Start of Service Fails with ORA-16000 on Physical Standby Open for Read Only

Start of database service failed with ora-16000 on physical standby where both CDB and PDB are open read only mode. The DG setup is same one mentioned in earlier post Data Guard on 12.2 CDB.

Reason seems to be creating the service with physical standby role is trying to add some rows to the read only database. To fix problem first add the service to the primary with role as physical standby and start the service. It may seems odd to start a database service that it is defined for a physical standby role but that's what needed to resolve this. Once the service is started stop it on the primary before the next steps.

Do few log switches and wait until these logs are applied on the standby. Once logs are applied on standby create and start the service on standby.
