Oracle Parallel Server - Configuration/S

I have an issue here. I have OPS installed. I have areound 2 -3 clients connecting to the Oracle Server. I also have configured the Server to have Failover feature. I have manually configured the tnsnames and listener (though i have enabled for theSecondary Listener to listen). But when I check the v$session in the respective columns i find that both of them have NONE in them, for an application. I am able to have this featuer ON for Oracle SQL Client. What could have been the problem
