The assumption is being made that only for the catalog is recovery for production failures.

There is a fair amount of reporting and analysis that can be done from the repo that cannot be done from the controlfile.

  • data that is not retained in the controlfile
  • retention of data in the repo can be longer.

Another useful thing for repos:

If your company archives data of site via NetBackup vaulting, or something similar,
good luck restoring a quarterly backup from last year without a catalog.

It can be done, but it is much simpler if the metadata is retained in the RMAN catalog.
