A Connection Pool is maintained internally by the Connection Pool Manager. When a request for a subsequent connection comes in, the Connection Pool Manager searches the pool for the availability of a free connection and returns it to the application if one is available.
1.If any unused connection is available, it returns one. 2.If all connections are used up, a new connection is created and added to the pool. 3.If the number of connections reaches the maximum number of connections in the pool.
Connection pooling is enabled by default.
