Hi, I am new to RMAN, so maybe its a dumb question. Oracle documentation states that RMAN repository data is always stored in the control file of the target database. And that the repository can ALSO be kept in the recovery catalog. So it can be in both places or just one? If I choose to keep it in the recovery catalog, then I dont have to have it in the control file of the target database?

thank you!

The controlfile is normally limited as to how much (ie. how many days) RMAN data it can contain. The recovery catalog is essentially unlimited. The same info is kept in the controlfile and recovery catalog for a duration. It will eventually be aged out of the controlfile.

Check RMAN Repository.

So I don't have to keep it in the control file then? I just got confused by the word "ALWAYS HAVE TO KEEP". thank you!

It will kept it in the control file by default, recovery catalog or not. No way around that. However, the amount of info in the control file is governed in part by CONTROL_FILE_RECORD_KEEP_TIME.

That being said, there are additional components that the recovery catalog can maintain (ie. backup/restore scripts) that the control file can not maintain.

Oh, ok, so it will be kept in the control file no matter what. However, if I create a recovery catalog it will ALSO keep it there?
