The "it depends" answer is right on... I've seen
places that had inadiquate resources to run a database
let alone RMAN at the same time. Then there are places
that have much more hardware than they need (oh, if
only every client was this way). Bottom line is it is
very possible for RMAN to run and not have anyone
notice. You can also throttle back RMAN operations
(this is much easier in 10g) so they have less of an
impact on overall performance.

Check out our new 10g RMAN book! It will be out soon!
