Home -> Community -> Mailing Lists -> Oracle-L -> Re: RMAN - To Catalog or not to catalog, that is the question
just finished my 1.6tb restore this morning and thats when i realised boy rman is good.
rman has a lot of good features inclusding skipping free blocks which makes backups much faster .
I personally believe that setting up a cataslog is good for a couple of reasons.
1. you can get all sorts of reports (management always likes reports).
2. if you have mutiple databases user it.
We actually have our rman catalog on the same server as the tape management server . since in a dr you need to restore a tape management server. yuo will resotr the rman catalog . plus incase you lose the catalgo you can resync fromt eh control files of the database.
Rman has a lot of good block checking features for hotbackups,cold backups and archvielogs which are good.
I've previously before rman had issues with forgetting to add a datafile and then regretting that on a restore.
rman does all that for you.
rman has matured a lot over the years .
it might not be perfect but its still a good solution.

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!
