What entries should exist in oratab for 19c RAC?
This is multi-tenant environment on RAC 19c.
The 19c RAC guide it says the db_unique_name should be in oratab that EM will use this.
About ORATAB Configuration for Oracle RAC
However if I try to use oraenv it requires the instance names be there. I seem to recall that expdp required the instance be defined in oratab in earlier versions.
Do I need both SID and Uniq for the containers?
I think the upgrade from 12c to 19c required adding pdb names to oratab.
Do I need pdbs defined in the oratab if not upgrading?
I also see service names defined in oratab which I don't understand why that is needed - that should all be in TNS I thought.
