Fast Connection Failover (FCF) does not work correctly using Implicit Connection Cache (ICC) or Universal Connection Pool (UCP) when connected to a 11.2 RAC database cluster. When a database instance is shut down, all connections associated with that instance are not cleared up from the ICC or UCP. An ONS event is sent from the RAC cluster to the JDBC client when the database instance is shut down, but the connections associated with the shut down instance are not cleared as expected.
