The control file is going to be an issue.
Even if you have CONTROLFILE AUTOBAKUP set to OFF, any backup including system tablespace should include a current control file backup.
Find it and use this :
Autobackup is not available but controlfile backupset is available
RMAN>RESTORE CONTROLFILE FROM '/backup_dir/piece_name';
If you can find the control file this may help :
rman target / startup nomount; restore controlfile from <backupset_location>; alter database mount; restore database; --required if datafile(s) have been added after the backup recover database; alter database open resetlogs;
RMAN recovery to a different server when nocatalog is available
Refer this You can take a look at this http://shivanandarao.wordpress.com/2012/04/19/duplicating-primary-database-to-a-new-host-without-connecting-to-the-primary-database-in-oracle-10g11g/
RMAN automatically backs up spfile and controlfile in the backup of datafile 1 (SYSTEM datafile). So, you can restore them from the backup piece that is having the system datafile.
