p0-0.9.0.2 -- added debug-level logging of connection tests and results -- tightened up means by which the readOnly and typeMap properties of Connections are reset, so that users don't see disconcerting Exceptions at debug log levels if their drivers don't support these parameters. -- fixed problem in BasicResourcePool that left the immediately-close-checked-out-connections option in the close() method ineffective, meaning Connections checked-out from a pool would leak unless clients remembered to check them into pool for destruction. -- fixed bug wherein connection-testing on checking occured in a thread holding the pool's lock, leading to pool hangs or deadlocks if a connection hangs. [Thanks to Tobias Jenkner for calling attention to this problem!] c3p0-0.9.0.1 -- modify BasicPropertiesConfig to not throw class cast Exceptions in the rare case that a Properties object (presumably System properties rather than a file derived props Object) contains (via the Map/Hastable API) non-String keys or values. [Thanks to Prima Upot for calling attention to this issue.] -- fixed a build issue where some classes required for code generation were not necessarily compiled prior to the code generation step, causing builds to fail. [Thanks to James Neville for calling attention to this issue.] c3p0-0.9.0 -- under some circumstances, the current list of ThreadPoolAsynchronousRunner's deadlock detector seems to hold onto a lot of memory... presumably this is when long pending task lists build up for some reason... nevertheless, we now dereference the "current" list in between deadlocker detector invocations. The "last" list has to be retained between invocations, but the "current" list need not be. [Thanks to Venkatesh Seetharamaiah for calling attention to this issue, and for documenting the apparent source of object retention.] -- modified log4j and jdk14logging MLog implementations to test for library classes upon classload (MLog class only tests for the presence of the mlog implementations, which doesn't notice if their dependant classes aren't there -- dependent classes must test for the presence of the libraries.) -- Modified GooGooStatementCache to warn as INFO (and with a descriptive message in debug) of multple PreparedStatement preparation. [Thanks to mxnmatch on hibernate's forum for calling attention to this issue.] -- Modified BasicResourcePool to not warn on expected InterruptExceptions that occur if clients are waiting for a Connection when the pool is closed. [Thanks to Blunted on hibernate's forum for calling attention to this issue.] c3p0-0.9.0-pre6 -- Modified thread pool's strategy for dealing with deadlocks to prevent OutOfMemoryErrors from sudden spawning of multiple threads to clear backlogged tasks. [Thanks to Greg Whalin for calling attention to this problem.] -- Fixed bugs in debug reporting of nested Exceptions/Warnings when converting or rethrowing SQLExceptions [thanks to an anonymous sourceforge poster for finding this] -- modified BasicResourcePool to shorten the period during which the pool's lock is held during resource acquisition -- maxIdleTime is generally enforced every (maxIdleTime / 8) seconds. Added logic to ensure that even for very long maxIdleTimes, the longest maxIdleTime will ever go unenforced is 15 minutes. -- Very tentative initial support in build for JUnit tests -- Fixed documentation typos and added sample config for Tomcat 5.5. [Thanks to David Newcomb for finding the typos and to Carl F. Hall for the sample config!] -- ProxyConnections were not properly resetting readOnly, holdability, catalog, and typeMap properties on Connection close. Fixed. [Thanks to Andy (bjorkmann?) for calling attention to this bug.] -- Added a complicated workaround to issues that may occur when a Connection and its child statements simultaneously try to close. GooGooStatementCache's closeAll(Connection c) method now wait()s for all Statements to close prior to returning, avoiding such issues (Oracle deadlock, mysql NullPointerException), though dramatically complicating the code. Grrr. Theoretically, drivers should be robust to the simultaneous closing of Statements and Connections, but they're not, so my code gets to be more complicated. [Thanks to Juan Perez, Daniel Edberg, and Damien Evans for calling attention to this issue.] c3p0-0.9.0-pre5 -- Proxy classes were overaggressively invalidating themselves in response to a signalled Connection error. This problem was very similar to the problem fixed in 0.8.5-pre9, except for rather than the PooledConnection too quickly closing its inner Connection, the proxies too quickly detached themselves from the pooled Connection, considering themselves broken, after a Connection error event. Users expect to be able to work with their Connections even after c3p0 has in its conservatism decided they no are no longer worthy of a place in the pool. [Thanks to "Geoff Fortytwo" for finding and helping to track down this issue.] -- Fixed issue that prevented user-defined ConnectionTesters from being used. c3p0-0.9.0-pre4 -- Fixed NullPointerException on double-close of proxy Statements. [Thanks to Stephen Waud for finding this bug and tracking it down.] -- Modified C3P0PooledConnectionPool to generate a more informative Exception (one that includes the stack trace of the initial problem) when a Connection test fails. [Thanks to novotny from the hibernate forums for calling attention to this issue.] ` -- PooledDataSources now set SQLState 08001 on SQLExceptions resulting from a determination by the pool that the database is down or unavailable. [Thanks to ml2709 on the hibernate forums for calling attention to this issue.] -- Modified ThreadPoolAsynchronousRunner to enforce its max task time even on one-off "emergency threads" used to flush the pool of tasks after an apparent deadlock. Hopefully this will help to eliminate the OutOfMemoryErrors that users occasionally see if some Database operation starts to fail by blocking indefinitely, and is attempted many many times. As long as these operations are susceptable to interrupt(), this should resolve the problem. (If tasks block in a way that is immune to interrupt(), there is little c3p0 can do to recover the Threads and prevent the number of blocked Threads from growing until memory runs out.) [Thanks to Jean-Christophe Rousseau and Arup Vidyerthy for calling attention to this issue.] -- Wrapped System.getProperties() calls in try / catch blocks that catch and log the SecurityExceptions, and ignore System properties if access to them is forbidden. c3p0.properties configuration should work fine in security-controlled apps, but you won't be able to configure c3p0 using "java -Dc3p0.xxxx=yyy ..." Since most users use c3p0.properties for configuration, I don't think this will be a major problem. In the future, I may be able to work around the restriction by having ask only for c3p0-specific System properties, rather than calling the unrestricted System.getProperties() method. [Thanks to zambak on SourceForge for calling attention to this issue.] c3p0-0.9.0-pre3 -- Modified generated proxy classes to properly report the type of the closed Object if used after call to close(). -- Fixed a really embarrassing oversight, wherein cached PreparedStatements were being physically close()ed prior to their return to the cache! Tests on psql failed to reveal this, because psql-7.4 Statement.close() does nothing to invalidate the Statement! [Many thanks to tbayboy on hibernate's forum for discovering this issue, and to fassev, also on hibernate's forum, for correctly deducing the cause!] -- Fixed an embarrassing oversight where operations of proxy Statements and ResultSets failed to mark transactions as potentially dirty, leading to the possibility that Connections with unresolved transactional work could be checked into the pool. -- Modified c3p0 Statements to no longer permit calls to getConnection() after Statement close, and to null out the backreference to the parent Connection. [Thanks to Edward Bridges for pointing out the issue.] -- NewPooledConnection threw a NullPointerException on close() of a ResultSet whose creating Statement had already been closed. Fixed. [Thanks to Edward Bridges for pointing out the problem.] -- Modified PoolConfig to trim() read-in c3p0.properties to avoid NumberFormatExceptions if there is extra spacing in the file. [Thanks to johnchan for calling attention to this issue.] c3p0-0.9.0-pre2 -- Documentation updates and improvements -- Integrated configurable wrapper logging library, so that c3p0 can log to log4j or jdk14logging. c3p0-0.9.0-pre1 -- First pass at documentation of JBoss integration. -- Better one-per-JVM canonicalization (IdentityTokenized, IdentityTokenResolvable, C3P0Registry) -- First implementation of MBean for JBoss compatability -- Fixed JNDI ref-based DataSources c3p0-0.8.5.1 -- Fixed a really embarrassing bug that made Statement pooling worse than useless where users have set maxStatements but not maxStatementsPerConnection. maxStatementsPerConnection -- that is, 0 -- was being used in place of maxStatements on Statement cache initialization. [Thanks to Gwendal Tanguy for not only, calling attention to this issue, but tracking down the precise location of the bug!] c3p0-0.8.5 -- Documentation updates and improvements -- Fixed an issue where failures on reset() of a pooled Connection caused a Connection error to be signalled, without updating the status of the PooledConnection to indicate that it is broken. Thanks to Henry Le for calling attention to this issue. c3p0-0.8.5-pre9 -- Modified c3p0's behavior on detecting an apparently broken Connection. Previously c3p0 would very aggressively close any Connections that, after an Exception, failed to pass a Connection test. This sometimes surprised and confused users, when Conections they expected to remain open were closed from underneath them. Under normal circumstances, a Connection which has failed its Connection test is broken anyway, so closing it does no harm. But under some circumstances, a Connection may fail its Connection test, but still be partly functional from the application's point of view. So, now c3p0 simply marks Connections that fail their Connection test following an Exception as broken, and excludes them from future re-entry into the pool, but leaves those Connections open for users to continue working with them prior to their explicit close() of the Connection. [Thanks to Julian Legeny for calling attention to this issue.] -- Modified c3p0's logging behavior to be a little bit less annoying. Rather than frequently printing duplicate stack traces to be sure root cause Exceptions are logged as well as converted, rethrown Exceptions, c3p0 now checks the Java version, and uses the initCause() method to log the root cause in versions 1.4 and above. Also, some Exceptions that were expected and thrown without information as to the cause now use the initCause() method to provide this in JDK 1.4 and above. [Thanks to Ruslan Gainutdinov, Anthiny Pereira, Carsten ????, and Eric Hsieh for calling attention to these issues.] -- Fixed bug whereby proxy wrappers were sometimes placed around null return values from native Objects, particularly Statement's getResultSets() method. [Thanks to Ruslan Gainutdinov for calling attention to this issue.] -- Fixed bug in NewProxyConnection whereby setTransactionIsolation was called even if the Connections' isolation level had not been changed from its default. [Thanks to Levent Aksu for reporting this bug.] c3p0-0.8.5-pre8 -- Added C3P0ProxyStatement and rawStatementOperations for accessing vendor-specific Statement API. -- Fixed bug whereby recently added properties could not be configured properly via a PoolConfig Object passed to the DataSources factory method. [Thanks to Julian Legeny for finding this bug.] -- Undid new behavior whereby c3p0 warns when it detects that a transaction has not been comitted or rolled-back prior to close and must be automatically rolled-back. Because c3p0 autorollsback conservatively, whenever it is possible that there may be any transactional resources held by the Connection being checked in, users who make read-only queries, then close without commit or rollback, saw the warning, and became annoyed. Warning when it's "right" is hard, and would involve paying attention to the substance of user-queries, as well as the transaction's isolation level. In the future, when c3p0 offers better control over logging, we'll make the warning optional. Note that this release only undoes the warning -- the new logic that detects potential transactional work and only rollsback when there has been some remains. [Thanks to David Graham for calling attention to this issue.] -- Synchronized StatementCacheKey.find( ... ) method. Subclasses of StatementCacheKey have always explicitly relied upon this method being synchronized in the parent class, but somehow it was not... [Thanks to Manfred Hutt for reporting this bug.] -- Modified both PooledConnection implementations to reset the transaction isolation level on PooledConnection.reset() -- Finalized PooledDataSource api for pool stats and resets. c3p0-0.8.5-pre7a -- Fixed some bugs in new Proxy classes relating to close(), methods, especially NullPointerExceptions on duplicate close() operations. -- Fixed some misleading documentation re: testConnectionOnCheckin and automaticTestTable vs. preferredTestQuery -- Changed wording of warning message on purge of idle-test-failing resource to no longer suggest that some user action is required. [Thanks to Krishna Kuchibhotla for calling attention to this issue.] -- Modified GooGooStatementCache so that its close() is synchronous, since when the Statement cache is closed, it's asynchronous runner has often been closed already underneath it. (Actually changed as of c3p0-0.8.5-pre7, but forgot to log it.) c3p0-0.8.5-pre7 -- Added flag (in both new and tradional reflective proxies) to prevent automatic rollbacks on Connection close()es immediately post- commit(), rollback(), or setAutoCommit(). -- DatabaseMetaData now properly returns proxy rather than naked raw Connection. [Thanks to jhoeller on the hibernate forums] -- In response to an apparent BEA WebLogic specific problem with DriverManager.getConnection( ... ), DriverManagerDataSource now caches its driver and uses Driver.connect( ... ) rather than DriverManager.getConnection() when acquiring Connections. Thanks to Lars Torunski for calling attention to this issue. -- Fixed some missing synchroniztion that really should be provided for accessors and mutators of DataSource bean properties. -- Added config parameter automaticTestTable, which takes the name of a table that c3p0 will create and use as the basis for Connection tests. It's easier to use than preferred test query, because you don't have to ensure the existance of any tables in the schema prior to using a Pooled data source. -- Fixed idiotic oversight whereby Connections didn't get their transaction status resolved and reset on check-in... c3p0-0.8.5-pre6 -- Modified resource pools to only conditionally support async ResourcePoolEvent generation. Since c3p0 doesn't use ResourcePoolEvents, we can do without the superfluous CarefulRunnableQueue, and its associated Thread, which was serving as an event queue. -- Fixed bug where asynchronous refurbishment (testing) of resources would be attempted even on check-in to a closed pool, whose async threads had terminated. -- c3p0 now supports the following new configuraion parameters: preferredTestQuery, testConnectionOnCheckin, checkoutTimeout, and maxStatementsPerConnection. preferredTestQuery should allow c3p0 to test Connections (whether on checkout, checkin, or after a specified idle time) much more efficiently than with it's default test [a call to getTables(...) on the Connection's DatabaseMetaData.]