PM18104: CICS CMAS REGION SOS. BUILDUP IN SMSHRC31 STORAGE.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Your CMAS region goes SOS above the line, possibly receiving a
  DFHSM0133 message.  An SVC dump of the region shows the ECDSA
  has most of the EDSA storage, but many of the extents are nearly
  empty. In each extent, there may be a few pages of storage in
  the SMSHRC31 subpool.
  .
  The SCE control block for these pieces of storage may show a
  buildup of pieces x'470' bytes in length.
  .
  Formatting out the trace table using
    VERBX EYU9D410 'TRC,JOB=cmasjobname'
  You will find a number of exception traces with Debug text of
  XDOL_1 and Point-Id of 27.  The CPSM Trace Record Storage will
  show a request being made against the WLMAWAOR base table.
  .
  Additional Symptoms: You may also notice a buildup of SCE
  control blocks for x'110' bytes. Those contain MAL's for
  transactions which have not been able to run due to the SOS
  condition.  Formatting out the Interval Control domain you would
  see a correspondingly large number of tasks that are waiting to
  run as soon as the SOS has been relieved. These control blocks
  will be FREEMAIN'd when the SOS-delayed transactions are run.

  ****************************************************************
     Module EYU0XDP1 (XDP1 - API Get Processor) calls EYU0XDOL
  (XDOL - MOS Filter Compiler) to generate a usable query module
  from a passed CRITERIA string.  XDOL is called once to build a
  filter at the serving CMAS's version.  If an abnormal status is
  returned, then a second call is made to XDOL, passing the API
  CONNECT version.
     If the targeted resource is associated with an active work-
  load, XDOL also returns the name of the WLM Set which identifies
  the workload.  If the name of the workload is part of the passed
  CRITERIA, it is placed in the WLM Set name.  Otherwise, a status
  of XDOL_CRITERIA_MISSING_WORKLOAD is returned but the filter and
  query module are built normally.  However XDP1 interprets the
  non-OK status as an indication that the filter was not built,
  and repeats the call to XDOL passing the API CONNECT version,
  orphaning the filter and query module built by the first call.
  

Problem conclusion

•    Module EYU0XDP1 was modified to accept a returned status of
  XDOL_CRITERIA_MISSING_WORKLOAD as normal, and to use the filter
  and query module built by XDOL.  The filter will be discarded
  after the result set has been built.
