Re: impdp Issue

ORA-12154: TNS:could not resolve the connect identifier specified Means the connection string you’ve used in the DB link does not resolve from the DB server. It will have nothing to do with pdbs/services/sids. Are you sure you made the entry in the right tnsnames file? Have you tnsping'ed from the DB server to confirm it works?

Unfortunately, you’re on 12.1 so you don’t have dbms_tns which helps test things here.

Thanks,
Andy
