Walter - As RMAN was introduced in Oracle8i, that was the ideal. I think
Oracle viewed RMAN as a high-level feature that would help you manage the
backups for large server farms. They emphasized that the catalog was the way
to go. With the catalog on another box, if the server was toasted, you could
slide another system into that spot and with a couple of RMAN commands you
could have that up and going again. Obviously if you use the catalog method
on the box you are backing up, you must have a second instance, and even
then you introduce more vulnerabilities than the configuration where the
catalog is on another server.
With Oracle9i, Oracle added many of the features that were only
available in the catalog method to the control-file method. According to my
Oracle Education Instructor John Hibbard who is pretty plugged into these
things, Oracle is trying to emphasize that the catalog method may not suit
everyone's situation and the control file method may best suit your needs.
As others on this list have pointed out, not all conference speakers have
gotten that message.

Hi,
Can anyone think of a reason(s) why one WOULD want to backup a database from
a box other than the database box itself? Are there any advantages to this
kind of configuration?
For example:
Box-A (production db server)
Box-B (rman db server)
A cron job runs on Box-B which backups up the database from Box-A.
Thanks in advance!
