PI14104: CPSM OVERLAY POSSIBLE IN WLM DATASPACE, OR POTENTIAL ASRA S0C4 IN EYU0WMUT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If the CPSM WLM cache extends to two dataspaces, the potential
  exists for a Workload Descriptor (EYURWRKD) and its default
  TRANGRP Descriptor (EYURWTGD) to end up in separate dataspaces.
  If the WLMAWORK view is then used to SET the algorithm type, an
  overlay or an ASRA/S0C4 may occur.

  ****************************************************************
  * PROBLEM DESCRIPTION: When the WLMAWORK resource table SET    *
  *                      action is used to change the "Default   *
  *                      algorithm type" attribute               *
  *                      (WLMAWORK_ALGTYPE), an overlay of WLM   *
  *                      dataspace storage or an S0C4 abend in   *
  *                      method EYU0WMUT (WMUT) may occur, if    *
  *                      the WLM data cache extends to two       *
  *                      dataspaces.                             *
  ****************************************************************
  * RECOMMENDATION: After applying the PTF that resolves this    *
  *                 APAR, all CMASes must be restarted.  Note    *
  *                 that the restarts do not need to occur at    *
  *                 the same time.                               *
  ****************************************************************
  When a SET action is issued against the WLMAWORK default
  algorithm type, WMUT loads the address of the default trangroup
  descriptor (EYURWTGD) from the workload descriptor (EYURWRKD).
  If the WLM data cache is extended to two dataspaces, and the
  EYURWRKD and EYURWTGD are not in the same dataspace, then the
  address loaded by WMUT will be invalid.  If the storage pointed
  to by the invalid address is allocated, an overlay will occur.
  If the storage is not allocated, a S0C4 will occur in WMUT.
  

Problem conclusion

• WMUT hs been updated to always load the address of the EYURWTGD
  correctly.
