Michael,
What version or Rman are you looking at? I really did not appreciate Rman
before 8.1.7 and it's predecessor in version 7. Rman for Oracle 9i is damn
nice. Instead of those messy scripts and a recovery catalog you now have the
ability to store all that stuff in the control file. Then a simple
rman << EOF
backup database
EOF
is all that is needed in 9i. Yes the syntax is a little more messy if you lose
your control file for recovery purposes, but at least rman can now rummage
through that backup and retrieve the control file. We make limited use of rman
here right now, but will we ever increase that in the future.

Michael,
I use it. I trust it. Oracle support is there when needed.
When you say "While I can get RMAN to work for most simple, basic and
predictable recovery scenarios, true
recovery situations are never so neat and clean."
Just what do you mean? Loss of individual tablespaces? What?
To be fair, I would suggest that you create a test database, and use Rman to
perform backup and recovery operations on it. Try and beat the product so
it doesn't work for you. You'll be surprised.
Once you see how it works, I think you'll realize that it has matured into a
good product.
Hope this helps.

As a longtime Oracle DBA who has used many products, including RMAN, I find
myself
guilty of a paradoxical mistrust of RMAN, dating back from the time when
Oracle has tried
several products, including integration with Legato and other
hardware/software backup vendors,
without a consistent direction. In the little I've used RMAN, it seems
quite complex and kludgy.
Even the nomenclature and commands used by Oracle within the product are a
challenge to learn.
While I can get RMAN to work for most simple, basic and predictable recovery
scenarios, true
recovery situations are never so neat and clean. This is not an
advertisement for any particular
product, but we've had great success in my shop with a product called
SQL*Backtrack from BMC.
I've also heard that Veritas makes a good product, but I've not used it.
>From what I've seen of RMAN, at least so far, I feel far more confident with
the home-cooked scripts
I've been using for years.
Any comments, or other interesting experiences?
Perhaps we can do a list poll of favorite/preferred backup software?