. checkoutTimeout allows clients to break out of a getConnection() call after a a specified time period, rather than waiting (potentially indefinitely) for a new Connection to be acquired from the database, or a checked-out Connection to be rechecked in. testConnectionOnCheckin should be self-explanatory. maxStatementsPerConnections allows users to specify how many statements to cache on a per-connection base instead of, or in addition to, the global limit maxStatements. -- Fixed various bugs relating to the referenceMaker and getReference() method of ComboPooledDataSource. -- Added TestUtils class to util package (modified from an old C3P0TestUtils class now removed from the test directory), which now contains facilities for establishing the identity of the physical Connection beneath a proxy, so that tests can check to see when they are seeing the same physical Connections recycled. [Thanks to Julian Legeny for calling attention to this issue.] -- Modified code generators so that inner objects of all NewProxy classes go to null on object close(). Closed proxies should be hopelessly broken. -- Added missing parameter "usesTraditionalReflectiveProxies" to ComboPooledDataSource -- Fixed bug whereby CarefulRunnableQueue threads linger indefinitely, even though their close() method has been called. [Thanks to muirwa on the hibernate forums for calling attention to this issue.] c3p0-0.8.5-pre5 -- added utility class for Oracle users who wish to access vendor specific Connection API relating to BLOBs and CLOBs. [Thanks to Dave Smith for calling attention to this issue.] -- modified ThreadPoolAsynchronousRunner to provide more information should an "apparent deadlock" occur, and fixed that class' recovery strategy from such an event. [Thanks to Damien Evans for calling attention to this issue.] c3p0-0.8.5-pre4 -- added config parameter usesTraditionalReflectiveProxies, which defaults to false, and stitched in the 'new' codegenerated, non-reflective proxy implementation for the default case. c3p0-0.8.5-pre3 -- Added new config parameters breakAfterAcquireFailure, acquireRetryAttempts, and acquireRetryDelay to ComboPoolBackedDataSource (forget to modify this class when I added the params earlier.) -- Added description of raw connection operations to docs. c3p0-0.8.5-pre2 -- Defined AuthMaskedProperties object, and used this to prevent usernames and passwords from being dumped to logs (a security issue). [Thanks to Zac Jacobson for calling attention to this issue.] -- Made BasicResourcePool's refurbishment of checked-in resources asynchronous, and used this to add a test of the resource on check-in. But since the extra test may slow stuff down substantially, I've disabled it pending a testConnectionsOnCheckin config parameter. -- Fixed NullPointerException in C3P0ImplUtils.findAuth(Object o) which occurred when the Object at issue had write-only properties. [Thanks to mrfekson for calling attention to this issue.] -- Added acquireRetryAttempts, acquireRetryDelay, and breakAfterAcquireFailure as configurable properties. Supporting breakAfterAcquireFailure == false required substantial changes to BasicResourcePool. [Thanks to Zac Jacobson for suggesting the behavior for breakAfterAcquireFailure == false.] -- Added poolOwnerIdentityToken property to PoolBackedDataSource, which becomes part of the state of C3P0PooledConectionPoolManager, to avoid possibility that multiple, identically configured pools that users create separately and consider distinct would be closed if any one of them were closed. This parameter ensures that for each user-created DataSource, there will be a distinct C3P0PooledConectionPoolManager. Multiple copies, as often arise via deserialization and/or dereferencing JNDI DataSources, will still share a single pool and configuration. -- Added reset methods, hard and soft, to PooledDataSource and its implementations. Also added some extra aggregate pool statistics methods. [Thanks to Travis Reeder for suggesting the hardReset() behavior.] -- Fixed bug that PoolBackedDataSource always provided statistics for the default authentication pool, even when alternate usernames and passwords were provided. c3p0-0.8.5-pre1 -- Defined the C3P0ProxyConnection interface, and modified both reflective and unreflective proxy Connection code to implement it. The interface provides a method through which advanced users can work with the raw, unproxied database Connection. This was motivated by some Oracle-specific API that could not be passed through the generic Connections returned by c3p0 pools. Thanks to Dave Smith for calling attention to this issue. -- Fixed a NullPointerException that resulted when users called DriverManagerDataSource's getConnection( username, password ) with either username or password as null. Users will now see the SQLException provided by their database for bad authentication, which should make the problem more obvious. c3p0-0.8.4.5 -- Modified all variants of StatementCacheKey, as well as C3P0PooledConnection (proxy Statements) to support jdbc3.0 API for autogenerated keys and ResultSet holdability. All jdbc 3.0 API is now supported. c3p0-0.8.4.2 -- Fixed bug in which proxy Statements and ResultSets returned their naked, unproxied parents from their getConnection() / getStatement() methods. Thanks to Christian Josefsson for noticing this! -- Added check to ensure that ResourcePools are not broken prior to posting asynchronous events. It'd be better to factor the (as yet unutilized async event stuff into a subclass to simplify BasicResourcePool). -- Fixed documentation typo that said default numHelperThreads was "false"... now it's correctly set to "3". -- Added extra System.err information to instrument the causes of broken resource pools. -- finalize() method of BasicResourcePool checks to be sure user has not already closed the pool before closing, to avoid spurious multiple close warnings. Thanks to Gavin King. c3p0-0.8.4.1 -- Added (hopefully not too annoying) dump of DataSource configuration on pool initialization to assist user debugging. -- Added methods to force destroy all resources used by a PooledDataSource, even if other DataSource instances are sharing those resources. This is intended primarily for applications that wish to discard the ClassLoader that loaded c3p0, regardless of whatever's currently going on. -- Turned off annoying trace messages when a C3P0PooledConnection closes. -- Fixed issue in statement cache whereby statements that fail to check-in properly (that throw an exception in "clearParameters") cause an exception in removeStatement, because removeStatement sees a statement that appears neither to be checked-out, nor in the deathmarch for checked-in statements. Resolved by re-adding truculent statement to the checkedOut set, and then destroying using removeStatement's codepath for removing and (force-)destroying checked-out statements. Thanks to Zach Scott for calling attention to this issue. c3p0-0.8.4 -- Updated and HTML-ized documentation, updated READMEs. c3p0-0.8.4-test5 -- Includes, but does not yet use, cleaner, nonreflective reimplementation of C3P0PooledConnection and all of the JDBC proxy wrappers. (c3p0-0.8.4 will stick with the old, tested implementation, c3p0-0.8.5 will replace.) -- Removed temporary debug wrapper around acquired Connections added in c3p0-0.8.4-test4-3. c3p0-0.8.4-test4-3 -- Fixed race condition in BasicResourcePool close(), whereby pooled resources were to be destroyed by an asynchronous thread that itself was shut down by the close() method, so the resource closures did not necessarily occur. Pooled resources are now destroyed synchronously in BasicResourcePool.close() -- Fixed erroneous call to C3P0PooledConnection reset() even when the PooledConnection is known to be broken. -- Added temporary debug wrapper that dumps a stack trace on physical Connection close() to help Adrian track down a stubborn issue. c3p0-0.8.4-test4 -- Made sure PooledConnection's that are known to be broken are not reset() when the ProxyConnection that noticed the break cleans itself up. -- Fixed a problem in C3P0PooledConnection's ProxyConnectionInvocationHandler when Connection-invalidating exceptions occurred inside the factored-out doSilentClose() method rather than in the invoke() method. This could lead to broken PooledConnections not being noticed and expunged from the pool prior to recheck-out. -- Ensured stack-trace of any Connection-invalidating Exceptions are logged. (Previously only the messages were logged.) -- Access to ProxyConnections is now synchronized to avoid a possible race condition where a Connection could close while another method was in progress. -- Cleaned up C3P0PooledConnection a bit, got rid of no longer used reflective code, modified to use new SQL interface filter classes. -- Reorganized bean generation stuff to sit under com.mchange.v2.codegen -- Added com.mchange.v2.sql.filter package, and code generation stuff so that abstract filter classes that implement JDBC interfaces can be easily regenerated from current versions. (This is preparation for JDK 1.4.x build support.) c3p0-0.8.4-test3 -- Reorganized C3P0PooledConnection and C3P0PooledConnectionPool so that PooledConnections only fire connectionErrorOccurred events on errors that signal the Connection is invalid. (Previously we fired the event in all cases, then tested the validity of the connection in the event handler.) -- Fixed a bug where SQLExceptions that do not signal invalid Connections (such as an exception on transaction commit under optimistic concurrency) caused Connections to be closed, but still returned to the pool, leaving the pool corrupt. [Thanks to Adrian Petru Dimulescu for discovering and reporting this subtle problem!] c3p0-0.8.4-test2 -- Backed off a binary incompatible change to DataSources API. Users interested in statistics about running DataSources will need to cast the result of DataSources.pooledDataSource() to a com.mchange.v2.c3p0.PooledDataSource object. Other users should be able to use DataSources without recompilinbg libraries that depend upon it. -- Defined com.mchange.v2.c3p0.ComboPooledDataSource, a single, directly-instantiable JavaBean-style DataSource backed by a c3p0 pool, which makes integration with various app servers easier (e.g. works with Tomcat), and which may provide a more straightforward API for users than DataSources and PoolConfig. c3p0-0.8.4-test1 -- Switched various classes from using RoundRobinAsynchronousRunner to a new ThreadPoolAsynchronousRunner. -- Defined PoolingDataSource interface, which permits clients to access statistics about the state of underlying pools, and made C3P0 pool-backed DataSources implement that interface. -- fixed a subtle bug with respect to ownership of shared resources in which finalize() methods for discarded DataSources could cause helper threads and other resources to be cleaned up prematurely, while they are still in use by other DataSources. -- major reorganization of code generation for DataSources and the resulting objects. -- reorganization of Serializable and Referenceable code of DataSources for JNDI Binding -- made PoolConfig defaults (which are set by system properties, a c3p0.properties file, or else hardcoded defaults) apply to DataSources that are directly instantiated rather than created via the com.mchange.v2.c3p0.DataSources factory class. -- organized scattered stuff into a self-contained, distributable build directly, and divided source and binary distributions -- relicensed library; now available under LGPL. -- THERE ARE SOME MAJOR REORGANIZATIONS IN THIS RELEASE. ANY HELP IN TESTING AND FEEDBACK WOULD BE APPRECIATED! THANKS! c3p0-0.8.3.1 -- take greater care to abort if a helper thread wakes from wait() inside of a broken resource pool -- log more debug information if a pool unexpectedly breaks c3p0-0.8.3 -- resolved a deadlock arising from ConnectionEventSupport objects calling event listener methods while holding the ConnectionEventSupport's lock. (Thanks to an anonymous Sourceforge bug submitter for tracking this down.) -- added two configuration parameters to modify how c3p0 deals with potentially unresolved transactions on transaction close -- autoCommitOnClose and forceIgnoreUnresolvedTransactions. c3p0's default behavior is as it always was (and as I think it nearly always should be) -- by default we roll back any uncommitted work on close. See PoolConfig class for complete documentation. -- fixed stupid build error that made unzipping c3p0 archives messy since c3p0-0.8.2. (SORRY!) c3p0-0.8.3-pre-travis -- fixed problem with c3p0 trying endlessly to connect to a database that is down or not present. c3p0 now tries thirty time, once per second, then gives up. if there's demand, I'll make the delay and number of attempts user configurable. Thanks to Alfonso da Silva for calling attention to this problem. -- modified RoundRobinAsynchronousRunner to die more gracefully if, somehow, one of its CarefulAsynchronousRunners somehow dies. Thanks to Travis Reeder for calling attention to this issue. -- modified ResourcePools to allow resources to be tested periodically and asynchronously while they are idle in the pool. -- added to a new configuration property to PoolConfig and related classes, idleConnectionTestPeriod, which if set to a greater-than-zero value will cause c3p0 to periodically test idle, pooled connection, and remove them from the pool if they are broken. Thanks to Travis Reeder for calling attention to this issue. -- removed SQLState 08S01 from the set of SQL states presumed to mean all connections in the pool have become invalid. Apparently MySQL uses this SQLState to indicate the timing out of idle, individual connections. Thanks to Travis Reeder for calling attention to this issue. -- many (!) bug-fixes, small tweaks and improvements. -- temporarily sprinkled some debugging output prefixed "c3p0-TRAVIS" to try to resolve some issues for Travis Reeder c3p0-0.8.2 -- Addressed a rare problem that ocurred when application servers or other external code calls interrupt() on c3p0 helper threads. Thanks to Travis Reeder for reporting this issue! The endless cascade of ArrayIndexOutOfBoundsException that would occasionallY result has been fixed, and c3p0 helper threads now ignore interupts, which should almost completely prevent such interrupts() from leaving c3p0 pools in a corrupt state. [In the very, very unlikely event that multiple, well-timed interrupts() cause a pool to diagnose itself broken, c3p0 will start throwing clear exceptions to indicate that -- there shouldn't be any deadlock or any subtle kind of corruption.] -- Deprecated PoolBackedDataSourceFactory and DriverManagerDataSourceFactory in favor of the newer DataSources class. -- Updated example code and documentation. -- Moved constants from DataSources to PoolConfig where they belong! c3p0-0.8.2-pre10 -- Removed use of properties default mechanism in setting up JDBC properties for DriverManagerDataSource, as some drivers use get() rather than getProperties(), and the Properties.get() method ignores defaults. [Thanks go to Michael Jakl for both finding and fixing this problem!!!] -- Fixed subtle problem whereby the introspective constructor of C3P0PooledConnectionPoolManager would inadvertently check out an extra pooled connection, by treating the getPooledConnection() as a simple property read and invoking it. [Thanks go to Michael Jakl for both finding and fixing this bug!!!] c3p0-0.8.2-pre9 -- Finished DataSources static factory for, um, DataSources. -- Added PoolConfig class to encapsulate all configuration information from factories -- Set up PoolConfig to pay attention to (in order): 1) explicit, user-defined parameters 2) parameters defined as System properties 3) parameters defined in a Properties file resource, at resource pasth /c3p0.properties in PoolConfig's classloader 4) Hardcoded defaults from the C3P0Defaults class -- Defined a new pool configuration property, "testConnectionOnCheckout". If set to true (it defaults to false), each pooled Connection will be verified at checkout time, before being supplied to clients. THIS SLOWS CONNECTION CHECKOUT DRAMATICALLY (by an order of magnitude on my machine), but some folks may want it. The expensive, verified Connections are still faster to acquire than brand new ones. -- If a Connection experiences an SQLException with a defined SQL State of 08001, 08007, or 08S01, the entire database is considered to have been shutdown, and the pool whose connection experienced the problem is reset -- i.e. all existing Connections are discarded, and new Connections are acquired for the pool. (Thanks! to Gavin King for suggesting the SQL State approach to detecting disconnects.) -- ConnectionTester interface and its default implementation were modified to support reporting DATABASE_IS_INVALID (rather than simply testing a disconnected, individual Connection). c3p0-0.8.2-pre8 -- Fixed some really stupid bugs from pre-7, in particular the static factory methods of the DataSources class were not declared static. Oops. c3p0-0.8.2-pre7 -- Major reorganization of data source implementations. These are now generated from XML templates, because it was becoming difficult to keep multiple versions of multiple types of datasources in sync with one another -- a new factory / utility class has been added, com.mchange.v2.c3p0.DataSources. Soon the older factories (DriverManagerDataSourceFactory and PoolBackedDataSourceFactory) will be deprecated in favor of this. -- Began adding support for wrapper DataSources that lazily bind to an unpooled DataSource specified via JNDI. (Current wrappers require an actual instance, not a mere reference in order to construct a PoolBacked or ConnectionPoolDataSource). c3p0-0.8.2-pre6 -- Fixed bug that led to ConcurrentModificationException when Connection.close() iterates through and closes its unclosed Statements. -- Fixed bug that caused uncached Statements to sometimes be closed twice, as they were not properly removed from the set of Connection-associated statements on user- initiated Statement.close(), and would thus be closed again on Connection.close(). -- Reorganized classes to clean up top-level com.mchange.v2.c3p0 package. The gory innards of c3p0 now live in an impl package. -- Reorganized DataSources so that there are "Base" versions suitable for DBMS-specific subclassing. c3p0-0.8.2-pre5 -- DataSources looked up by JNDI now "coalesce" -- i.e., if two separate calls look-up the same JNDI bound DataSource, they will both see the same DataSource instance in the local VM. This is especially important for PoolBackedDataSources, as they own "helper threads" that help to manage the pool. Now each logical DataSource shares the same pool of helper threads, regardless of whether it is looked up once and cached, or looked up multiple times and at multiple places by an application. -- Number of helper-threads managing a PoolBackedDataSource is now user-configurable c3p0-0.8.2-pre4 -- Fixed BAD memory leak -- cachedStatements were being retained on close. This brings a performance improvement to the StatementCache as well. -- Set-up StatementCacheKey to coalesce, such that its equals method can look like {return (this == o);}. Unfortunately, I did not see the kind of performance increase I'd anticipated from this... in fact, whatever performance changes I did see were pretty negligable. Performed some other, mostly useless, optimizations to the process of acquiring StatementCacheKeys. (I can't decide... I've got 3 usuable, broadly similar versions of StatementCacheKey now.) -- Fixed bugs having to do with when to create and the daemon status of Timers -- Appropriately synchronized access to PoolBackedDataSource. (This should permit me to pull back on synchronization / marking of volatile in some dependent classes, as access to these is now controlled via PoolBackedDataSource.) -- Made instantion of C3P0PooledConnectionPoolManager by WrapperPoolBackedDataSource "lazy", so that Timer / Async task threads are only started up when a Connection is actually requested from a DataSource. This is useful especially for the instance residing in the JNDI server VM, whose purpose is likely only to serve as an instance to be looked up over the network. There's no reason why it should keep several stalled Threads open. -- Fixed DefaultConnectionTester, whose logic was bass-ackwards. c3p0-0.8.2-pre3 -- Factory method for StatementCacheKeys now "coalesce" equivalent instances to conserve memory and to enable a fast (this == o) test to usually work in equals methods. [Value test remains for when identity test fails... maybe later I'll be more comfortable with a 1 instance per value guarantee, and remove the rest of the test. As the constructor is private, the factory method coalesces, and the class is not Serializable, an identity test should suffice. But I'm paranoid.] -- All asynchronous tasks are now distributed to 3 helper threads per DataSource rather than queuing on just one. (Culing of expired Connections is still managed by a single java.util.Timer... I don't think this will be a problem.) c3p0-0.8.2-pre2 -- Total rewite of Statement cache! c3p0-0.9.1.2.orig/src/dist-static/LICENSE0000644000175000017500000006347607736457221015552 0ustar godgod GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

