Home -> Community -> Mailing Lists -> Oracle-L -> RE: RMAN - To Catalog or not to catalog, that is the question
Hot backups *were* a great thing before Rman came out. But now, they are no
longer needed. Rman performs the backup with the database is open much
better than the hot backup ever could. And it's greatest strength is at
recovery time. It knows what backup files it needs to apply.
And with the 10G version, it can even produce a report for you telling you which backup files it needs.
A much better solution than hot backups. I would urge anyone to migrate away from hot backups to Rman in a minute. A much more elegant solution.

Dennis,
Thanks. Sorry, I should have elaborated a little bit more...In your post you
said:
>I never got hot backup working, so I can't respond to that issue.
And so, I just wanted to point out that in the process I use my prod db is never shut down and that it is not too hard to get hot backups to work with RMAN on 9.2.0 if you ever would like to try it ;-)
Regards,
Julio

Congratulations. Is there a point here somewhere?

Dennis,
I have three databases on 9.2.0 (prod, train, and recovery catalog) and use OS schedule jobs to run a couple of scripts, which do the following:
Once a week, I copy prod into train using the 'dup' command. And just for giggles...I connect to train Monday morning to check I got a fresh copy of prod and it has been faithful since.
At no point in this process a shut down my prod db.
Kind regards,
Julio

Ron
Joe and Fuad make some excellent points, so I won't repeat those. I never got hot backup working, so I can't respond to that issue. Perhaps someone else on the list can. My gut reaction is that if you have something that works, has been tested, and you trust, then stick with that.
As far as RMAN catalog or not, I would make the following points:

Subject: RMAN - To Catalog or not to catalog, that is the question
We are getting ready to start using RMAN on several new 9i Linux databases. I guess the first question would be is RMAN really that much better then using home grown dynamic hot backup scripts? We have developed these for our Oracle/NT environment and they seem to work fine. The second question would be should we use a recovery catalog? The catalog seems to add a lot of complexity to the setup and to a disaster recovery plan.
Thanks!
Ron
