ORA-16629: database reports a different protection level from the protection mode
Cause: The actual or current database protection level was different from the configured protection mode. This typically is caused by redo transport problems.
Action: Check the database alert logs and Data Guard broker logs for more details. Also, check the redo transport status. Ensure that one standby database supports the configured protection mode and that the network to that standby database is working properly.
