ORA-16076
        unknown standby database destination
        
        
        Cause
        A standby database destination was specified that was not accessed by another instance. If the initialization parameter LOG_ARCHIVE_CONFIG does not define a DG_CONFIG, then this mismatch may be due to a standby database having been restarted recently.
        Action
        Ensure that at each instance the set of standby databases referred to by LOG_ARCHIVE_DEST_n initialization parameter is the same and defines a DG_CONFIG at each instance to identify those databases explicitly. See the alert log file for more information.
