You usually do not use RMAN to create a backup file locally on the
client and then back up that file to TSM.  Instead, via the TDPO api,
RMAN:
1) connects to the TSM server
2) generates a file name
3) checks to see if that file name is currently in use
4) sends a stream of data to the TSM server to be stored in a file using
the generated file name.

I would not want RMAN to store a 200GB backup file locally on the
client.  It would consume too much space and the disk i/o would be a
performance hit. (RMAN is usually used for "hot" backups.)

RMAN should have complete control over how long a backup is retained on
the TSM server.  RMAN maintains a catalogue database to keep track of
which files are required to restore a database.  When RMAN tells TSM to
delete a file, it deletes that file from the catalogue database.  At
that point the file is useless as far as restoring the database goes
because it has been dropped from the catalogue database.  The ability to
restore previous versions of a database is a logical concept RMAN
maintains using the catalogue database.  So once RMAN tells TSM to
delete a file, there is no need to hang on to it.

another tought question ... :-)

why are recommended values for mgmt class 1-0-0-0 and not 0-0-0-0 since
RMAN should do deletions of backups ?

thanks in advance.
