Connection Pools
A Connection Pool contains named groups 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 pool, uses it, then returns it to the pool by
closing it. Read more about Connection Pools in Programming WebLogic JDBC at
http://e-docs.bea.com/wls/docs61/jdbc/programming.html.
All of the settings you make with the Administration Console are static; that is, all
settings are made before WebLogic Server starts. You can create dynamic Connection
Pools—after the server starts—using the command line (see Appendix B, “WebLogic
Server Command-Line Interface Reference,”) or programatically using the API (see
Creating a Dynamic Connection Pool in Programming WebLogic JDBC).
