Also make sure that in the NetBackup Configuration for the Master that
Maximum Jobs per client is set to higher than 1, I like 99 because it has a
nice ring to it.

Then try setting Multiplexing to 1 and re-run the rman job.

If you want to use Multiple streams from a standard job, set the file list
to ALL_LOCAL_DRIVES and play with the bpstart and end notify scripts to
manage the number of streams you will create.

Ted,

You are mixing up multiplexing with multistreaming..

multiplexing is taking several different clients and having them back up
to a single tape drive..

multistreaming is what you want where a single client can backup to
multiple tape drives..
