9i Offers automated recovery of the control file. All you need to know is
where you are making your
control file backups to (tape or disk), and the DBID of the database you
wish to recover the control
file of. If you forget the DBID, not to worry because it's stored in the
file name of the backup
pieces that contain the control file so you can play around and find the
DBID that way.
9i RMAN is much easier in this respect than earlier RMAN versions.
Still, even if you loose your control file in 8i, it's not too hard to
recover that control file
as long as you know where your backup pieces are. You just need to mount the
instance and use
dbms_backup_restore to recover the control file from the backup set. It's
perhaps not the most
straight forward method of doing this, but it works.
Shameless plug - This is all documented in Oracle9i RMAN Backup and Recovery
by Oracle Press. :-)

Igor - Hopefully you won't lose your repository at the same time you lose
all your production database controlfiles. However, if that is happens,
hopefully you were outside the computer room at that moment. ;-)
So, you should be able to recover your repository and/or take a fresh
backup.
I should point out that even if you use an RMAN repository, the recovery
information is still stored in the control files, so you can still perform a
control file recovery. But Jared is correct that it is much more difficult
if you must try to recover the control file from the RMAN backup piece. That
is why I separately back up the control file (binary backup) after the RMAN
backup. I understand this is all much better in 9i.

Doesn't the same apply to database repository, when it's lost?
