Has anyone on this list ever set up an Oracle UCP connection to an Oracle RAC
and had it supporting all RAC features, i.e. dead connections, failover, etc.?
My question is configuration oriented so I don't think exact hardware/os/tomcat
revs are important.
However, assume Oracle 11gR2 and either thin or OCI client, though I'd prefer
thin, and configuration is via JNDI resource definition.

fastConnectionFailoverEnabled="true"
onsConfiguration="nodes=node1:6151,node2:6151"
with, of course, proper values for the node names and communication ports.
What I'm wanting to find out from someone whose been down this road before, are
there any code changes needed?
