  oracle.ucp.jdbc.PoolDataSourceImpl
      oracle.ucp.jdbc.PoolXADataSourceImpl

All Implemented Interfaces:

java.io.Serializable, java.sql.Wrapper, javax.naming.Referenceable, javax.naming.spi.ObjectFactory, javax.sql.CommonDataSource, javax.sql.DataSource, javax.sql.XADataSource, PoolDataSource, PoolXADataSource, UniversalConnectionPoolAdapter

public class PoolXADataSourceImpl
extends PoolDataSourceImpl
implements PoolXADataSource, java.io.Serializable, javax.naming.Referenceable, javax.naming.spi.ObjectFactory, UniversalConnectionPoolAdapter

A connection pool-aware data source. This DataSource uses the Universal Connection Pool to get an XAconneciton, creating a proxy to that connection, and returning the proxy to the client. When the client calls close on the XAConnection proxy, the underlying physical connection is usually returned to the pool. Also see the proxy factory.

Besides other data source properties, applications must set the connection factory class name. The connection factory class is a class that implements javax.sql.XADataSource and does not implement its own connection pooling. The connection factory's getXAConnection(...) methods should return a physical XAConnection to the database. For example, "oracle.jdbc.xa.client.OracleXADataSource" is a valid connection factory class name.
