Make sure "allow multiple streams" is set for the class(es).  With the
standard version of the backup, use the NEW_STREAM option in the filelist

Ex:     NEW_STREAM
        /var
        /home
        NEW_STREAM
        /opt
        /work01

With the above example, two streams will be launched, one stream backing up
/var & /home, the other /opt & /work01.

                Subject:        [Veritas-bu] Backup using more than one tape
drive.

                Hi All, my question is in two parts ...

                1) I am trying to backup a 500+ gig ORACLE database to my
StorageTek L700
                tape library using more than one tape drive!  The library
has 6 fibre 9840
                tape drives.  I have run a backup once but it only utilized
one tape drive
                and it took 26 hours!  I am wondering if there is a way to
make it use all 6
                drives in the library for the backup.  The machine that will
be backing up
                the database is a media server (not the master) and is
connected directly to
                the fibre network.  I am using NetBackup to run the backup
(Standard Class)
                not RMAN.  Both the Job and NetBackup have a maximum
multiplex of 8.

                2) Our Oracle Admin was trying to use RMAN to push a "HOT"
Backup of the
                same database and told rman to utilize 5 of the six tape
drives, but it was
                only using 1 for some reason!  Should I have the Media
Multiplexing set to 1
                on the ORACLE Class backup?  Any help with this would be
appreciated!

                Thanks

                Ted Carr
