BTW I've always thought the IXCLOnnn group name to be particularly
USELESS and unmnemonic. Likewise the member names - Mnnn. Imagine the
(frequently-observed) case where there are several lock structures - GRS
Star, several DB2 Data Sharing Group LOCK1 structures etc. How to tell
them apart

Not that I disagree the naming convention is not intuitive, but can you
suggest a better convention to the XES developers? When you

that group?
A good question, Barbara. You're actually making me have

Lizette,

Try checking whether the system you noticed the CPU spike on is the CNS
using a D GRS

Is this the case of getting a XES contention response back from XES? (I

I have been noticing lately that when I am in the SDSF DA screen sorted by CPU%

RESMIL will affect CPU utilization. In my RESMIL=OFF experiments I've
noted increased processor usage. My system is lightly loaded though,
and I've not seen utilization as high as yours.

One master cat and one sysres set.
We are STAR with 5 LPARS (2 Prod/2 Devl/1 Sysprog)
2 Physical boxes, and one ICF on each box.
One is a z9 (3 engines) and the other a z890 (3 engines).
z9 has 3 LPARs, 1 Prod, 1 Devl,

What sort of system config do you have (GRS
We had this in the past because of several thousend ENQ for DB2 tablesspace.
We exclude these in the GRSRNL. This is dangerous and can be a pain. So
make sure you do NOT share these data. Search the archive for more info.
AFAIR we save 50% of the GRS CPU
GRS provides a nice as-is monitor. I

Is this something I need to look at? It is not very long, maybe a couple of
seconds up and then down again?
If so, what
