JDBC Connection Pools

A JDBC connection pool is a named group of JDBC connections to a database. These connections are created when the first request for connection is made on the pool when you start Sun Java System Web Server.

The JDBC connection pool defines the properties used to create a connection pool. Each connection pool uses a JDBC driver to establish a connection to a physical database at server start-up.

A JDBC-based application or resource draws a connection from the pool, uses it, and when no longer needed, returns it to the connection pool by closing the connection. If two or more JDBC resources point to the same pool definition, they will be using the same pool of connections at run time.
