Class DBCPConnectionProvider
java.lang.Object
com.xpn.xwiki.store.DBCPConnectionProvider
- All Implemented Interfaces:
- org.hibernate.connection.ConnectionProvider
public class DBCPConnectionProvider
- extends Object
- implements org.hibernate.connection.ConnectionProvider
A connection provider that uses an Apache commons DBCP connection pool.
To use this connection provider set:
hibernate.connection.provider_class org.hibernate.connection.DBCPConnectionProvider
Supported Hibernate properties:
hibernate.connection.driver_class
hibernate.connection.url
hibernate.connection.username
hibernate.connection.password
hibernate.connection.isolation
hibernate.connection.autocommit
hibernate.connection.pool_size
hibernate.connection (JDBC driver properties)
All DBCP properties are also supported by using the hibernate.dbcp prefix. A complete list can be found on the DBCP
configuration page: http://jakarta.apache.org/commons
/dbcp/configuration.html.
Example:
hibernate.connection.provider_class org.hibernate.connection.DBCPConnectionProvider
hibernate.connection.driver_class org.hsqldb.jdbcDriver
hibernate.connection.username sa
hibernate.connection.password
hibernate.connection.url jdbc:hsqldb:test
hibernate.connection.pool_size 20
hibernate.dbcp.initialSize 10
hibernate.dbcp.maxWait 3000
hibernate.dbcp.validationQuery select 1 from dual
More information about configuring/using DBCP can be found on the DBCP website. There you will also find the DBCP wiki, mailing
lists, issue tracking and other support facilities

supportsAggressiveRelease
public boolean supportsAggressiveRelease()
- Does this connection provider support aggressive release of JDBC connections and re-acquistion of those
connections (if need be) later?
This is used in conjunction with
Environment.RELEASE_CONNECTIONS
to aggressively
release JDBC connections. However, the configured ConnectionProvider must support re-acquisition of the same
underlying connection for that semantic to work.
Typically, this is only true in managed environments where a container tracks connections by transaction or
thread.
