I'm not positive, but I don't think there is any way to do it other than
editing the table directly (which is most likely not supported by Oracle). I
don't think RMAN actually uses that media value for anything though - it's just
there for reference. It also won't tell you if a backup spans more than one
tape at the time of the original backup, and won't give you anything very
meaningful at all if you're backing up to a Netbackup disk pool instead of
straight to tape. When RMAN queries Netbackup for the image during a
restore/duplicate/crosscheck, it just queries based on the client name, policy,
image/file name and maybe date/time (not positive on the exact pieces of
information it uses to look up the backup image - but it's something close to
that) and then Netbackup looks it up in its internal catalog and pulls the
requested backup image from whatever media it currently resides on.

Brandon
