Java/Connection pooling

Java Connection Pooling

enables ODBC applications to reuse a connection from a pool of connections, without having to perform the complete connection process

share environment (henv?)

"Implicitly setting the ADO ActiveConnection (Conn) to a connection string defeats efficiencies from connection pooling, one the new features introduced in ODBC driver manager 3.0. Connection pooling enables an ODBC application to reuse a connection from a pool of connections. Once a connection has been created and placed in the pool, an ODBC application can reuse the same driver and the connection within the same shared environment (henv) without performing the complete connection process."
