But you will need to catalog the backupfiles to the primary db control file. In my example, use this rman> catalog start with '/opt/oracle/rman/std1'; 2)The standby crontolfile is a standby controlfile on the point view of primary. That's why rman says it is not a current controlfile. A current cotrolfile is always the primary db controlfile. After you active the standby db, its controlfile is current. You do not need to stop the standby db to do recover. If you have questions, I'd like to help. Regards, Alex Hi Susan,
1)Yes, it’s ok without catalog. But you will need to catalog the backupfiles to the primary db control file.
In my example, use this
rman> catalog start with ‘/opt/oracle/rman/std1′;
2)The standby crontolfile is a standby controlfile on the point view of primary. That’s why rman says it is not a current controlfile. A current cotrolfile is always the primary db controlfile. After you active the standby db, its controlfile is current.
You do not need to stop the standby db to do recover. If you have questions, I’d like to help.

I do have two questions: 1) is it possible to do this if you are not using a recovery catalog? If so, how would the steps differ? 2) why in step 7 isn't the control file on the standby current. I would think that if you are using the standby to recover the primary that this would be the current control file. Most likely, your primary has probably been down for a while and datafiles could have been added to your standby. At least this is the situation I am in and I am trying to figure out how to restore the primary from the standby without shutting down the standby. Any advice would be greatly appreciated. great article – this is the first article I have seen on how to use the standby database to recover the primary. thank you!
