Paul:
BRMS will have some small effect on the performance (it has to read its
databases) but not what you're reporting. I suspect the restore is causing
the disk I/O to spike and since restores are one thing that run in the
machine pool, paging/faulting there. I suspect you've got the machine pool
set up to be fairly small since ordinarily it does not use that much memory.
I suggest you bump that up considerably if possible during a restore. I/O
is what it will be. If you are driving lots of I/O then it's going to show
up.
Is this a hosted environment or real disk?

Subject: BRMS RSTLIBBRM jobs impacting RDI and LPAR performance
Occasionally, we have to run some BRMS restore jobs (RSTLIBBRM) during prime
shift, 8-5.
The BRMS restore jobs are having a large impact on RDI performance, and
other LPAR jobs.
From MPG perf graphs, disk response time, machine pool faults have large
increases.
Has anyone from the group have/seen this same behavior.
What, if anything, can be done to minimize/eliminate this impact.
Also, what system jobs are used for the RDI communications?
Thank You
