Database Software

How does RMAN know where on your system the .bus files are that are to be restored? I understand that it has to be based on what's in the controlfile, but is what's held in the controlfile based on where RMAN on the source server puts the backup?

What spawned the question is a situation where I'm going to have to restore our prod database to our dev database, and in the case of the prod server the backups are in /ocfs2/oracleBackups/tmp/ . During my test restore to another separate server, there was enough space on the root to extract the backup and run the restore. I'm assuming RMAN found it because it was in the same exact path as was on the source server. Now to complicate things, the destination server doesn't have enough room on the root to extract the backup, so the path to the datafiles won't be the same.

Is this going to cause a problem, and is there a workaround?

Any help is greatly appreciated.