QuickstartGo To Top

c3p0 was designed to be butt-simple to use. Just put the jar file [lib/c3p0-@c3p0.version@.jar] in your application's effective CLASSPATH, and make a DataSource like this:

import com.mchange.v2.c3p0.*; ... ComboPooledDataSource cpds = new ComboPooledDataSource(); cpds.setDriverClass( "org.postgresql.Driver" ); //loads the jdbc driver cpds.setJdbcUrl( "jdbc:postgresql://localhost/testdb" ); cpds.setUser("dbuser"); cpds.setPassword("dbpassword");

[Optional] If you want to turn on PreparedStatement pooling, you must also set maxStatements and/or maxStatementsPerConnection (both default to 0):

cpds.setMaxStatements( 180 );

Do whatever you want with your DataSource, which will be backed by a Connection pool set up with default parameters. You can bind the DataSource to a JNDI name service, or use it directly, as you prefer.

When you are done, you can clean up the DataSource you've created like this:

DataSources.destroy( cpds );

That's it! The rest is detail.

What is c3p0?Go To Top

c3p0 is an easy-to-use library for making traditional JDBC drivers "enterprise-ready" by augmenting them with functionality defined by the jdbc3 spec and the optional extensions to jdbc2. In particular, c3p0 provides several useful services:

  • Classes which adapt traditional DriverManager-based JDBC drivers to the new javax.sql.DataSource scheme for acquiring database Connections.
  • Transparent pooling of Connection and PreparedStatements behind DataSources which can "wrap" around traditional drivers or arbitrary unpooled DataSources.

The library tries hard to get the details right:

  • c3p0 DataSources are both Referenceable and Serializable, and are thus suitable for binding to a wide-variety of JNDI-based naming services.
  • Statement and ResultSets are carefully cleaned up when pooled Connections and Statements are checked in, to prevent resource- exhaustion when clients use the lazy but common resource-management strategy of only cleaning up their Connections....
  • The library adopts the approach defined by the JDBC 2 and 3 specification (even where these conflict with the library author's preferences). DataSources are written in the JavaBean style, offering all the required and most of the optional properties (as well as some non-standard ones), and no-arg constructors. All JDBC-defined internal interfaces are implemented (ConnectionPoolDataSource, PooledConnection, ConnectionEvent-generating Connections, etc.) You can mix c3p0 classes with compliant third-party implementations (although not all c3p0 features will work with external implementations).

c3p0 hopes to provide DataSource implementations more than suitable for use by high-volume "J2EE enterprise applications". Please provide feedback, bug-fixes, etc.!

PrerequisitesGo To Top

c3p0 requires a level 1.3.x or above Java Runtime Environment, and the JDBC 2.x or above javax.sql libraries. c3p0 works fine under Java 1.4.x and 1.5.x as well.

InstallationGo To Top

Put the file lib/c3p0-@c3p0.version@.jar somewhere in your CLASSPATH (or any other place where your application's classloader will find it). That's it!

Using c3p0Go To Top

From a users' perspective, c3p0 simply provides standard jdbc2 DataSource objects. When creating these DataSources, users can control pooling-related, naming-related, and other properties (See Appendix A). All pooling is entirely transparent to users once a DataSource has been created.

There are three ways of acquiring c3p0 pool-backed DataSources: 1) directly instantiate and configure a ComboPooledDataSource bean; 2) use the DataSources factory class; or 3) "build your own" pool-backed DataSource by directly instantiating PoolBackedDataSource and setting its ConectionPoolDataSource. Most users will probably find instantiating ComboPooledDataSource to be the most convenient approach. Once instantiated, c3p0 DataSources can be bound to nearly any JNDI-compliant name service.

Regardless of how you create your DataSource, c3p0 will use defaults for any configuration parameters that you do not specify programmatically. c3p0 has built-in, hard-coded defaults, but you can override these by creating a file called c3p0.properties and storing it as a top-level resource in the same CLASSPATH (or ClassLoader) that loads c3p0's jar file. As of c3p0-0.9.1, you can also supply a file called c3p0-config.xml for more advanced configuration. See Configuration below.

Instantiating and Configuring a ComboPooledDataSource Go To Top

Perhaps the most straightforward way to create a c3p0 pooling DataSource is to instantiate an instance of com.mchange.v2.c3p0.ComboPooledDataSource. This is a JavaBean-style class with a public, no-arg constructor, but before you use the DataSource, you'll have to be sure to set at least the property jdbcUrl. You may also want to set user and password, and if you have not externally preloaded the old-style JDBC driver you'll use you should set the driverClass.

