Linux RHEL4/Oracle 10.2
I'm testing out recovery scenarios. I successfully executed the below command in rman:

run {
allocate channel dev1 type disk;
backup incremental level 0
format '/d20/oradata/T_DEV/backup/t_dev_backup_%U'
database
include current controlfile;
release channel dev1;
}

When I attempt to restore my backup to the new host, how can I restore the controlfile I backed up in my command above? Do I need controlfile autobackup enabled?

Thanks.

If you enable that then only this command

RMAN>restore spfile from autobackup.
RMAN>restore conrtrolfile from autobackup;

The only syntax I can find is:
restore controlfile from autobackup

What if I do not have controlfile autobackup enabled? But rather included the:
'include current controlfile;'
within my rman script as detailed in my initial message?

you can also use

RMAN> RESTORE CONTROLFILE from 'filename';

RESTORE CONTROLFILE FROM TAG 'monday_cf_backup';

You didn't read the page.
I didn't say I posted the full syntax, it is the way to use it.
You have to work a little bit.

Copy the backupset into the new host. And in new host use file location and use .

As you are using OS command to copy backup set into a new host so RMAN does not know where the backup set is. So you manually specily filename clause to locate your backupset.

restore controlfile from 'filename' ;

not neceassry because backup information is in controlfile the oracle will read the controlfile
for backup only one thing matters
and that is the location if you gonna paste
the backup to same location then just enter the command

restore database;

Thanks so much. I was going back and forth with error messages, but your simple, straight-forward explanation did the trick!

Except that in this case, the control file itself is what is being recovered .... Shocked

Michael,

Oops! I got sucked in by the 7-year (almost to the day!) "thank you" and failed to notice the dates of the OP. Embarassed
