Warning: ORA-16809: multiple warnings detected for the database

Getting the error Warning: ORA-16809: multiple warnings detected for the database when using show configuration in dgmgrl

show database qa3tstp gave me the hit to check if the standby logs are created on primary or not.

Apparently they were not.

In short:

Stopped DR database
Created standby log on primary
Started DR database
