You need to use Virtual IP and Server side TAF. You need to create Service and make some configuration change so as if the service fail on node1, it will transparently failover to the surviving node providing the same service. No need to change configuration on client side.

You may tweak tns settings on client side for failiover using type=session/select and mode (or method, dont remember the exact technical keyword at this time) to basic/preconnect. Received on Thu Aug 14 2008 - 05:01:18 CDT
