Apache Commons DBCP stands for Apache Commons DataBase Connection Pooling.

This package implements the vaunted connection pooling technique, a system to allow the caching of database connections, so users won't need to reconnect to the database every time they need to interact with its data.

This saves up database server resources and improves the DB's responsiveness.

Connection pooling is a technique for relational databases and the Apache Commons DBCP package should work with any relational database the JDBC works with.

What is new in this release:

  • This is a bug fix release.

  • This is a bug fix release.

What is new in version 2.0:

  • Expose the new Pool 2 property evictionPolicyClassName to enable more sophisticated eviction strategies to be used.
  • Added support for pooling PreparedStatements that use auto-generated keys.
  • Enable DBCP to work with a SecurityManager such that only DBCP needs to be granted the necessary permissions to communicate with the database.
  • Provide an option to control if autoCommit is always set to true when a connection is returned to the connection pool.
  • Provide an option to control if rollback is called when a connection is returned to the poll with autoCommit disabled.
  • Provide an option to set the default query timeout.
  • Added support for validation testing database connections on creation.

What is new in version 1.2.2:

  • Use an API specific exception for logging abandoned objects to make scanning the logs for these exceptions simpler and to provide a better message that includes the creation time of the abandoned object.
  • Ensure Statement.getGeneratedKeys() works correctly with the CPDS adapter.
  • Make the class loader used to load the JDBC driver configurable for the BasicDatasource.
  • Handle user password changes for InstanceKeyDataSources.
  • Eliminated direct System.out calls in AbandonedTrace.
