we have a Oracle 9i db as rman catalog.
We have several Oracle version DBs (8i,9i and10g). I want to backup them using the same rman catalog.
I create rman catalog using 10g scripts.

I'm getting error when i try to connect to the catalog using as a target the oracle 8i database.

>rman catalog rman/rmanora27@alias_cat target sys/sys@alias_8i
