My standby database was running fine.

Before two days it goes down and I have tried to apply pending logs but it gives error.

So I have take another backup of production database using RMAN to create standby database. Restore it at standby site.

But I have getting following error (v$archive_dest at production database)

ORA-16039: RFS request version mismatch.

I have not made any changes at prodction or standby site. I have only restore the backup to create standby database.
