That's mostly correct, just backwards on one point - it's to sync the catalog from the controlfile (the authoritative source), not the other way around. But you are correct that it's just a temp file not needed for restore/recovery operations, so to the OP - no need to change it. In fact, I don't think you can change it to tape. Maybe you're confusing the snapshot controlfile with controlfile autobackup? They are two completely different things and your controlfile autobackup goes to two places:  

  1. On disk to $ORACLE_HOME/dbs (by default) whenver you make a change to your database structure (add datafile, tablespace, logfile, etc.)
  2. To the same channel type as an rman backup, i.e. if you run a database or log backup to sbt_tape and have controlfile autobackup ON, then it will automatically run a controlfile autobackup to sbt_tape after the completion of the database/log backup.
