no autobackup found while attempting db restore.

I don't know if this is an rman or grid control issue.

I have a database (10.2.0.4) that I'm running backups for via Grid Control (10.2.0.5).  I chose the option to "Schedule Customized Database - Whole Database". 

I ran a full backup and an incremental backup.  I'm including the control file, spfile and archive log options.

I copied all the backup files to a recovery system and began running a recovery process.

I used:

rman TARGET / CATALOG xxxxx/yyyyyy@repository

SET DBID=nnnnnnnnnnnnnnnn;

STARTUP FORCE NOMOUNT;

RESTORE SPFILE FROM AUTOBACKUP;

at this point I get

...
