I am going over ESCON. I have an issue with TSM that I would watch TSM use more and more CPU and actually do less and less. I found that stopping and starting TSM on a weekly basis would get me past it. I have sent them dumps and logs. They said to STOP draining my DISK pool to 0. SO I am trying that. Anyway, my point is, try bringing TSM down and Up and check the throughput then. It may also be worth your time to check and make sure that TSM is in the proper Work Load Manager service class (of course that is only an issue if the machine is running 100%).

What else is going on in your TSM system at the time? Expiration processing slows it down quite a bit. Have you gone through the normal steps of maximizing the throughput on your TSM system?

I haven't found any descriptions for parallelisation, eg. maxpr or mountp. Is it in the tec. nature, the DB will be backed up in sequenz? tia Joachim ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Joachim Paul Schaub Abraxas Informatik AG Beckenhofstrasse 23 CH-8090 Z�rich Schweiz / Switzerland Telefon: +41 (01) 259 34 41 Telefax: +41 (01) 259 42 82 E-Mail: mailto:[EMAIL PROTECTED] Internet: http://www.abraxas.ch ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
