Many Thanks Mark.
True. We are setting the Oracle connection string in such a way that all connections goes to Primary Instance. Hence all the connection goes to the Primary database instance.

But recently there was a Primary instance failure and application tried to connect to the other surviving instance. Application got connected to other instance, but we got babdly hit by OR-01861. Later in order to get rid of it we had to bounce the application.

Additinal info :
Weblogic : 8.1 sp5
Clarify CRM : 13.1
