ther are no other activ processes, no waits for mountpoints, the db looks o.k., the throughput maybe is limited by ESCON.

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 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
