update IEF033I message to include ZIIP usage time

Hello IBM, can I please for a change to message IEF033I as follows to allow the ZIIP time to be shown. This would be a small however important improvement scanning out batch jobs for ZIIP consumption. IEF033I JOB/QR2DAP49/STOP 2024008.0622 CPU: 1 ...

Extracting SMF in a single job step with a single pass of data

If I want to dump multiple different timeframes of data into an smf dataset I have to do it in multiple steps and mod'ing onto the output dataset For example if I want Type14 records from 2200 on 1st Jan to 06:00 on 3rd Jan I would have to do this...

switch from IEFUSI to SMFLIM

Hi IBM, today we use IEFUSI to adjust Region Limit and Region Size for z/OS Address Spaces.With this Exit, we also make sure that we have a sufficiently large difference between Region Limit (LDALIMIT/LDAELIM) and Region Size (LDAVVRG/LDAEVVRG). z...

Enhance message IFA016I with the root cause

There are numerous reasons a SMF dump program IFASMFDP USER exit might not be available, but the IFA016I message is a catch-all / generic message that does not provide any useful information (outside of an abend issue) which the user can use to di...

Replace some of the basic IEFUTL functionality with PARMLIB parameters

Everyone is trying to reduce their reliance on assembler exits due to the lack of assembler resource available these days. We use IEFUTL to override when batch jobs are cancelled by the JWT parameter in SMFPRMxx and nothing more. I'm sure it would...

IFASMFDL DUMP start date time window

While switching from SMF dataset mode to logstream mode, we noticed that IFASMFDP (dataset mode) behaves differently than IFASMFDL (logstream) wrt the date/time windows:- IFASMFDP allows to dump records from start date "-1"/time "xx:xx" up until e...

SMF Record for dataset allocation

If a dataset is allocated by a DD statement in a batch job and never opened, the dataset is allocated for the duration of the job step however no SMF record is cut.

IFASMFDL RC=8 when error in LOGSTREAM

When there is an error when reading the LOGSTREAM, so that it is not safe that all requested data is present, the return code should be 8 instead of 4 because RC=4 indicate only a warning.RC=8 indicate an error. In our case we got a MSG 'IFA819I E...
