I have a doubt.

Is it possible to make RMAN to use controlfile, from using Recovery
Catalog(RC) DB ?

The scenario is like this:
I have a target db and a RC db. The RMAN presently uses RC db for
backup and recovery.

Due to some reasons, I want the RMAN to use target db controlfile,
instead of RC.
Is there anyway to perform this?
If yes, I need the RMAN to understand and use backup sets, which are
taken before switching to controlfile based backup (That is,
controlfile should understand backup sets, which have backed-up using
RC )

Is there a way to perform these tasks?

If I were you I would go to forums.oracle.com and ask there. The
groups there are active and spam-free.

As far as I can see, usenet (now transformed into groups.google.com)
is dead - there are now better alternatives.

You should ask that question on oracle-l. They welcome questions like

Rubbish. This is the only forum that is not moderated, which makes it
invaluable. Usenet is far from being dead. CDOS is visited by sufficient
number of old hacks to be interesting and it doesn't generate megabytes
of traffic per day.
Also, it doesn't have much to do with Google. You can access it through
Google, but you don't have to. I don't use Google to access my Usenet
groups.

I haven't done this myself, since I don't use a catalog, but I see
there is an unregister command. You'll want to understand the delete
and crosscheck commands, which do change over some versions.

There may be some other considerations, so you might want to say why
you are doing this. There are also version dependencies, so it is
always a good idea to state exact versions and platforms.

cdos is not dead yet. Even though I haven't updated the readme for
cdos in a while, I do have a list of updates I haven't got to yet.
Hmmmm, what happened to my site? First problem I've had with that

Usenet is not dead, it still exists as it always did, for access by
people using real newsreader software. Google groups is just an archive
(still useful) and an interface to current activity which is quite some
way off being good enough.

As for "better alternatives", they all depend on some person or company
continuing to maintain the relevant website, something for which there
is no guarantee whatsoever. Usenet is not dependent on any single person
or company, and there is enough interest to ensure that it will be
around for a long time yet, And there are ways of dealing with thw spam.

So please stop talking rubbish and let people realise that they will get
answers here, though they will also be pushed into thinking for
themselves. Anyone who wants to call themselves a DBA needs to be doing
a fair bit of that!

RMAN>

There are many ramifications, especially with device type SBT which I
don't have on my home computer, archivelog records, compressed backup
sets, incremental backups etc. This is a basic example how to backup
database.

Then you can check what backups you have:
RMAN> list backup of database;

You can also see whether the backup is good:

RMAN> validate backupset 2;

Starting validate at 28-SEP-11

You can also remove backups:

RMAN> delete backup of database;

using channel ORA_DISK_1

This is a brief example. For everything else, you should use the
available literature.