ComboPooledDataSource cpds = new ComboPooledDataSource(); cpds.setDriverClass( "org.postgresql.Driver" ); //loads the jdbc driver cpds.setJdbcUrl( "jdbc:postgresql://localhost/testdb" ); cpds.setUser("swaldman"); cpds.setPassword("test-password"); // the settings below are optional -- c3p0 can work with defaults cpds.setMinPoolSize(5); cpds.setAcquireIncrement(5); cpds.setMaxPoolSize(20); // The DataSource cpds is now a fully configured and usable pooled DataSource ...

The defaults of any c3p0 DataSource are determined by configuration you supply, or else revert to hard-coded defaults [see configuration properties]. c3p0-0.9.1 and above supports multiple, named configurations. If you wish to use a named configuration, construct your com.mchange.v2.c3p0.ComboPooledDataSource with the configuration name as a constructor agument:

ComboPooledDataSource cpds = new ComboPooledDataSource("intergalactoApp");

Of course, you can still override any configuration properties programmatically, as above.

Using the DataSources factory class Go To Top

Alternatively, you can use the static factory class com.mchange.v2.c3p0.DataSources to build unpooled DataSources from traditional JDBC drivers, and to build pooled DataSources from unpooled DataSources:

DataSource ds_unpooled = DataSources.unpooledDataSource("jdbc:postgresql://localhost/testdb", "swaldman", "test-password"); DataSource ds_pooled = DataSources.pooledDataSource( ds_unpooled ); // The DataSource ds_pooled is now a fully configured and usable pooled DataSource. // The DataSource is using a default pool configuration, and Postgres' JDBC driver // is presumed to have already been loaded via the jdbc.drivers system property or an // explicit call to Class.forName("org.postgresql.Driver") elsewhere. ...

If you use the DataSources factory class, and you want to programmatically override default configuration parameters, you can supply a map of override properties:

DataSource ds_unpooled = DataSources.unpooledDataSource("jdbc:postgresql://localhost/testdb", "swaldman", "test-password"); Map overrides = new HashMap(); overrides.put("maxStatements", "200"); //Stringified property values work overrides.put("maxPoolSize", new Integer(50)); //"boxed primitives" also work // create the PooledDataSource using the default configuration and our overrides ds_pooled = DataSources.pooledDataSource( ds_unpooled, overrides ); // The DataSource ds_pooled is now a fully configured and usable pooled DataSource, // with Statement caching enabled for a maximum of up to 200 statements and a maximum // of 50 Connections. ...

If you are using named configurations, you can specify the configuration that defines the default configuration for your DataSource:

// create the PooledDataSource using the a named configuration and specified overrides ds_pooled = DataSources.pooledDataSource( ds_unpooled, "intergalactoAppConfig", overrides );

Show deprecated PoolConfig approach...

RARE: Forcing authentication information, regardless of (mis)configuration of the underlying (unpooled) DataSource

You can wrap any DataSouce using DataSource.pooledDataSource( ... ), usually with no problem whatsoever. DataSources are supposed to indicate the username and password associated by default with Connections via standard properties user and password. Some DataSource implementations do not offer these properties. Usually this is not at all a problem. c3p0 works around this by acquiring "default" Connections from the DataSource if it can't find default authentication information, and a client has not specified the authentification information via getConnection( user, password ).

However, in rare circumstances, non-c3p0 unpooled DataSources provide a user property, but not a password property, or you have access to a DataSource that you wish to wrap behind a pool, but you wish to override its build-in authentification defaults without actually modifying the user or password properties.

c3p0 provides configuation properties overrideDefaultUser and overrideDefaultPassword. If you set these properties, programmatically as above, or via any of c3p0's configuration mechanisms, c3p0 PooledDataSources will ignore the user and password property associated with the underlying DataSource, and use the specified overrides instead.

Querying a PooledDataSource's current status Go To Top

c3p0 DataSources backed by a pool, which include implementations of ComboPooledDataSource and the objects returned by DataSources.pooledDataSource( ... ), all implement the interface com.mchange.v2.c3p0.PooledDataSource, which makes available a number of methods for querying the status of DataSource Connection pools. Below is sample code that queries a DataSource for its status:

// fetch a JNDI-bound DataSource InitialContext ictx = new InitialContext(); DataSource ds = (DataSource) ictx.lookup( "java:comp/env/jdbc/myDataSource" ); // make sure it's a c3p0 PooledDataSource if ( ds instanceof PooledDataSource) { PooledDataSource pds = (PooledDataSource) ds; System.err.println("num_connections: " + pds.getNumConnectionsDefaultUser()); System.err.println("num_busy_connections: " + pds.getNumBusyConnectionsDefaultUser()); System.err.println("num_idle_connections: " + pds.getNumIdleConnectionsDefaultUser()); System.err.println(); } else System.err.println("Not a c3p0 PooledDataSource!");

The status querying methods all come in three overloaded forms, such as:

  • public int getNumConnectionsDefaultUser()
  • public int getNumConnections(String username, String password)
  • public int getNumConnectionsAllUsers()

c3p0 maintains separate pools for Connections with distinct authentications. The various methods let you query the status of pools individually, or aggregate statistics for all authentifications for which your DataSource is maintaining pools. Note that pool configuration parmeters such as maxPoolSize are enforced on a per-authentification basis! For example, if you have set maxPoolSize to 20, and if the DataSource is managing connections under two username-password pairs [the default, and one other pair established via a call to getConnection(user, password), you should expect to see as many as 40 Connections from getNumConnectionsAllUsers().

Most applications only acquire default-authenticated Connections from DataSources, and can typically just use the getXXXDefaultUser() to gather Connection statistics.

As well as Connection pool realted statistics, you can retrieve status information about each DataSource's Thread pool. Please see PooledDataSource for a complete list of available operations.

Using C3P0Registry to get a reference to a DataSource

If it's inconvenient or impossible to get a reference to your DataSource via JNDI or some other means, you can find all live c3p0 DataSources using the C3P0Registry class, which includes three static methods to help you out:

  • public static Set getPooledDataSources()
  • public static Set pooledDataSourcesByName( String dataSourceName )
  • public static PooledDataSource pooledDataSourceByName( String dataSourceName )

The first method will hand you the Set of all live c3p0 PooledDataSources. If you are sure your application only makes one PooledDataSources, or you can distinguish between the DataSources by their configuration properties (inspected via "getters"), the first method may be sufficient. Because this will not always be the case, c3p0 PooledDataSources have a special property called dataSourceName. You can set the dataSourceName property directly when you construct your DataSource, or dataSourceName can be set like any other property in a named or the default config. Otherwise, dataSourceName will default to either 1) the name of your DataSource's configuration, if you constructed it with a named configuration; or 2) a unique (but unpredicatble) name if you are using the default configuration.

There is no guarantee that a dataSourceName will be unique. For example, if two c3p0 DataSources share the same named configuration, and you have not set the dataSourceName programmatically, the two data sources will both share the name of the configuration. To get all of the DataSources with a particular dataSourceName, use pooledDataSourcesByName( ... ). If you've ensured that your DataSource's name is unique (as you will generally want to do, if you intend to use C3P0Registry to find your DataSources), you can use the convenience method pooledDataSourceByName( ... ), which will return your DataSource directly, or null if no DataSource with that name is available. If you use pooledDataSourceByName( ... ) and more than one DataSource shares the name supplied, which one it will return is undefined.

Cleaning up after c3p0 PooledDataSources Go To Top

The easy way to clean up after c3p0-created DataSources is to use the static destroy method defined by the class DataSources. Only PooledDataSources need to be cleaned up, but DataSources.destroy( ... ) does no harm if it is called on an unpooled or non-c3p0 DataSource.

DataSource ds_pooled = null; try { DataSource ds_unpooled = DataSources.unpooledDataSource("jdbc:postgresql://localhost/testdb", "swaldman", "test-password"); ds_pooled = DataSources.pooledDataSource( ds_unpooled ); // do all kinds of stuff with that sweet pooled DataSource... } finally { DataSources.destroy( ds_pooled ); }

Alternatively, c3p0's PooledDataSource interface contains a close() method that you can call when you know you are finished with a DataSource. So, you can cast a c3p0 derived DataSource to a PooledDataSource and close it:

static void cleanup(DataSource ds) throws SQLException { // make sure it's a c3p0 PooledDataSource if ( ds instanceof PooledDataSource) { PooledDataSource pds = (PooledDataSource) ds; pds.close(); } else System.err.println("Not a c3p0 PooledDataSource!"); }

Unreferenced instances of PooledDataSource that are not close()ed by clients close() themselves prior to garbage collection in their finalize() methods. As always, finalization should be considered a backstop and not a prompt or sure approach to resource cleanup.

Advanced: Building your own PoolBackedDataSource Go To Top

There is little reason for most programmers to do this, but you can build a PooledDataSource in a step-by-step way by instantiating and configuring an unpooled DriverManagerDataSource, instantiating a WrapperConnectionPoolDataSource and setting the unpooled DataSource as its nestedDataSource property, and then using that to set the connectionPoolDataSource property of a new PoolBackedDataSource.

This sequence of events is primarily interesting if your driver offers an implementation of ConnectionPoolDataSource, and you'd like c3p0 to use that. Rather than using c3p0's WrapperConnectionPoolDataSource, you can create a PoolBackedDataSource and set its connectionPoolDataSource property. Statement pooling, ConnectionCustomizers, and many c3p0-specific properties are unsupported with third party implementations of ConnectionPoolDataSource. (Third-party DataSource implementations can be substituted for c3p0's DriverManagerDataSource with no significant loss of functionality.)

Advanced: Raw Connection and Statement Operations Go To Top

JDBC drivers sometimes define vendor-specific, non-standard API on Connection and Statement implementations. C3P0 wraps these Objects behind a proxies, so you cannot cast C3P0-returned Connections or Statements to the vendor-specific implementation classes. C3P0 does not provide any means of accessing the raw Connections and Statements directly, because C3P0 needs to keep track of Statements and ResultSets created in order to prevent resource leaks and pool corruption.

C3P0 does provide an API that allows you to invoke non-standard methods reflectively on an underlying Connection. To use it, first cast the returned Connection to a C3P0ProxyConnection. Then call the method rawConnectionOperation, supplying the java.lang.reflect.Method object for the non-standard method you wish to call as an argument. The Method you supply will be invoked on the target you provide on the second argument (null for static methods), and using the arguments you supply in the third argument to that function. For the target, and for any of the method arguments, you can supply the special token C3P0ProxyConnection.RAW_CONNECTION, which will be replaced with the underlying vendor-specific Connection object before the Method is invoked.

C3P0ProxyStatement offers an exactly analogous API.

Any Statements (including Prepared and CallableStatements) and ResultSets returned by raw operations will be c3p0-managed, and will be properly cleaned-up on close() of the parent proxy Connection. Users must take care to clean up any non-standard resources returned by a vendor-specific method.

Here's an example of using Oracle-specific API to call a static method on a raw Connection:

C3P0ProxyConnection castCon = (C3P0ProxyConnection) c3p0DataSource.getConnection(); Method m = CLOB.class.getMethod("createTemporary", new Class[]{Connection.class, boolean.class, int.class}); Object[] args = new Object[] {C3P0ProxyConnection.RAW_CONNECTION, Boolean.valueOf( true ), new Integer( 10 )}; CLOB oracleCLOB = (CLOB) castCon.rawConnectionOperation(m, null, args);

Note: C3P0 now includes special support for some Oracle-specific methods. See Appendix F.

ConfigurationGo To Top

Introduction Go To Top

While c3p0 does not require very much configuration, it is very tweakable. Most of the interesting knobs and dials are represented as JavaBean properties. Following JavaBean conventions, we note that if an Object has a property of type T called foo, it will have methods that look like...

public T getFoo();
public void setFoo(T foo);
...or both, depending upon whether the property is read-only, write-only, or read-writable.

There are several ways to modify c3p0 properties: You can directly alter the property values associated with a particular DataSource in your code, or you can configure c3p0 externally, via a simple Java properties file, via an XML configuration file, or via System properties. Configuration files are normally looked up under standard names (c3p0.properties or c3p0-config.xml) at the top level of an application's classpath, but the XML configuration can be placed anywhere in an application's file system, if the system property com.mchange.v2.c3p0.cfg.xml is set (to an absolute filesystem path).

