Michael,
You might look at the BLKSIZE parameter. I did some basic tests using NT
and the EDM client, and found that setting the BLKSIZE to 2 Meg was the
fastest for my installation. I think the default is 64k.
You set the parameter like:
allocate channel d2 type 'SBT_TAPE' parms 'BLKSIZE=2097152';
Hope this helps.

Hi All,
I use RMAN to do a full backup of 120G database while the database is up
running. It takes around 6 hours to finish. I have 61 data files and
manually allocate 6 channels. For all the RMAN parameters such as
FILESPERSET, I take the default.
Does anybody there know how to maximize the throughput?
Thanks,
Michael
