Release notes for Commons-DBCP 1.2

NOTE: DBCP v1.2 requires Pool v1.2, make sure you use the correct version!

There were some new features were added since the 1.1 release on 20 October 2003.

• Performance optimizations for the PoolableConnectionFactory of BasicDataSource.


• Add BasicDataSourceFactory.createDataSource(Properties properties) for creating a BasicDataSource.


• Add initialSize parameter to do pre-loading of the connection.


• Refactoring of the DelegatingStatement classes.


• Make some properties dynamic (changeable at runtime), this will be completed in next release.


• Improvements to the prepared statement pooling.


• Driver specific changes/optimizations for: Oracle, Informix, DaffodilDB.


• Several fixes for PerUserPoolDataSource


• PoolingDriver uses now a PoolGuardConnectionWrapper by default. If access to the underlying connection is needed, you have to enable it: PoolingDriver.setAccessToUnderlyingConnectionAllowed(true)


• The following issues were resolved since v1.1: (see Bugzilla for complete description)
