We are seeing an increase in DB2 DDF processing. At the same time we
are seeing an increase in CPU utilization for the OMVS workload. Are
they related? Does DB2 DDF processing utilized Unix Systems Services
and OMVS? We are at DB2 v7.

Hi Tom,
If this is enough for you to notice have you looked at weather you could
offload enough time on a zIIP engine to justify one or more? You can
specify in IEAOPTxx to measure the zIIP eligible time even without
having a zIIP and get a pretty good idea what you can offload if you
have the co

Leon,
The value is at offset 128 in the Processor Accounting Section of the
SMF type 30 record. It is variable CPUZIETM in the JOBS and STEPS
datasets of Barry Merrill's MXG system if you build a performance
database with that software.
I've found out that I have another problem trying to get th
I do not have the specifics, but I know while running DB2 V7 we were able to
run SMF data through a 'special' program, I sent the output to someone else
in our company, and they did the zIIP analysis. Not knowing the source of
the 'special' program I am not going to pass it around. Not wanting t
This is not correct. zIIP sizing analysis can be done using DB2 Version 7.
See
the below description of how IBM can perform zIIP analysis using tools and the
data needed as input.

The difference between what you get with DB2 V7 and SMF 101 vs DB2 V8 and
PROJECTCPU might be interesting...
I believe the former would be from measuring the appropriate CPU for DDF
and ESTIMATING from there - and might be detailed enough to tell you which
applications. (I've not seen the outpu
