Charles,
from what I remember, the main restriction always has been the number of
parallel streams you've used to create the backup. If you had two
streams you won't get them back in 3 streams.
When backing up TDP-Ora directly to your tape library, you get the
streams put onto different tapes. Backing up to a diskpool, I'd expect
TSM to use different volumes, too, if possible.
So the question is what happens during migration, space reclamation...

Best wishes,
Michael

Our Oracle DBA's want to do multi stream restores using TDP for Oracle.  I
have read in other posts using TDP for SQl all you have to do is set the
dest stgpool to Collocate by filespace.  Ok, sounds easy but I don't think
that would work for the Oracle DB Backups.  I say this as in the TDPO.opt
you specify  "TDPO_FS            ora_db" so this tells me there is only
one file system for that DB Backup, so collocate by filespace is pointless
if there's only one right?  The only other way I can think of doing this
is each ORA DB would (assuming more than on DB per system) is each Oracle
Instance would have to have its own tdpo.opt with a different tdpo_fs
specified.

Any ideas?
