If you aren't using a repository all you have to do is make sure control file backups are part of the routine. There are 2 ways to backup the backup metadata: 1) the RMAN repository database; 2) backup controlfiles.
Functionally and operationally they're pretty much the same. The only things you can't do with controlfile RMAN/database metadata is: 1) use previous "incarnations" of the database for recovery; 2) use database stored scripts. No big deal as far as I'm concerned.
When RMAN first came out a separate repository database was a requirement. Subsequent releases added some functionality for using controlfiles. The vulnerability of losing the repository or losing the backup controlfile is about equivalent. The overhead of the repository database is more. With the initial releases of RMAN (EBU) Oracle was rightly criticized for the fact that you had to backup the database that holds information about the database you want to backup. Getting rid of this silliness seems reasonable to me.

And how does one go about restoring a database when all control files
are lost, and the only recovery data is stored in the control file?
This doesn't sound very reasonable.

Joe,
That's what I have heard (from 2 Oracle University
Professors/Lecturers/Demonstrators). But no one would tell me when it may
happen. We do not use RMAN (yet) so I did not pursue it further.

Obilgatory oracle statement/question: rumor has it by some instructors
that RMAN repository is going away and only control file recoveries
will be possible, truth or fiction?
