C3P0 ORACLE DRIVER DOWNLOAD

All pooling is entirely transparent to users once a DataSource has been created. Performing the expensive default Connection test on every client checkout will harm client performance. For a variety of reasons, some users may prefer fewer, more global loggers. Please see Precedence of Configuration Settings for more information. Please provide feedback, bug-fixes, etc!

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 DataSourcesyou can use the convenience method pooledDataSourceByName See Locating Configuration Information. Oracke you want to do something totally different, you can implement your own DefaultConnectionTester. Programmatic configuration via PoolConfig If you use the DataSources factory class, and you want to programmatically override default configuration parameters, make use of the PoolConfig class: Even a Connection which has not been much idle will be purged from the pool if it exceeds maxConnectionAge.

It’s a good idea to benchmark your orracle with and without statement pooling to see if and how much it helps. 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. If provided, c3p0 will create an empty table of the specified name, and use queries against that table to test the Connection. For applications that do use named and per-user configurations, here is the complete, normative precedence hierarchy:.

Stack Overflow works best with JavaScript enabled. To return to the original slower but more informative approach, explicitly set the property to false.

You can set any c3p0 properties in your hibernate config using the prefix hibernate. ResourceBundle if this is unfamiliar.

Non-user-specific values taken from a DataSource’s named configuration specified in c3p0-config. They may be set as system properties, in a c3p0. Locating Configuration Information Normally, c3p0’s configuration information is placed in a either a c3p0-config.

Enhanced performance is the purpose of Connection and Statement pooling, and a major goal of the c3p0 library. To find the extensions defined for a PooledDataSourceyou must have access to its identityTokenwhich is supplied as an argument to all ConnectionCustomizer methods.

You can also use this property to specify an alternative location in the ClassLoader resource path, e. C3P0’s default policy is to rollback any uncommitted, pending work. DataSourcesand wish to use a non-default configuration, you can supply a Map oracls property names beginning with lower-case letters to property values either as Strings or “boxed” Java primitives like Integer or Boolean.

This sequence of events is primarily interesting if your driver offers an implementation of ConnectionPoolDataSource, and you’d like c3p0 to use that. Really, you should almost never bother to set this property. Setting this parameter to true causes c3p0 to ignore DriverManager and simply instantiate driverClass directly. Any which way works the the XML configuration is most powerful, though, as it supports multiple named configurations and per-user overrides.

In order to implement automatic cleanup of unclosed ResultSets and Statements when parent resources are returned to pools, all client-visible ConnectionsResultSetsStatements are really wrappers around objects provided by an underlying unpooled DataSource or “traditional” JDBC driver. Instantiating and Oeacle a ComboPooledDataSource Perhaps the most straightforward way to create a c3p0 pooling DataSource is to instantiate an instance of com.

This may not be the most recent version of c3p0. Well, i have found this documentation http: The default is AUTO. Connections and Statements are pooled on a per-authentication basis. A c3p0 pool typically uses just one ConnectionTester to test all of its Connections, oraclr concurrently. It defines how many statements each pooled Connection is allowed to own.

If tasks are hanging forever, try to figure out why, and maybe setting maxAdministrativeTaskTime can help in the meantime. However, if your driver does not support this new-ish API, c3p0’s default behavior is to test Connections by calling the getTables method on a Connection’s associated X3p0 object. Set this to true so that c3p0’s Threads use the the c3p0 library’s AccessControlContextrather than an AccessControlContext that may be associated with the client application and prevent its garbage collection.
