Warning messages after failoverI failovered to standby database. The following message kept on loged in alert log.
RFS: Assigned to RFS process 18298 RFS: Database mount ID mismatch [0x5f0edd7b:0x5788f47c] (1594809723:1468593276) RFS: Destination database ID mismatch [0x5bb6deb1:0x5775211a] (1538711217:1467293978) RFS: Not using real application clusters
I unset fal_client, fal_server, and log_archive_config the message wont go away.
Suddenly realized that the old primary is still sending archive log to this new standby.
SQL>alter system reset log_archive_dest_2; (this is a 10g db) ERROR at line 1:ORA-00905: missing keyword SQL>alter system set log_archive_dest_state_2=defer; System altered.
That stopped the message.
