Recover full backup into another database

Question

Hello,
I have a particular need that does not seems to be done so often and I just cannot get it.
So here is the situation : I have a backup of a full database. That means that I have the init parameter file, the autobackuped controlfile (+pfile) and the autobackuped backupset.
The source database is release 10.2.0.5.0, RAC instance.
On another server, I have a simple instance, same release and I would like to recover the full backup in the second database.
I have already done that once before but I had both pfile and controlfile backuped manually and the two instances were simple ones.
Here I have tried the same way : shutdown my target database, changing my pfile backup parameters to match the target database. Startup the target database in nomount mode using the pfile. Create spfile from pfile. Then restore controlfile from the backuped controlfile with rman.
But here this step is a problem.
My question is simple : what is the best way / good practices to get this working?
Thanks in advance for your help. Ask if you need any further informations.

And here is the test I have done :
*1. modified the init pfile to this :*

*2. shutdown the database, startup in nomount and restore controlfile (with the error when trying to restore controlfile) :*
