tnsnames.ora file for a Oracle 11g database in vcs cluster

Hi All,

I have a database which is a part of vcs cluster. I need to have a tnsnames entry such that the client can connect to wich ever server is up in the cluster.

eg, server1 ( and server2 ( are in a vcs cluster (
and server1 is active. Now, when there is a server1 failure then it should automatically failover to server2.

How do I setup my listener.ora file and tnsnames.ora file so as to be able to failover automatically?

i have never worked with VCS clustering before, so any input is greatly appreciated.

Sofar as i recall it is possible to double some values in tnsnames.ora file, like IP addresses
there is something called a VIP “Virtual” IP address which will always point to whatever active in your cluster ;
ask your sys/network admin about it
