Nodes # : 4
Operating system : Redhat 6.6
When trying to configure enterprise manager the following error appeared :-
Connection to the database cannot be established because the listener could be down. Please make sure that the service is registered with a listener and the listener is up.
The listener is up, VIP is working on all nodes without any issue when check dbca logs looking for more details i found this error :-
dbca trace in $ORACLE_BASE/cfgtoollogs/dbca.
ORA-1017: invalid username/password
Both was correct, because of this i recreate password file on all nodes and restart my operation it’s working without any issue this time.
