ORA-16816: incorrect database role
Cause: The Data Guard broker detected that the specified database had a database role that was different from the database role recorded in the Data Guard configuration. This could be the result of a failed switchover or failover operation, or an out-of-band switchover or failover operation done to the database.
Action: Manually fix the database to convert it to the appropriate database role, then issue an ENABLE DATABASE command to reenable the database.
Error Type: ORA
