The primary database runs in MAXIMUM AVAILABILITY protection mode. After loosing connectivity to the physical standby database, the protection level goes to RESYNCHRONIZATION, and remains at RESYNCHRONIZATION even after the connectivity to the standby is reestablished. You wonder when the protection level will go back to MAXIMUM AVAILABILITY.
If you are using the Data Guard Broker and Fast-Start Failover, Fast-Start Failover will not be initiated as long as the Protection Level stays in 'RESYNCHRONIZATION'. The Data Guard Broker will report this Error:
The network connection between the primary and the physical standby database is disconnected for some reason.
