Oracle 12c RAC- single instance

The alerts are as follows:

DGMGRL > show database verbose coredb;Database-coredb Role: PRIMARY Intended State: TRANSPORT-ON Instance (s): coredb1 coredb2 Database Warning (s): ORA-16629: database reports a different protection level from the protection mode. Omit.

The protection mode is set by us and the protection level is in the current state.

SQL > select database_role,protection_mode,protection_level from vested database share database-- PHYSICAL STANDBY MAXIMUM AVAILABILITY * * RESYNCHRONIZATION**

Because of the test, the log transfer process defer is dropped, and hundreds of archives need to be chased after re-enable, and the highest available file is degraded to maximum performance mode, which becomes asynchronous. I have done a test in the test environment and found that there will be no alarm after I find it even. The above is only one record.

After leveling:

SQL > select database_role,protection_mode,protection_level from vested database: Database role PROTECTION_MODE PROTECTION_LEVEL- PHYSICAL STANDBY MAXIMUM AVAILABILITY MAXIMUM AVAILABILITYDGMGRL > show configuration Configuration-dg_config Protection Mode: MaxAvailability Members: orcl-Primary database orcldg-Physical standby database Fast-Start Failover: DISABLEDConfiguration Status:SUCCESS (status updated 13 seconds ago)

You don't have to do anything, just sit back and wait for everything to get back to normal! We just need to know why!
