I'd suggest you to investigate the real problem with Oracle Support instead=
 of downgrading the version

Subject: Downgrading Oracle RMAN catalog from 11.2 to 10.2

I just upgraded an RMAN catalog yesterday from 10.2 to 11.2 and the backups=
 were 20% slower overnight, so am suspecting the catalog version for now.  =
I updated the stats as well, but doesn't provide me with a good estimate. I=
 can do a restore of the database before the upgrade, but just wanted to se=
e if I could do it without a restore.

Anybody have any experience having to downgrade a newer version RMAN catalo=
g to a lower version (ex. from 11.2 to 10.2, etc).  Any ideas, how to do th=
at?
