When client applications subsequently invoke Connection#close() to return these connections to the pool, the underlying JDBC connections are closed. Attempts to acquire connections using #getConnection() after this method has been invoked result in Database Connection Pool API. Overview in Dialog Form.

1) Basicdatasource is configured in the code, the code is as follows Connections that are checked out to clients when this method is invoked are not affected. When client applications subsequently invoke Connection#close() to return these connections to the pool, the underlying JDBC connections are closed. Attempts to acquire connections using #getConnection() after this method has been invoked result in The difference is that DBCP will pool connections to the database instead of creating a new connection every time one is requested. We have also set a parameter here called initialSize.

Connection pools are used to enhance the performance of an application and executing commands on a database. A new connection object is created only when there are no connection objects available to reuse.
