PM26109: ABENDS0E0-028 IN DFHRSXM, DFHRSDU DUE TO THE ACCESS REGS NOT BEING INITIALIZED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You are running an EXEC that initializes your ACCESS REGISTERs
  to X'FFFFFFFF'.  Because the RS domain does not initialize the
  AR's to zero, an ALET-specification exception can occur
  because X'FFFFFFFF' is not a valid DATASPACE address
  Additional Symptom(s) Search Keyword(s): DFHRS0001 DFHKE0201

Local fix

• Do not run the IEAINITARSRB exec
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICSPlex SM V4R1M0 Users                 *
  ****************************************************************
  * PROBLEM DESCRIPTION:    You have a CPSM WLM workload which   *
  *                      is configured to communicate region's   *
  *                      status information through a coupling   *
  *                      facility data table (Sysplex Optimized  *
  *                      Workload).  Your MASes experience S0E0  *
  *                      (ASRB) abends in one or more of modules *
  *                      DFHRSDU, DFHRSSM, DFHRSSR, and DFHRSXM. *
  ****************************************************************
  * RECOMMENDATION: After applying the PTF that resolves this    *
  *                 APAR, all CMASes and MASes must be recycled  *
  *                 to pick up the new code.  Note that restarts *
  *                 do not need to be done at the same time.     *
  ****************************************************************
     Subroutine copyrsb, called in several Region Status Domain
  modules to copy the contents of a MAS's Region Status Block to
  or from the WLM cache data space, does not initialize access
  registers used to address storage in the primary address space
  before attempting to copy the RSB.  If one or more access regi-
  sters contain nonzero ALETs, abend S0E0 (ASRB) may result when
  accessing a copy of the RSB in storage in the primary address
  space.
  

Problem conclusion

•    Subroutine copyrsb was modified to save access register
  contents and initialize access registers to zero on input,
  and to reload the contents before returning.
