Check your CP default MDC settings or set them off all together. The defaults hurt me very bad in a z/VM 3.1 system.

Now after migration to the tserver he complains about performance problems. What I have figured out that he has massive paging only on SQLDS service machine (300-500 pages/s). This I cannot understand, because first he has more memory available as before on multiprise (193 MB vs. 768 MB now) and second we haven't changed the system layout compared to the multiprise. We have migrated the system by dump/restoring the volumes with DDR. So what can cause only the sqlds machine to page so heavily? I have already doubled the virtual memory to 96 MB but this had no effect on the behaviour. Does anybody have an idea, where I can search for the problem? Mit freundlichen Grüßen / best regards Franz Josef Pohlen
