Oracle Error Message
ORA-16629: database reports a different protection level from the protection mode
Reason for the Error
The current database protection level was different from the configured protection mode. This typically was caused by redo transport problems, or the primary database was not open.
Solution
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. Ensure the primary database is open.
