Ok... I purged and redefined the DCSS, and now I don¹t get the message; I¹m
waiting to see if it really starts collecting.
I did ³DEFSEG 9000-AFFF SC RSTD², matching our previous segment.
My questions now are, What happened to the prior segment that caused it to
fail? Could the problem have been
Robert,
HCPMOV6274I The sample data messages and corresponding records have
been purged.
Just a thought - did you log off of PERFSVM and back on? I'm wondering if
that virtual machine is pointing at the previous address of MONDCSS.

Re: Perfkit SAMPLE CONFIG size too smallThis is usually caused by zVM accessing
lots of additional I/O devices that it previously didn't see. While redefining

There is no single 'right' MONDCSS size for all systems: it's about
performance,
so 'it depends'. The MONDCSS has to be large enough to allow the CP monitor
to place all the monitor records you told it to collect in that storage
area. Since
most users just go and enable whole domains, it's the
I plan to talk to the hardware people in a moment to see if anything was
added recently?
We do have a large amount of DASD that is really owned by z/OS, which we
immediately take offline, but they¹d still be in the config area.

Not sure if my previous note on this was distributed. There is NO
problem with having an oversized MONDCSS. A small one however stops you
from collecting data. Our default is now 64mb.
