How to resolve Fails-ORA-12545 TNS: Host or Object Does not Exist ???

Check output of following :-
1) If TNS entry is using hostname or Physical IP address? It should use Virtual IP address
2) If local_listener parameter is using hostname or VIP ?? show parameters local_listener --> It should use VIP (not hostname or not physical IP or not virtual hostname should strictly use Virtual IP)
3) If listener configuration is using anything VIP or not???--> It should use VIP (not hostname or not physical IP or not virtual hostname should strictly use Virtual IP)
