Hello All - i am using netbackup 773 on Redhat Linux 5.X master and media server .
I have requirement , in my oracle environment if i have only control file without catalog file will i be able to backup only control file without catalog.
Solved! Go to Solution.
I see the following lines from the NBU77X Guide for oracle :
An RMAN recovery catalog or the database control file is a repository for the information that RMAN uses and maintains. RMAN uses this information to determine how to run requested backup and restore actions.
And also i see the following line:
Oracle recommends that you use RMAN with a recovery catalog, especially if you have 20 or more data files. However, you are not required to maintain a recovery catalog with RMAN.
In this case even if the RMAN doesnot have the recovery catalog would i be able to backup with the help of control file or is it mandatory to have catalog.
@SmallingThink there is some confusing here, a RMAN catalog is another Oracle database or a part of another Oracle Database not a file. Even with a RMAN catalog, the control file usually still holds some information about backups of the database.
Using a RMAN catalog gives some extra possibilities as far as I remember. Your DBA can probably give you an up to date information about what they are exactly now.
