From the description of the abend, if your user code runs as a jobstep in
something like a JES initiator, you will always be at risk from a prior batch
job performing an LXRES for PC-ss (without an initiator restart).
Admittedly this is rare as LXRES-issuing code normally runs as a started

I have a dataset that is allocated to multiple jobs but with a disp=shr
And I am getting contention messages MIM1039I I was always under the impression
That if the dataset was allocated with disp=shr
It could be used among multiple jobs
Without problems

Do you know if the dataset is being held by something other than your
batch jobs, with DISP=OLD? You should be able to use the ISPF DDLIST
command to find out who is holding the enqueue.

It seems long past time that we could document:
-- you may assume that run-length-encoding is available
-- you may assume that that approach requires no workarea.
Thus (especially once documented) there is no need to use CSRCESRV
SERVICE=QUERY.
Should some alternate algorithm be implemented, it
This abend is not about a separate started task that uses LXRES in its
creation of an XM environment, and then subsequent jobs or started tasks
"connect".
The description for this abend is this: LXRES is issued but a
cross-memory-resource-owning jobstep task has already terminated in the
home

That won't work if two jobs simultaneously try to write to the file.
You might not destroy the file, but you will lose the information
The chances of two jobs writing to the file are slim and none I am searching
a large number of files because I cannot find the data
And most importantly it is NOT a production job

We use BMC Mainview for z/OS, CICS, DB2 and Performance Reporter for DB2. These
related but separate products that BMC put under one SMPe FMID.
The issue we have is that one person does the z/os, cics part and I do the DB2
part. And this causes us to step on each other in terms of maintenance. Wh

Hello,
In past when we used CA-TLMS we have CA-COPYCAT utility that help in tape
duplication among other things.
Control-M/Tape has something similar to CA-Copycat?

Given an SMF record for DB2 (100-102), I'd like to find the DB2 version/release.
In the product section, I see QWHSRN and QWHSSUBV.
The first is the release "indicator number" in hex.
The second is the "subversion for the base release".
I downloaded SMF 9.1 data from IBM's secure site. That's what
According to the documentation, after z/OS 2.3 the LFAREA parameter no longer
reserves real memory for large frames at IPL. Instead, it's a limit on the
number of fixed 1M frames.
Since it's now a limit is there any harm in leaving LFAREA too high as long as
you keep an eye on large fixed fram
Your interpretation of QWHSRN is correct. It is the same place and format
through all recent and current versions AFAIK.

The only thing that has changed is the wording, before 2.3 (i.e. 2.2) it stated:
The IEASYSxx LFAREA parameter specifies the amount of real storage to be made
available for 1 MB and 2 GB large pages.
after 2.3 (i.e. 2.3 and 2.4) it now says:
