Re: Commons DBCP/Tomcat/Oracle RAC Questions

Fast Connection Fail-over (FCF) is an extension of the Oracle JDBC
Implicit Connection Cache, to RAC. It work in conjunction with RAC
events and Oracle's Notification System (ONS).
In order for Commons db pooling to support RAC similar to FCF, it must
subscribe to RAC events notification and process the events in
questions.

If the Oracle documentation is not enough, you can find more details
(including code fragment) in my book