DataSources are usually configured before they are used, either during or immediately following their construction. c3p0 does support property modifications midstream, however.

If you obtain a DataSource by instantiating a ComboPooledDataSource, configure it by simply calling appropriate setter methods offered by that class before attempting a call to getConnection(). See the example above.

If you obtain a DataSource by using factory methods of the utility class com.mchange.v2.c3p0.DataSources, and wish to use a non-default configuration, you can supply a Map of property names (beginning with lower-case letters) to property values (either as Strings or "boxed" Java primitives like Integer or Boolean).

All tweakable properties are documented for reference in Appendix A. The most basic and important c3p0 configuration topics are discussed below.

Basic Pool Configuration Go To Top

c3p0 Connection pools are very easy to configure via the following basic parameters:

initialPoolSize, minPoolSize, maxPoolSize define the number of Connections that will be pooled. Please ensure that minPoolSize <= maxPoolSize. Unreasonable values of initialPoolSize will be ignored, and minPoolSize will be used instead.

Within the range between minPoolSize and maxPoolSize, the number of Connections in a pool varies according to usage patterns. The number of Connections increases whenever a Connection is requested by a user, no Connections are available, and the pool has not yet reached maxPoolSize in the number of Connections managed. Since Connection acquisition is very slow, it is almost always useful to increase the number of Connections eagerly, in batches, rather than forcing each client to wait for a new Connection to provoke a single acquisition when the load is increasing. acquireIncrement determines how many Connections a c3p0 pool will attempt to acquire when the pool has run out of Connections. (Regardless of acquireIncrement, the pool will never allow maxPoolSize to be exceeded.)

The number of Connections in a pool decreases whenever a pool tests a Connection and finds it to be broken (see Configuring Connection Testing below), or when a Connection is expired by the pool after sitting idle for a period of time, or for being too old (See Managing Pool Size and Connection Age.)

Managing Pool Size and Connection Age Go To Top

Different applications have different needs with regard to trade-offs between performance, footprint, and reliability. C3P0 offers a wide variety of options for controlling how quickly pools that have grown large under load revert to minPoolSize, and whether "old" Connections in the pool should be proactively replaced to maintain their reliablity.

By default, pools will never expire Connections. If you wish Connections to be expired over time in order to maintain "freshness", set maxIdleTime and/or maxConnectionAge. maxIdleTime defines how many seconds a Connection should be permitted to go unused before being culled from the pool. maxConnectionAge forces the pool to cull any Connections that were acquired from the database more than the set number of seconds in the past.

maxIdleTimeExcessConnections is about minimizing the number of Connections held by c3p0 pools when the pool is not under load. By default, c3p0 pools grow under load, but only shrink if Connections fail a Connection test or are expired away via the parameters described above. Some users want their pools to quickly release unnecessary Connections after a spike in usage that forces a large pool size. You can achieve this by setting maxIdleTimeExcessConnections to a value much shorter than maxIdleTime, forcing Connections beyond your set minimum size to be released if they sit idle for more than a short period of time.

Some general advice about all of these timeout parameters: Slow down! The point of Connection pooling is to bear the cost of acquiring a Connection only once, and then to reuse the Connection many, many times. Most databases support Connections that remain open for hours at a time. There's no need to churn through all your Connections every few seconds or minutes. Setting maxConnectionAge or maxIdleTime to 1800 (30 minutes) is quite aggressive. For most databases, several hours may be more appropriate. You can ensure the reliability of your Connections by testing them, rather than by tossing them. (see Configuring Connection Testing.) The only one of these parameters that should generally be set to a few minutes or less is maxIdleTimeExcessConnections.

Configuring Connection Testing Go To Top

c3p0 can be configured to test the Connections that it pools in a variety of ways, to minimize the likelihood that your application will see broken or "stale" Connections. Pooled Connections can go bad for a variety of reasons -- some JDBC drivers intentionally "time-out" long-lasting database Connections; back-end databases or networks sometimes go down "stranding" pooled Connections; and Connections can simply become corrupted over time and use due to resource leaks, driver bugs, or other causes.

c3p0 provides users a great deal of flexibility in testing Connections, via the following configuration parameters:

idleConnectionTestPeriod, testConnectionOnCheckout, and testConnectionOnCheckin control when Connections will be tested. automaticTestTable, connectionTesterClassName, and preferredTestQuery control how they will be tested.

When configuring Connection testing, first try to minimize the cost of each test. By default, Connections are tested by calling the getTables() method on a Connection's associated DatabaseMetaData object. This has the advantage of working with any database, and regardless of the database schema. However, empirically a DatabaseMetaData.getTables() call is often much slower than a simple database query.

The most convenient way to speed up Connection testing is to define the parameter automaticTestTable. Using the name you provide, c3p0 will create an empty table, and make a simple query against it to test the database. Alternatively, if your database schema is fixed prior to your application's use of the database, you can simply define a test query with the preferredTestQuery parameter. Be careful, however. Setting preferredTestQuery will lead to errors as Connection tests fail if the query target table does not exist in your database table prior to initialization of your DataSource.

Advanced users may define any kind of Connection testing they wish, by implementing a ConnectionTester and supplying the fully qualified name of the class as connectionTesterClassName. If you'd like your custom ConnectionTesters to honor and support the preferredTestQuery and automaticTestTable parameters, implement UnifiedConnectionTester, most conveniently by extending AbstractConnectionTester. See the api docs for more information.

The most reliable time to test Connections is on check-out. But this is also the most costly choice from a client-performance perspective. Most applications should work quite reliably using a combination of idleConnectionTestPeriod and testConnectionsOnCheckIn. Both the idle test and the check-in test are performed asynchronously, which leads to better performance, both perceived and actual.

Note that for many applications, high performance is more important than the risk of an occasional database exception. In its default configuration, c3p0 does no Connection testing at all. Setting a fairly long idleConnectionTestPeriod, and not testing on checkout and check-in at all is an excellent, high-performance approach.

Configuring Statement Pooling Go To Top

c3p0 implements transparent PreparedStatement pooling as defined by the JDBC spec. Under some circumstances, statement pooling can dramatically improve application performance. Under other circumstances, the overhead of statement pooling can slightly harm performance. Whether and how much statement pooling will help depends on how much parsing, planning, and optimizing of queries your databases does when the statements are prepared. Databases (and JDBC drivers) vary widely in this respect. It's a good idea to benchmark your application with and without statement pooling to see if and how much it helps.

You configure statement pooling in c3p0 via the following configuration parameters:

maxStatements is JDBC's standard parameter for controlling statement pooling. maxStatements defines the total number PreparedStatements a DataSource will cache. The pool will destroy the least-recently-used PreparedStatement when it hits this limit. This sounds simple, but it's actually a strange approach, because cached statements conceptually belong to individual Connections; they are not global resources. To figure out a size for maxStatements that does not "churn" cached statements, you need to consider the number of frequently used PreparedStatements in your application, and multiply that by the number of Connections you expect in the pool (maxPoolSize in a busy application).

maxStatementsPerConnection is a non-standard configuration parameter that makes a bit more sense conceptually. It defines how many statements each pooled Connection is allowed to own. You can set this to a bit more than the number of PreparedStatements your application frequently uses, to avoid churning.

If either of these parameters are greater than zero, statement pooling will be enabled. If both parameters are greater than zero, both limits will be enforced. If only one is greater than zero, statement pooling will be enabled, but only one limit will be enforced.

Configuring Recovery From Database Outages Go To Top

c3p0 DataSources are designed (and configured by default) to recover from temporary database outages, such as those which occur during a database restart or brief loss of network connectivity. You can affect how c3p0 handles errors in acquiring Connections via the following configurable properties:

When a c3p0 DataSource attempts and fails to acquire a Connection, it will retry up to acquireRetryAttempts times, with a delay of acquireRetryDelay between each attempt. If all attempts fail, any clients waiting for Connections from the DataSource will see an Exception, indicating that a Connection could not be acquired. Note that clients do not see any Exception until a full round of attempts fail, which may be some time after the initial Connection attempt. If acquireRetryAttempts is set to 0, c3p0 will attempt to acquire new Connections indefinitely, and calls to getConnection() may block indefinitely waiting for a successful acquisition.

Once a full round of acquisition attempts fails, there are two possible policies. By default, the c3p0 DataSource will remain active, and will try again to acquire Connections in response to future requests for Connections. If you set breakAfterAcquireFailure to true, the DataSource will consider itself broken after a failed round of Connection attempts, and future client requests will fail immediately.

Note that if a database restart occurs, a pool may contain previously acquired but now stale Connections. By default, these stale Connections will only be detected and purged lazily, when an application attempts to use them, and sees an Exception. Setting maxIdleTime or maxConnectionAge can help speed up the replacement of broken Connections. (See Managing ConnectionAge.) If you wish to avoid application Exceptions entirely, you must adopt a connection testing strategy that is likely to detect stale Connections prior to their delivery to clients. (See "Configuring Connection Testing".) Even with active Connection testing (testConnectionsOnCheckout set to true, or testConnectionsOnCheckin and a short idleConnectionTestPeriod), your application may see occasional Exceptions on database restart, for example if the restart occurs after a Connection to the database has already been checked out.

Managing Connection Lifecycles with Connection Customizer Go To Top

Application frequently wish to set up Connections in some standard, reusable way immediately after Connection acquisitions. Examples of this include setting-up character encodings, or date and time related behavior, using vendor-specific APIs or non-standard SQL statement executions. Occasionally it is useful to override the default values of standard Connection properties such as transactionIsolation, holdability, or readOnly. c3p0 provides a "hook" interface that you can implement, which gives you the opportunity to modify or track Connections just after they are checked out from the database, immediately just prior to being handed to clients on checkout, just prior to being returned to the pool on check-in, and just prior to final destruction by the pool. The Connections handed to ConnectionCustomizers are raw, physical Connections, with all vendor-specific API accessible. See the API docs for ConnectionCustomizer.

To install a ConnectionCustomizer just implement the interface, make your class accessible to c3p0's ClassLoader, and set the configuration parameter below:

ConnectionCustomizers are required to be immutable classes with public no argument constructors. They shouldn't store any state. For (rare) applications that wish to track the behavior of individual DataSources with ConnectionCustomizers, the lifecycle methods each accept a DataSource-specific "identityToken", which is unique to each PooledDataSource.

Below is a sample ConnectionCustomizer. Implementations that do not need to override all four ConnectionCustomizer methods can extend AbstractConnectionCustomizer to inherit no-op implementations of all methods.

import com.mchange.v2.c3p0.*; import java.sql.Connection; public class VerboseConnectionCustomizer { public void onAcquire( Connection c, String pdsIdt ) { System.err.println("Acquired " + c + " [" + pdsIdt + "]"); // override the default transaction isolation of // newly acquired Connections c.setTransactionIsolation( Connection.REPEATABLE_READ ); } public void onDestroy( Connection c, String pdsIdt ) { System.err.println("Destroying " + c + " [" + pdsIdt + "]"); } public void onCheckOut( Connection c, String pdsIdt ) { System.err.println("Checked out " + c + " [" + pdsIdt + "]"); } public void onCheckIn( Connection c, String pdsIdt ) { System.err.println("Checking in " + c + " [" + pdsIdt + "]"); } }

Configuring Unresolved Transaction Handling Go To Top

Connections checked into a pool cannot have any unresolved transactional work associated with them. If users have set autoCommit to false on a Connection, and c3p0 cannot guarantee that there is no pending transactional work, c3p0 must either rollback() or commit() on check-in (when a user calls close()). The JDBC spec is (unforgivably) silent on the question of whether unresolved work should be committed or rolled back on Connection close. By default, c3p0 rolls back unresolved transactional work when a user calls close().

You can adjust this behavior via the following configuration properties:

If you wish c3p0 to allow unresolved transactional work to commit on checkin, set autoCommitOnClose to true. If you wish c3p0 to leave transaction management to you, and neither commit nor rollback (nor modify the state of Connection autoCommit), you may set forceIgnoreUnresolvedTransactions to true. Setting forceIgnoreUnresolvedTransactions is strongly discouraged, because if clients are not careful to commit or rollback themselves prior to close(), or do not set Connection autoCommit consistently, bizarre unreproduceable behavior and database lockups can occur.

