APAR status

• Closed as program error.

Error description

• You recently upgraded to CPSM 5.2. Your CMAS starts
  successfully, but when you begin CONNECTing MASes to it, and
  CPSM goes to install workloads, you see an ASRA S0C4 abend in
  the CMAS. Messages may look similar to the following:

  In the dump, the CMAS trace table shows an exception trace
  entry for the following:
  .
  Task  Mtd  Prev Tran Obj Level Pt-ID  Debug  UOW   Local TOD
  12345 WMGL      WMWC     Abend       *Abend*     hh:mm:ss.ttttt
  .
  Bits 16-17 of the PSW are x'01', so we were in AR mode at the
  time.
  .
  The instructions in WMGL at +x'9DA' that we were in at the time
  show us at label ACQSYS_INCR. The problem is that AR8 is not
  pointing to the correct ALET for the WLM dataspace it needs to
  use. The instruction being executed at the time uses AR7 and
  AR8. The alet in AR8 is not for the correct WLM dataspace
  extent.

Local fix

• Recycling the CMAS may correct this, but the problem may
  reoccur on a subsequent run as well.

  *                 the same time.                               *
  ****************************************************************
  When a workload is installed, or a WLMDEF is installed into an
  existing workload, method EYU0WMGL (WMGL) is called to build
  EYURWSGA data structures in the WLM data cache for each
  AORSCOPE.  It then anchors the pointer to the EYURWSGA in the
  EYURWSGV data structure in the WLM data space and increments a
  AORSCOPE counter in the EYURWSGV header.  When it addresses the
  EYURWSGV header, it does so with the ALET of the EYURWSGA,
  instead of the ALET for the EYURWSGV.  If these structures
  reside in different data spaces, then the errors described above
  will occur.
  

Problem conclusion

• WMGL has been updated to correctly use the ALET for the EYURWSGV
  when updating the AORSCOPE counter.
