ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
I have a switchover problem.Please help to see what's wrong on my setting.
Two nodes cluster database on 11.2.0.3 as primary.
db_name: prd1108
db_unique_name: prd1108
instances: prd11081,prd11082
service_names: prd1108One node cluster database on 11.2.0.3 as physical standby.
db_name: prd1108
db_unique_name: p1108sb1
instance_name: p1108sb1
service_names: p1108sb1
I have checked that all network settitng are correct. Each node can tnsping all above services.
From original primary node, I can use dgmgrl to do switchover.
But when I try to switchover from the new primary (p1108sb1) back to new standby (prd1108), it cannot complete. I have checked and see the listener is working fine.