Configuring to Debug and Workaround Broken Client Applications Go To Top

Sometimes client applications are sloppy about close()ing all Connections they check out. Eventually, the pool grows to maxPoolSize, and then runs out of Connections, because of these bad clients.

The right way to address this problem is to fix the client application. c3p0 can help you debug, by letting you know where Connections are checked out that occasionally don't get checked in. In rare and unfortunate situations, development of the client application is closed, and even though it is buggy, you cannot fix it. c3p0 can help you work around the broken application, preventing it from exhausting the pool.

The following parameters can help you debug or workaround broken client applications.

unreturnedConnectionTimeout defines a limit (in seconds) to how long a Connection may remain checked out. If set to a nozero value, unreturned, checked-out Connections that exceed this limit will be summarily destroyed, and then replaced in the pool. Obviously, you must take care to set this parameter to a value large enough that all intended operations on checked out Connections have time to complete. You can use this parameter to merely workaround unreliable client apps that fail to close() Connections.

Much better than working-around is fixing. If, in addition to setting unreturnedConnectionTimeout, you set debugUnreturnedConnectionStackTraces to true, then a stack trace will be captured each time a Connection is checked-out. Whenever an unreturned Connection times out, that stack trace will be printed, revealing where a Connection was checked out that was not checked in promptly. debugUnreturnedConnectionStackTraces is intended to be used only for debugging, as capturing a stack trace can slow down Connection check-out.

Other DataSource Configuration Go To Top

See Appendix A for information about the following configuration properties:

numHelperThreads and maxAdministrativeTaskTime help to configure the behavior of DataSource thread pools. By default, each DataSource has only three associated helper threads. If performance seems to drag under heavy load, or if you observe via JMX or direct inspection of a PooledDataSource, that the number of "pending tasks" is usually greater than zero, try increasing numHelperThreads. maxAdministrativeTaskTime may be useful for users experiencing tasks that hang indefinitely and "APPARENT DEADLOCK" messages. (See Appendix A for more.)

checkoutTimeout limits how long a client will wait for a Connection, if all Connections are checked out and one cannot be supplied immediately. usesTraditionalReflectiveProxies, which is of little practical use, permits you to use an old, now superceded implementation of C3P0-generated proxy objects. (C3P0 used to use reflective, dynamic proxies. Now, for enhanced performance, it uses code-generated, nonrefective implementations.) factoryClassLocation can be used to indicate where a URL from which c3p0 classes can be downloaded, if c3p0 DataSources will be retrieved as References from a JNDI DataSource by clients who do not have c3p0 locally installed.

Configuring and Managing c3p0 via JMX Go To Top

If JMX libraries and a JMX MBeanServer are available in your environment (they are include in JDK 1.5 and above), you can inspect and configure your c3p0 datasources via a JMX administration tool (such as jconsole, bundled with jdk 1.5). You will find that c3p0 registers MBeans under com.mchange.v2.c3p0, one with statistics about the library as a whole (called C3P0Registry), and an MBean for each PooledDataSource you deploy. You can view and modify your DataSource's configuration properties, track the activity of Connection, Statement, and Thread pools, and reset pools and DataSources via the PooledDataSource MBean. (You may wish to view the API docs of PooledDataSource for documentation of the available operations.)

If you do not want c3p0 to register MBeans with your JMX environment, you can suppress this behavior with the following, set either as a System property or in c3p0.properties:

com.mchange.v2.c3p0.management.ManagementCoordinator=com.mchange.v2.c3p0.management.NullManagementCoordinator

Configuring Logging Go To Top

c3p0 uses a custom logging library similar to jakarta commons-logging. Log messages can be directed to the popular log4j logging library, to the standard logging facility introduced with jdk1.4, or to System.err. Nearly all configuration should be done at the level of your preferred logging library. There are a very few configuration options specific to c3p0's logging, and usually the defaults will be fine. Logging-related parameters may be placed in your c3p0.properties file, in a file called mchange-log.properties at the top-level of your classpath, or they may be defined as System properties. (The logging properties defined below may not be defined in c3p0-config.xml!) See the box below.

c3p0's logging behavior is affected by certain build-time options. If build-option c3p0.debug is set to false, all messages at a logging level below INFO will be suppressed. Build-option c3p0.trace controls how fine-grained c3p0's below INFO level reporting will be. For the moment, distributed c3p0 binaries are compiled with debug set to true and trace set to its maximum level of 10. But binaries may eventually be distributed with debug set to false. (For the moment, the performance impact of the logging level-checks seems very small, and it's most flexible to compile in all the messages, and let your logging library control which are emitted.) When c3p0 starts up, it emits the build-time values of debug and trace, along with the version and build time.

com.mchange.v2.log.MLog
Determines which library c3p0 will output log messages to. By default, if log4j is available, it will use that library, otherwise if jdk1.4 logging apis are available it will use those, and if neither are available, it will use a simple fallback that logs to System.err. If you want to directly control which library is used, you may set this property to one of:
  • com.mchange.v2.log.log4j.Log4jMLog
  • com.mchange.v2.log.jdk14logging.Jdk14MLog
  • com.mchange.v2.log.FallbackMLog
You may also set this property to a comma separated list of the above alternatives, to define an order of preference among logging libraries.
com.mchange.v2.log.NameTransformer
By default, c3p0 uses very fine-grained logging, in general with one logger for each c3p0 class. For a variety of reasons, some users may prefer fewer, more global loggers. You may opt for one-logger-per-package by setting com.mchange.v2.log.NameTransformer to the value com.mchange.v2.log.PackageNames. Advanced users can also define other strategies for organizing the number and names of loggers by setting this variable to the fully-qualified class name of a custom implementation of the com.mchange.v2.log.NameTransformer interface.
com.mchange.v2.log.FallbackMLog.DEFAULT_CUTOFF_LEVEL
If, whether by choice or by necessity, you are using c3p0's System.err fallback logger, you can use this parameter to control how detailed c3p0's logging should be. Any of the following values (taken from the jdk1.4 logging library) are acceptable:
  • OFF
  • SEVERE
  • WARNING
  • INFO
  • CONFIG
  • FINE
  • FINER
  • FINEST
  • ALL
This property defaults to INFO.

PerformanceGo To Top

Enhanced performance is the purpose of Connection and Statement pooling, and a major goal of the c3p0 library. For most applications, Connection pooling will provide a significant performance gain, especially if you are acquiring an unpooled Connection for each client access. If you are letting a single, shared Connection serve many clients to avoid Connection acquisition overhead, you may suffer performance issues and problems managing transactions when your Connection is under concurrent load; Connection pooling will enable you to switch to a one Connection-per-client model with little or no cost. If you are writing Enterprise Java Beans, you may be tempted to acquire a Connection once and not return it until the bean is about to be destroyed or passivated. But this can be resource-costly, as dormant pooled beans needlessly hold the Connection's network and database resources. Connection pooling permits beans to only "own" a Connection while they are using it.

But, there are performance costs to c3p0 as well. In order to implement automatic cleanup of unclosed ResultSets and Statements when parent resources are returned to pools, all client-visible Connections, ResultSets, Statements are really wrappers around objects provided by an underlying unpooled DataSource or "traditional" JDBC driver. Thus, there is some extra overhead to all JDBC calls.

Some attention has been paid to minimizing the "wrapper" overhead of c3p0. In my environment, the wrapper overhead amounts from several hundreths to several thousandths of the cost of Connection acquisition, so unless you are making many, many JDBC calls in fast succession, there will be a net gain in performance and resource-utilization efficiency. Significantly, the overhead associated with ResultSet operations (where one might iterate through a table with thousands of records) appears to be negligibly small.

Known ShortcomingsGo To Top

  • Connections and Statements are pooled on a per-authentication basis. So, if one pool-backed DataSource is used to acquire Connections both for [user=alice, password=secret1] and [user=bob, password=secret2], there will be two distinct pools, and the DataSource might in the worst case manage twice the number of Connections specified by the maxPoolSize property.

    This fact is a natural consequence of the definition of the DataSource spec (which allows Connections to be acquired with multiple user authentications), and the requirement that all Connections in a single pool be functionally identical. This "issue" will not be changed or fixed. It's noted here just so you understand what's going on.

  • The overhead of Statement pooling is too high. For drivers that do not perform significant preprocessing of PreparedStatements, the pooling overhead outweighs any savings. Statement pooling is thus turned off by default. If your driver does preprocess PreparedStatements, especially if it does so via IPC with the RDBMS, you will probably see a significant performance gain by turning Statement pooling on. (Do this by setting the configuration property maxStatements or maxStatementsPerConnection to a value greater than zero.).

