Re: what if recovery catalog is lost?
Ruth, Do you know if it's possible to make backup of recovery catalog using export/import? Regards, Alexandre - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Tuesday, May 28, 2002 6:08 PM I have put my recovery catalog database in archivelog mode. I do a cold backup of the database and the archivelogs each Friday. This way I won't lose it. Ruth - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Tuesday, May 28, 2002 4:58 AM Hi, That strange, but this has never come to my mind before. Ideally, the recovery catalog should be on other than production server (and it always was for me). And recovery catalog's database should be copied as well. Perhaps, using production database for recovery catalog. What if recovery catalog and production database crash at the same time and there is no way to recovery database with recovery catalog? I need the functionality of RMAN with recovery catalog, but I don't have separate server :( so I'm going to place it on the same server, but different database. I'm going to backup both databases symbiothically using each other as recovery catalog. If something goes wrong and server crashes with both databases, I will have backup copies but no catalog.

I'm not sure about third scenario - recovery target database without recovery catalog with backups taken while recovere catalog existed. I'm going to test this cases before set it up in production and I'd like to know about you experience in that area. Thanks in advance.

Re: what if recovery catalog is lost?
Yes, it is very possible. That would work as well as a cold backup. I just wanted the archivelogs too.

RE: what if recovery catalog is lost?
Alexandre - Often RMAN is used only once or twice a day, so it easy to export it. The other advantage of the export is in case of a disaster recovery onto a loaner machine, it is easier to get your RMAN catalog back running. You can copy the export over to the target system so that gets written to the backup tape, along with the backups, so for disaster recovery you only need a single tape.
