Solution for Oracle Error ORA-16623

ORA-16623: database detected role change

What triggered the Error:

A successful switchover or failover operation had been completed and was detected during database startup or broker health check. If this database was unavailable during a switchover or failover operation, it may not be a viable standby database for the new primary database and was disabled by the Data Guard broker.

What should we do to fix it:

Connect to the new primary database and examine the broker configuration for databases that were disabled and that may require reinstatement or re-creation.