acquireIncrement
Default: 3
Determines how many connections at a time c3p0 will try to acquire when the pool is exhausted. [See "Basic Pool Configuration"]
acquireRetryAttempts
Default: 30
Defines how many times c3p0 will try to acquire a new Connection from the database before giving up. If this value is less than or equal to zero, c3p0 will keep trying to fetch a Connection indefinitely. [See "Configuring Recovery From Database Outages"]
acquireRetryDelay
Default: 1000
Milliseconds, time c3p0 will wait between acquire attempts. [See "Configuring Recovery From Database Outages"]
autoCommitOnClose
Default: false
The JDBC spec is unforgivably silent on what should happen to unresolved, pending transactions on Connection close. C3P0's default policy is to rollback any uncommitted, pending work. (I think this is absolutely, undeniably the right policy, but there is no consensus among JDBC driver vendors.) Setting autoCommitOnClose to true causes uncommitted pending work to be committed, rather than rolled back on Connection close. [Note: Since the spec is absurdly unclear on this question, application authors who wish to avoid bugs and inconsistent behavior should ensure that all transactions are explicitly either committed or rolled-back before close is called.] [See "Configuring Unresolved Transaction Handling"]
automaticTestTable
Default: null
If provided, c3p0 will create an empty table of the specified name, and use queries against that table to test the Connection. If automaticTestTable is provided, c3p0 will generate its own test query, therefore any preferredTestQuery set will be ignored. You should not work with the named table after c3p0 creates it; it should be strictly for c3p0's use in testing your Connection. (If you define your own ConnectionTester, it must implement the QueryConnectionTester interface for this parameter to be useful.) [See "Configuring Connection Testing"]
breakAfterAcquireFailure
Default: false
If true, a pooled DataSource will declare itself broken and be permanently closed if a Connection cannot be obtained from the database after making acquireRetryAttempts to acquire one. If false, failure to obtain a Connection will cause all Threads waiting for the pool to acquire a Connection to throw an Exception, but the DataSource will remain valid, and will attempt to acquire again following a call to getConnection(). [See "Configuring Recovery From Database Outages"]
checkoutTimeout
Default: 0
The number of milliseconds a client calling getConnection() will wait for a Connection to be checked-in or acquired when the pool is exhausted. Zero means wait indefinitely. Setting any positive value will cause the getConnection() call to time-out and break with an SQLException after the specified number of milliseconds.
connectionCustomizerClassName
Default: null
The fully qualified class-name of an implememtation of the ConnectionCustomizer interface, which users can implement to set up Connections when they are acquired from the database, or on check-out, and potentially to clean things up on check-in and Connection destruction. If standard Connection properties (holdability, readOnly, or transactionIsolation) are set in the ConnectionCustomizer's onAcquire() method, these will override the Connection default values.
connectionTesterClassName
Default: com.mchange.v2.c3p0.impl.DefaultConnectionTester
The fully qualified class-name of an implememtation of the ConnectionTester interface, or QueryConnectionTester if you would like instances to have access to a user-configured preferredTestQuery. This can be used to customize how c3p0 DataSources test Connections, but with the introduction of automaticTestTable and preferredTestQuery configuration parameters, "rolling your own" should be overkill for most users. [See "Configuring Connection Testing"]
debugUnreturnedConnectionStackTraces
Default: false
If true, and if unreturnedConnectionTimeout is set to a positive value, then the pool will capture the stack trace (via an Exception) of all Connection checkouts, and the stack traces will be printed when unreturned checked-out Connections timeout. This is intended to debug applications with Connection leaks, that is applications that occasionally fail to return Connections, leading to pool growth, and eventually exhaustion (when the pool hits maxPoolSize with all Connections checked-out and lost). This parameter should only be set while debugging, as capturing the stack trace will slow down every Connection check-out.
Does Not Support Per-User Overrides.
factoryClassLocation
Default: null
DataSources that will be bound by JNDI and use that API's Referenceable interface to store themselves may specify a URL from which the class capable of dereferencing a them may be loaded. If (as is usually the case) the c3p0 libraries will be locally available to the JNDI service, leave this set as null.
Does Not Support Per-User Overrides.
forceIgnoreUnresolvedTransactions
Default: false
Strongly disrecommended. Setting this to true may lead to subtle and bizarre bugs. This is a terrible setting, leave it alone unless absolutely necessary. It is here to workaround broken databases / JDBC drivers that do not properly support transactions, but that allow Connections' autoCommit flags to go to false regardless. If you are using a database that supports transactions "partially" (this is oxymoronic, as the whole point of transactions is to perform operations reliably and completely, but nonetheless such databases are out there), if you feel comfortable ignoring the fact that Connections with autoCommit == false may be in the middle of transactions and may hold locks and other resources, you may turn off c3p0's wise default behavior, which is to protect itself, as well as the usability and consistency of the database, by either rolling back (default) or committing (see c3p0.autoCommitOnClose above) unresolved transactions. This should only be set to true when you are sure you are using a database that allows Connections' autoCommit flag to go to false, but offers no other meaningful support of transactions. Otherwise setting this to true is just a bad idea. [See "Configuring Unresolved Transaction Handling"]
idleConnectionTestPeriod
Default: 0
If this is a number greater than 0, c3p0 will test all idle, pooled but unchecked-out connections, every this number of seconds. [See "Configuring Connection Testing"]
initialPoolSize
Default: 3
Number of Connections a pool will try to acquire upon startup. Should be between minPoolSize and maxPoolSize. [See "Basic Pool Configuration"]
maxAdministrativeTaskTime
Default: 0
Seconds before c3p0's thread pool will try to interrupt an apparently hung task. Rarely useful. Many of c3p0's functions are not performed by client threads, but asynchronously by an internal thread pool. c3p0's asynchrony enhances client performance directly, and minimizes the length of time that critical locks are held by ensuring that slow jdbc operations are performed in non-lock-holding threads. If, however, some of these tasks "hang", that is they neither succeed nor fail with an Exception for a prolonged period of time, c3p0's thread pool can become exhausted and administrative tasks backed up. If the tasks are simply slow, the best way to resolve the problem is to increase the number of threads, via numHelperThreads. But if tasks sometimes hang indefinitely, you can use this parameter to force a call to the task thread's interrupt() method if a task exceeds a set time limit. [c3p0 will eventually recover from hung tasks anyway by signalling an "APPARENT DEADLOCK" (you'll see it as a warning in the logs), replacing the thread pool task threads, and interrupt()ing the original threads. But letting the pool go into APPARENT DEADLOCK and then recover means that for some periods, c3p0's performance will be impaired. So if you're seeing these messages, increasing numHelperThreads and setting maxAdministrativeTaskTime might help. maxAdministrativeTaskTime should be large enough that any resonable attempt to acquire a Connection from the database, to test a Connection, or two destroy a Connection, would be expected to succeed or fail within the time set. Zero (the default) means tasks are never interrupted, which is the best and safest policy under most circumstances. If tasks are just slow, allocate more threads. If tasks are hanging forever, try to figure out why, and maybe setting maxAdministrativeTaskTime can help in the meantime.
Does Not Support Per-User Overrides.
maxConnectionAge
Default: 0
Seconds, effectively a time to live. A Connection older than maxConnectionAge will be destroyed and purged from the pool. This differs from maxIdleTime in that it refers to absolute age. Even a Connection which has not been much idle will be purged from the pool if it exceeds maxConnectionAge. Zero means no maximum absolute age is enforced.
maxIdleTime
Default: 0
Seconds a Connection can remain pooled but unused before being discarded. Zero means idle connections never expire. [See "Basic Pool Configuration"]
maxIdleTimeExcessConnections
Default: 0
Number of seconds that Connections in excess of minPoolSize should be permitted to remain idle in the pool before being culled. Intended for applications that wish to aggressively minimize the number of open Connections, shrinking the pool back towards minPoolSize if, following a spike, the load level diminishes and Connections acquired are no longer needed. If maxIdleTime is set, maxIdleTimeExcessConnections should be smaller if the parameter is to have any effect. Zero means no enforcement, excess Connections are not idled out.
maxPoolSize
Default: 15
Maximum number of Connections a pool will maintain at any given time. [See "Basic Pool Configuration"]
maxStatements
Default: 0
The size of c3p0's global PreparedStatement cache. If both maxStatements and maxStatementsPerConnection are zero, statement caching will not be enabled. If maxStatements is zero but maxStatementsPerConnection is a non-zero value, statement caching will be enabled, but no global limit will be enforced, only the per-connection maximum. maxStatements controls the total number of Statements cached, for all Connections. If set, it should be a fairly large number, as each pooled Connection requires its own, distinct flock of cached statements. As a guide, consider how many distinct PreparedStatements are used frequently in your application, and multiply that number by maxPoolSize to arrive at an appropriate value. Though maxStatements is the JDBC standard parameter for controlling statement caching, users may find c3p0's alternative maxStatementsPerConnection more intuitive to use. [See "Configuring Statement Pooling"]
maxStatementsPerConnection
Default: 0
The number of PreparedStatements c3p0 will cache for a single pooled Connection. If both maxStatements and maxStatementsPerConnection are zero, statement caching will not be enabled. If maxStatementsPerConnection is zero but maxStatements is a non-zero value, statement caching will be enabled, and a global limit enforced, but otherwise no limit will be set on the number of cached statements for a single Connection. If set, maxStatementsPerConnection should be set to about the number distinct PreparedStatements that are used frequently in your application, plus two or three extra so infrequently statements don't force the more common cached statements to be culled. Though maxStatements is the JDBC standard parameter for controlling statement caching, users may find maxStatementsPerConnection more intuitive to use. [See "Configuring Statement Pooling"]
minPoolSize
Default: 3
Minimum number of Connections a pool will maintain at any given time. [See "Basic Pool Configuration"]
numHelperThreads
Default: 3
c3p0 is very asynchronous. Slow JDBC operations are generally performed by helper threads that don't hold contended locks. Spreading these operations over multiple threads can significantly improve performance by allowing multiple operations to be performed simultaneously.
Does Not Support Per-User Overrides.
overrideDefaultUser
Default: null
Forces the username that should by PooledDataSources when a user calls the default getConnection() method. This is primarily useful when applications are pooling Connections from a non-c3p0 unpooled DataSource. Applications that use ComboPooledDataSource, or that wrap any c3p0-implemented unpooled DataSource can use the simple user property.
Does Not Support Per-User Overrides.
overrideDefaultPassword
Default: null
Forces the password that should by PooledDataSources when a user calls the default getConnection() method. This is primarily useful when applications are pooling Connections from a non-c3p0 unpooled DataSource. Applications that use ComboPooledDataSource, or that wrap any c3p0-implemented unpooled DataSource can use the simple password property.
Does Not Support Per-User Overrides.
password
Default: null
For applications using ComboPooledDataSource or any c3p0-implemented unpooled DataSources — DriverManagerDataSource or the DataSource returned by DataSources.unpooledDataSource( ... ) — defines the password that will be used for the DataSource's default getConnection() method. (See also user.)
Does Not Support Per-User Overrides.
preferredTestQuery
Default: null
Defines the query that will be executed for all connection tests, if the default ConnectionTester (or some other implementation of QueryConnectionTester, or better yet FullQueryConnectionTester) is being used. Defining a preferredTestQuery that will execute quickly in your database may dramatically speed up Connection tests. (If no preferredTestQuery is set, the default ConnectionTester executes a getTables() call on the Connection's DatabaseMetaData. Depending on your database, this may execute more slowly than a "normal" database query.) NOTE: The table against which your preferredTestQuery will be run must exist in the database schema prior to your initialization of your DataSource. If your application defines its own schema, try automaticTestTable instead. [See "Configuring Connection Testing"]
propertyCycle
Default: 0
Maximum time in seconds before user configuration constraints are enforced. Determines how frequently maxConnectionAge, maxIdleTime, maxIdleTimeExcessConnections, unreturnedConnectionTimeout are enforced. c3p0 periodically checks the age of Connections to see whether they've timed out. This parameter determines the period. Zero means automatic: A suitable period will be determined by c3p0. [You can call getEffectivePropertyCycle...() methods on a c3p0 PooledDataSource to find the period automatically chosen.]
testConnectionOnCheckin
Default: false
If true, an operation will be performed asynchronously at every connection checkin to verify that the connection is valid. Use in combination with idleConnectionTestPeriod for quite reliable, always asynchronous Connection testing. Also, setting an automaticTestTable or preferredTestQuery will usually speed up all connection tests. [See "Configuring Connection Testing"]
testConnectionOnCheckout
Default: false
Use only if necessary. Expensive. If true, an operation will be performed at every connection checkout to verify that the connection is valid. Better choice: verify connections periodically using idleConnectionTestPeriod. Also, setting an automaticTestTable or preferredTestQuery will usually speed up all connection tests. [See "Configuring Connection Testing"]
unreturnedConnectionTimeout
Default: 0
Seconds. If set, if an application checks out but then fails to check-in [i.e. close()] a Connection within the specified period of time, the pool will unceremoniously destroy() the Connection. This permits applications with occasional Connection leaks to survive, rather than eventually exhausting the Connection pool. And that's a shame. Zero means no timeout, applications are expected to close() their own Connections. Obviously, if a non-zero value is set, it should be to a value longer than any Connection should reasonably be checked-out. Otherwise, the pool will occasionally kill Connections in active use, which is bad. This is basically a bad idea, but it's a commonly requested feature. Fix your $%!@% applications so they don't leak Connections! Use this temporarily in combination with debugUnreturnedConnectionStackTraces to figure out where Connections are being checked-out that don't make it back into the pool!
user
Default: null
For applications using ComboPooledDataSource or any c3p0-implemented unpooled DataSources — DriverManagerDataSource or the DataSource returned by DataSources.unpooledDataSource() — defines the username that will be used for the DataSource's default getConnection() method. (See also password.)
Does Not Support Per-User Overrides.
usesTraditionalReflectiveProxies
Default: false
c3p0 originally used reflective dynamic proxies for implementations of Connections and other JDBC interfaces. As of c3p0-0.8.5, non-reflective, code-generated implementations are used instead. As this was a major change, and the old codebase had been extensively used and tested, this parameter was added to allow users to revert of they had problems. The new, non-reflexive implementation is faster, and has now been widely deployed and tested, so it is unlikely that this parameter will be useful. Both the old reflective and newer non-reflective codebases are being maintained, but support for the older codebase may (or may not) be dropped in the future.

Other Properties Go To Top

The following configuration properties affect the behavior of the c3p0 library as a whole. They may be set as system properties, or in a c3p0.properties file.

Locating Configuration Information

Normally, c3p0's configuration information is placed in a either a c3p0-config.xml or c3p0.properties file at the top-level of an application's CLASSPATH. However, if you wish to place configuration information elsewhere, you may place c3p0 configuration information (in the XML file format only!) anywhere you'd like in the filesystem visible to your application. Just set the following property to the full, absolute path of the XML config file:

  • com.mchange.v2.c3p0.cfg.xml

Logging-related properties

The following properties affect c3p0's logging behavior. Please see Configuring Logging above for specific information.

  • com.mchange.v2.log.MLog
  • com.mchange.v2.log.NameTransformer
  • com.mchange.v2.log.FallbackMLog.DEFAULT_CUTOFF_LEVEL

Configuring JMX

The following property controls c3p0's JMX management interface. Plese see Configuring and Managing c3p0 via JMX above for more information.

  • com.mchange.v2.c3p0.management.ManagementCoordinator

Configuring the VMID

Is it better to be beautiful or correct? Beginning with c3p0-0.9.1, c3p0 opts somewhat reluctantly for correctness.

Here's the deal. Every c3p0 DataSource is allocated a unique "identity token", which is used to ensure that multiple JNDI lookups of the same PooledDataSource always return the same instance, even if the JNDI name-server stores a Serialized or Referenced instance. Previously, c3p0 was happy for generated IDs to be unique within a single VM (and it didn't even get that quite right, before c3p0-0.9.1). But in theory, one VM might look up two different DataSources, generated by two different VMs, that by unlikely coincidence have the same "identity token", leading to errors as one of the two DataSources sneakily substitutes for the second. Though this hypothetical issue has never been reported in practice, c3p0 resolves it by prepending a VMID to its identity tokens. This makes them long and ugly, but correct.

