Class PoolDataSourceImpl

java.lang.Object
oracle.ucp.jdbc.PoolDataSourceImpl

All Implemented Interfaces:

java.io.Serializable, javax.naming.Referenceable, javax.naming.spi.ObjectFactory, javax.sql.DataSource, PoolDataSource, UniversalConnectionPoolAdapter

Direct Known Subclasses:

PoolXADataSourceImpl

public class PoolDataSourceImpl

extends java.lang.Object

implements PoolDataSource, 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 a connection, creating a proxy to that connection, and returning the proxy to the client. When the client calls close on the connection proxy, the underlying physical connection is returned to the pool. <p/> Besides other data source properties, applications must set the connection factory class name. The connection factory class is a class that implements javax.sql.DataSource and does not implement its own connection pooling. The connection factory's getConnection(...) methods should return a physical JDBC connection to the database. For example, "oracle.jdbc.pool.OracleDataSource" is a valid connection factory class name.
