Hi Andy,

Reading the Matthew Hart RMAN book on your behalf I found there now is restore controlfile autobackup from '<autobackup controlfile piece name>'
I still think you are restoring the wrong controlfile. You are using the FRA, and the correct controlfile apparently isn't in the FRA.
You really need to ascertain whether those files are backed-up right after the backup on the source server.
So far you never posted any backup log results, only big pieces on junk pertaining to the restore. Not very helpful. With respect to cataloguing backuppieces, I read the manuals on your behalf and I came up with
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/maint007.htm#BRBSC204

In the past you needed to reproduce the entire source server directory structure on the target server or it wouldn't work. Now you can relocate backup-pieces.
Obviously you can also copy 'missing' backuppieces and catalog them prior to the restore.

Somehow either your backup sucks, or you are restoring the wrong controlfile.

As you seem not to follow my directions to the letter, you are difficult to help, and this is evolving into free consultancy. As I am not looking over your shoulder, and don't seem to be willing to do any background reading yourself, it probably has to stop here.
