A JDBC connection pool contains a group of JDBC connections that are created when the connection pool is registered, usually when starting up WebLogic Server. Your application borrows a connection from the connection pool, uses it, then returns it to the connection pool by closing it.
After creating a JDBC connection pool, you can create a data source or tx data source that applications can use to access the JDBC connection pool.
To create a JDBC connection pool, click the Configure a new JDBC Connection Pool link.