If you don't like the long and ugly VMID, you can set your own, or you can turn off this solution to a hypothetical non-problem entirely with the following property:

  • com.mchange.v2.c3p0.VMID

Set it to NONE to turn off the VMID, set it to AUTO to let c3p0 generate a VMID, or provide any other String to set the VMID that will be used directly. The default is AUTO.

Experimental properties

c3p0-0.9.1 includes a new implementation of asynchronous Connection acquisition that should improve c3p0's performance and resource utilization in cases where database acquisition attempts, for whatever reason, occasionally fail. The new implementation should be significantly better than the "traditional" Connection acquisition strategy, but was added too late in the c3p0-0.9.1 development cycle to be fully tested and enabled by default. Users are encouraged to try the new implementation, both because it is better, and to help iron out any unanticipated problems.

For a full description of the new implementation and the resource bottleneck it is designed to overcome, please see the CHANGELOG entry for c3p0-0.9.1-pre11. To enable the new implementation, set the following parameter to "true".

  • com.mchange.v2.resourcepool.experimental.useScatteredAcquireTask

This feature is expected to be enabled by default in c3p0-0.9.2 and above.

Appendix B: Configuration Files, etc. Go To Top

c3p0 configuration parameters can be set directly in Java code, via a simple Java properties file, via an XML configuration file, or via System properties. Any which way works (the the XML configuration is most powerful, though, as it supports multiple named configurations and per-user overrides. Choose whatever works best for you.

Overriding c3p0 defaults via c3p0.properties Go To Top

To override the library's built-in defaults, create a file called c3p0.properties and place it at the "root" of your classpath or classloader. For a typical standalone application, that means place the file in a directory named in your CLASSPATH environment variable. For a typical web-application, the file should be placed in WEB-INF/classes. In general, the file must be available as a classloader resource under the name /c3p0.properties, in the classloader that loaded c3p0's jar file. Review the API docs (especilly getResource... methods) of java.lang.Class, java.lang.ClassLoader, and java.util.ResourceBundle if this is unfamiliar.

The format of c3p0.properties should be a normal Java Properties file format, whose keys are c3p0 configurable properties. See Appendix A. for the specifics. An example c3p0.properties file is produced below:

# turn on statement pooling c3p0.maxStatements=150 # close pooled Connections that go unused for # more than half an hour c3p0.maxIdleTime=1800

Overriding c3p0 defaults with a System properties Go To Top

c3p0 properties can also be defined as System properties, using the same "c3p0." prefix for properties specified in a c3p0.properties file.

swaldman% java -Dc3p0.maxStatements=150 -Dc3p0.maxIdleTime=1800 example.MyC3P0App

System properties override settings in c3p0.properties. Please see Precedence of Configuration Settings for more information.

Named and Per-User configuration: Overriding c3p0 defaults via c3p0-config.xml Go To Top

As of c3p0-0.9.1, you can define multiple configurations in an XML configuration file, and specify in your code which configuration to use. For any configurations (including the unnamed default configuration), you can define overrides for a particular database user. For example, if several applications access your database under different authentication credentials, you might define maxPoolSize to be 100 for user highVolumeApp, but only 10 for user lowLoadApp. (Recall that Connections associated with different authentication credentials are of necessity separated into separate pools, so it makes sense that these could be configured separately.)

You can use the XML config file for all c3p0 configuration, including configuration of defaults. However, for users who don't want or need the extra complexity, the c3p0.properties file will continue to be supported.

By default, c3p0 will look for an XML configuration file in its classloader's resource path under the name "/c3p0-config.xml". That means the XML file should be placed in a directly or jar file directly named in your applications CLASSPATH, in WEB-INF/classes, or some similar location.

If you prefer not to bundle your configuration with your code, you can specify an ordinary filesystem location for c3p0's configuration file via the system property com.mchange.v2.c3p0.cfg.xml.

Here is an example c3p0-config.xml file:

<c3p0-config> <default-config> <property name="automaticTestTable">con_test</property> <property name="checkoutTimeout">30000</property> <property name="idleConnectionTestPeriod">30</property> <property name="initialPoolSize">10</property> <property name="maxIdleTime">30</property> <property name="maxPoolSize">100</property> <property name="minPoolSize">10</property> <property name="maxStatements">200</property> <user-overrides user="test-user"> <property name="maxPoolSize">10</property> <property name="minPoolSize">1</property> <property name="maxStatements">0</property> </user-overrides> </default-config> <!-- This app is massive! --> <named-config name="intergalactoApp"> <property name="acquireIncrement">50</property> <property name="initialPoolSize">100</property> <property name="minPoolSize">50</property> <property name="maxPoolSize">1000</property> <!-- intergalactoApp adopts a different approach to configuring statement caching --> <property name="maxStatements">0</property> <property name="maxStatementsPerConnection">5</property> <!-- he's important, but there's only one of him --> <user-overrides user="master-of-the-universe"> <property name="acquireIncrement">1</property> <property name="initialPoolSize">1</property> <property name="minPoolSize">1</property> <property name="maxPoolSize">5</property> <property name="maxStatementsPerConnection">50</property> </user-overrides> </named-config> </c3p0-config>

To use a named configuration, you specify the config name when creating your DataSource. For example, using ComboPooledDataSource:

ComboPooledDataSource cpds = new ComboPooledDataSource("intergalactoApp");

Or using the DataSources factory class:

DataSource ds_pooled = DataSources.pooledDataSource( ds_unpooled, "intergalactoApp" );

Precedence of Configuration Settings Go To Top

c3p0 now permits configuration parameters to be set in a number of different ways and places. Fortunately, there is a clear order of precedence that determines which configuration will "take" in the event of conflicting settings. Conceptually, c3p0 goes down this list from top to bottom, using the first setting it finds.

Most applications will never use per-user or named configurations. For these applications, we present a simplified precedence hierarchy:

  1. Configuration values programmatically set.
  2. System property setting of configuration value.
  3. Configuration values taken from the default configuration of a c3p0-config.xml file.
  4. Configuration values specified in a c3p0.properties file
  5. c3p0's hard-coded default values.

For applications that do use named and per-user configurations, here is the complete, normative precedence hierarchy:

  1. User-specific overrides programmatically set via: Note that programmatically setting user-specific overrides replaces all user-specific configuration taken from other sources. If you want to merge programmatic changes with preconfigured overrides, you'll have to use getUserOverridesAsString() and modify the original settings before replacing.
  2. User-specific overrides taken from a DataSource's named configuration (specified in c3p0-config.xml)
  3. User-specific overrides taken from the default configuration (specified in c3p0-config.xml)
  4. Non-user-specific values programmatically set.
  5. Non-user-specific values taken from a DataSource's named configuration (specified in c3p0-config.xml)
  6. System property setting of configuration value.
  7. Non-user-specific values taken from the default configuration (specified in c3p0-config.xml)
  8. Values specified in a c3p0.properties file
  9. c3p0's hard-coded default values.

Appendix C: Hibernate-specific notes Go To Top

Hibernate's C3P0ConnectionProvider explicitly sets 7 c3p0 configuration properties, based on your hibernate configuration, overriding any configuration you may have set in a c3p0.properties file. If you are using Hibernate's C3P0ConnectionProvider you must set the following properties in your hibernate configuration, using hibernate-specific configuration keys. All other properties must be defined as usual in a c3p0.properties file. This is confusing, and will hopefully be simplified some time in the future, but for now...

The following properties must be set in your hibernate configuration:

c3p0-native property namehibernate configuration key
c3p0.acquireIncrementhibernate.c3p0.acquire_increment
c3p0.idleConnectionTestPeriodhibernate.c3p0.idle_test_period
c3p0.initialPoolSizenot available -- uses minimum size
c3p0.maxIdleTimehibernate.c3p0.timeout
c3p0.maxPoolSizehibernate.c3p0.max_size
c3p0.maxStatementshibernate.c3p0.max_statements
c3p0.minPoolSizehibernate.c3p0.min_size
c3p0.testConnectionsOnCheckout hibernate.c3p0.validate hibernate 2.x only!

Remember -- these, and only these, properties must be defined in your hibernate configuration, or else they will be set to hibernate-specified defaults. All other configuration properties that you wish to set should be defined in a c3p0.properties file. (See "Overriding c3p0 defaults via c3p0.properties".)

Appendix D: Configuring c3p0 DataSources in TomcatGo To Top

You can easily configure Apache's Tomcat web application server to use c3p0 pooled DataSources. Below is a Tomcat 5.0 sample config to get you started. It's a fragment of Tomcat's conf/server.xml file, which should be modified to suit and placed inside a <Context> element.

<Resource name="jdbc/pooledDS" auth="Container" type="com.mchange.v2.c3p0.ComboPooledDataSource" /> <ResourceParams name="jdbc/pooledDS"> <parameter> <name>factory</name> <value>org.apache.naming.factory.BeanFactory</value> </parameter> <parameter> <name>driverClass</name> <value>org.postgresql.Driver</value> </parameter> <parameter> <name>jdbcUrl</name> <value>jdbc:postgresql://localhost/c3p0-test</value> </parameter> <parameter> <name>user</name> <value>swaldman</value> </parameter> <parameter> <name>password</name> <value>test</value> </parameter> <parameter> <name>minPoolSize</name> <value>5</value> </parameter> <parameter> <name>maxPoolSize</name> <value>15</value> </parameter> <parameter> <name>acquireIncrement</name> <value>5</value> </parameter> </ResourceParams>

For Tomcat 5.5, try something like the following (thanks to Carl F. Hall for the sample!):

<Resource auth="Container" description="DB Connection" driverClass="com.mysql.jdbc.Driver" maxPoolSize="4" minPoolSize="2" acquireIncrement="1" name="jdbc/TestDB" user="test" password="ready2go" factory="org.apache.naming.factory.BeanFactory" type="com.mchange.v2.c3p0.ComboPooledDataSource" jdbcUrl="jdbc:mysql://localhost:3306/test?autoReconnect=true" />

The rest is standard J2EE stuff: You'll need to declare your DataSource reference in your web.xml file:

<resource-ref> <res-ref-name>jdbc/pooledDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref>

And you can access your DataSource from code within your web application like this:

InitialContext ic = new InitialContext(); DataSource ds = (DataSource) ic.lookup("java:comp/env/jdbc/pooledDS");

That's it!

Appendix E: JBoss-specific notesGo To Top

To use c3p0 with JBoss:

  1. Place c3p0's jar file in the lib directory of your jboss server instance (e.g. ${JBOSS_HOME}/server/default/lib)
  2. Modify the file below, and save it as c3p0-service.xml in the deploy directory of your jboss server (e.g. ${JBOSS_HOME}/server/default/deploy). Note that parameters must be capitalized in this file, but otherwise they are defined as described above.

Please note: As of c3p0-0.9.1, the class name of the jboss configuration mbean has changed to com.mchange.v2.c3p0.jboss.C3P0PooledDataSource (from com.mchange.v2.c3p0.mbean.C3P0PooledDataSource), in order to distinguish what is really jboss-specific functionality from c3p0's more general JMX support.

The old jboss config mbeans are deprecated, but will still work. However, support for new configuration parameters will only be added under the new name. Updating requires a one-word change to your c3p0-service.xml, change "mbean" to "jboss" where your old file says 'code="com.mchange.v2.c3p0.mbean.C3P0PooledDataSource"'. Just do it!

Appendix F: Oracle-specific API: createTemporaryBLOB() and createTemporaryCLOB()Go To Top

The Oracle thin JDBC driver provides a non-standard API for creating temporary BLOBs and CLOBs that requires users to call methods on the raw, Oracle-specific Connection implementation.

Building c3p0 should be as easy as editing build.properties and typing ant. Please send any feedback / questions to Steve Waldman All of the test related properties are very optional. There are various test tasks in the build file, but they are ad-hoc and unsupported. Someday I plan to get with jUnit and do real testing, but that day has not yet come. Until then, you, my dear user, are my primary testing engine. Sorry.
