According the the Oracle RMAN class documentation you can't run a 9i
database in a 10g catalog.  I haven't actually tested this to confirm it

"The RMAN catalog schema version (meaning, the version of RMAN that created
or updated the schema) should be equal or later than the catalog database

Subject: RE: RMAN 10G compression

Some questions if anyone has already travelled this ground:

-How much does RMAN compress?
-Can you compress a backup if RMAN is 10G or does the target database
have to be 10G?
-Speed difference w/ compression and w/o compression

We are going to start testing.  However, if someone has already tested
this ground?

Also,  is there a way I can cleanly move over my rman catalog
information for 1 9i database target from a 9i RMAN catalog to a 10G
Rman catalog.
