Dear all,
I am a DB2 specialist , doing some measurements i just noticed that there is a
noticeable difference between DB2 CPU times i got from SMF30, and the times i
got from the DB2 statistics records (SMF100) about the CPU consumption of DB2
address spaces. I submitted the question to

Yes, if we had the time, we would rewrite the job to use the output from
IRRDBU00 instead of parsing LU * output. We'll probably have the time when IBM
changes the output, of course. :-)
In any case, thanks to those who made suggestions here and off-list. The
problem does appear to be in

Is there a mailing list for CA Top Secret?
Alternatively, is ACF2-L suitable for TSS questions?

At one time there was a sprinkling of traffic on this list, maybe 10 per
month. I haven't seen any in a long time so I'd probably utilize
IBM-MAIN for TS issues.
I'd avoid RACF-L unless the issue has a direct relationship to RACF,
i.e. conversion or dual/hybrid administration.

Multiple ways, but I would probably just use D XCF. If you are looking
for a TSO command, you need something home grown to look at symbols

There is a basic issue with DB2 statistics for CPU - they start with the
first SQL statement. Everything that happens before that is not recorded
in the DB2 cpu times. This is WAD. There used to be some presentations on
what was included in DB2 cpu and why. I haven't looked for them in a long
In general, there will be very little CPU time recorded in the DB2 Address
Spaces,
except for the DDR address space, because CPU time consumed in DB2 is recorded
in

called DB2, so the SMF 101 (DB2ACCT) data is the only

This is a snapshot of a paper I wrote a couple of years ago.

using SMF 100 are just a little bit lower than using SMF 30 OR 72.

Hi All,
Since you mentioned the z/OS V2,1 Migration book being available, I thought I
would bring to your attention something. It's different.
We've tried a new format for the book, which I'm hoping will make it easier to

No, we have only one LPAR.
1) Do you have SETROPTS INACTIVE set and to what number of days?

correct and it is easy to just run the configuration, etc., the work I've done

The migration specific format is nice, however, for online reading the dual
