I have an issue where an STC holds a VSAM Dataset. The STC is a scheduling

Once per day we close and free the VSAM file from the STC, run an archive
process and then re-open then file to the STC.
This works nearly all of the time. However, on occasion (a couple times a year)
the job will fail in the IDCAMS Step with DATASET IN USE BY ANOTHER TASK
message. The enq is so fast, I do not have any indication of what was holding
it.
The IDCAMS Step reloads the history file with the last 3 days' worth of
information about jobs. It is a very simple
REPO IFILE(x) OFILE(y)
I opened an SR to IBM DFSMS and asked if they could add some checks in IDCAMS
for the nonzero return code from the enq and let me know what job is using it.
They indicated that extra code path to do that would not help. They felt that
the enq is released so soon the extra test for the enqueue would not provide the
name of the task.
I have looked at RMF reports - I could see nothing.
I have looked at DAF reports for the 5 min time frame - I could see nothing.
When the step fails with RC12, I do the D GRS,C and nothing shows up.
I am tempted to start the ISG Monitor for Enqueues for the 15 minute window when
this job runs.
Lizette,
Run the GRS Monitor, you'll get your answer.
