Title: RE: RMAN question (figured out if anywone is interested)with another question appended. :)
Apparently the command:
backup database format '/oracle_backup/ASTU/%U'
(current controlfile);
..places the controlfile in $ORACLE_HOME/dbs, but:

Chris - Congratulations on finding your problem. I have the RMAN log file
emailed to me for each backup. This means more to look through. What you

Dennis,
I wasn't actually restoring the control file. Only 'validating' that RMAN could do it. I also backup the control file several other ways and would likely never ask RMAN to perform that function. The only reason I issued 'restore controlfile validate
Chris - Thanks. Sorry for the tirade, bad day, reading too fast, thinking
too slow. I checked my systems and I see the snapcf_SID.f files, one for
each database being backed up. I do not see the other files you mention. I
notice the mystery file names have a format quite close to your backup
Chris - Do you have any more details on the files you deleted that you felt
were snapshot control files? How large?
I may be incredibly stupid, but for the life of me I can't figure out why
you would ask RMAN to restore your controlfile from backup. Was it corrupt?
I would assume bad things
Helmut,
This thread came up a couple of days ago
The answers were to use the commands

No, you can't do that. I just run a OS job everyday which removes the old
backups to make room.

I have the same situation.
I my case I used 2 channels, and
so around a 25-30% decrease in

Once I increased it to 3
channels
the payback was minimal. It also
became very cpu intensive,
so I kept the setting at 2.

Rman channels are like processes, and you can have multiple channels writing
to one disk and reading from one disk in a restore, If your server has the
horsepower, then multiple channels will increase the speed of backups and
restores,

Joe,
We only write out to tapes, so one channel
equals one tape drive, each extra channel goes and gets another drive. Not too
sure about disks, I guess it depends on I/O bandwith. Two channels will be
faster than one, if the disk can cope with the input from two channels then
maybe it

1) Why do you feel writing RMAN backup to one disk is not ideal? Is it
the one disk, or disk vs. tape?

Can autobackup of control file be NOT enabled?
If you do full database backup using RMAN you get the controlfile like it

I don't have a clue about RMAN and you say it is a trick question.
I think control files from time a and time b are the same and should work.

Oracle 8 used the catrman.sql script to create the recovery catalog schema,
but in 8i you use the RMAN command:
create catalog
I'm not sure because I never used RMAN with Oracle 8, perhaps someone more
knowledgeable
Dennis is correct. If you are on 8i you won't need the catrman.sql script.

If I understand you correctly, you are using RMAN to backup to disk,
rather than to a media manager. You are asking whether you can archive these
in RMAN, plus leave them on disk so they are readily available for recovery.

You must use RMAN for restore as the format of the backup pieces can be
understood only by RMAN. Since RMAN is an Oracle - internal process, it
reads the database a *DB* block (or multiples thereof) at a time, rather
than the OS read an *OS* block at at time which could result in

Hi,
Your
initial statement is correct. If you use rman to backup, you must use it to

You should backup all of the archivelogs if you are going to delete them and
maybe even if you are not. The redo logs contain data which is already in
the database when the backup is made so you don't need to back them up.
In my scripts I always to an 'archive log current' and backup all of

online production instance and reporting instance. We refresh reporting

I forgot about the second part. The answer is yes but I have never done it
successfully. Check the documentation.

Cold bacpup should backup online redo files. Level 0 did'nt include
online redo files. If I do alter system archivelog current, should I
backup archive files as well? We are in archive mode.

Joan,
RMAN does not backup online redo files. If you take a cold backup, then restore it,
you need to issue an 'open database resetlogs'. These documents on MetaLink may be
