Rman is much better than script hotbackup.Rman backup datablock but os
hotbackup backup datafile.Rman will validate block's head and tail =
during
backup,so it
don't produce extra redo.Rman has many advantages.Setup rman is easy,you =
can
choose catalog or use controlfile store rman metadata.
By the way,why do you choose logical standby?It has many restriction.

=D6=F7=CC=E2: Standy database / RMAN=20
Hi:
=20
I want to implement both 9i Data Guard and RMAN on one of our servers =
(AIX
5.2, Oracle 9.2.0.4 64 bit). This server is in the process of being =
tested.
It will go into production sometime in October. Hot backups are =
currently
being performed nightly (just with scripts no RMAN).=20
1. I want to setup RMAN. How easy or difficult is it to switch from =
these
scripts to using RMAN?
2. I also want to implement logical standby for max availability.=20
-- When the data is refreshed for going live, will it affect =
the
logical standy in any way. I think I will have to recreate it.
-- What about RMAN? How will the backups using either RMAN or =
the
scripts affect the standby?
=20
I am reading the Oracle DataGuard (rel 9.2) on technet and other related
metalink documents.
=20
What else do I need to be aware of? Please point me to anything else you
think I should read before getting started.
=20
Thanks,
