Answer / asha

In my case when i faced the error, my standby database was disabled.

Just enable the database from DGMGRL and wait for few mins,

DGMGRL> enable database 'xxxxxxxxxxxxxxx';
Enabled.
then you can see

Warning: ORA-16629: database reports a different protection level from the protection mode

will disappear and your primary and standby will sync automatically

Answer / guest

Cause: The actual protection level supported by the standby
database was different from the protection mode set on the
primary. This was likely caused by log transport problems.

Action: Check the database alert logs and Data Guard broker
logs for more details. Check the log transport status. Make
sure at least one standby log transport is supporting the
protection mode and that the network to the standby is working.
