PK27615: ABEND0C4 OR MSGIEC036I 002-18 IN HPFP REORG UNLOAD PROCESS

APAR status

• Closed as program error.

Error description

• When HPFP Reorganization Unload runs with multiple
  IAREA/OAREA in restructure mode, it may get ABENDS0C4 or
  IEC0036I. This problem occurs in multiple CPUs.
  S0C4 can occur in HFPJINI0, HFPJIUS0, HFPJOMN0, and HFPJQUS0.

  ****************************************************************
  This APAR includes the following 3 problems.
  1. The following situations occur when unloading multiple areas
     by a multiprocessing configuration with both IMSACB and
     NEWACB.
     * Abend S0C4 in HFPJINI0, HFPJIUS0, HFPJOMN0, HFPJQUS0 or
       HFPJUSR0.
     * Issue MSGIEC036I 002-18 and abend S002 in IFG0199B.
  2. Analyze process estimates and allocates HFPSxxxx for the
     internal usages dynamically. The estimated size is too big
     to allocate the HFPSxxxx data set.
  3. When reload and change process are run with ALLOCATE
     ATTRIBUTE=(IDCAMS,..) and the IDCAMS statement has some
     errors, it may abend HFPU4000E INTERNAL ERROR FOUND.
  

Problem conclusion

• This APAR solves the following 3 problems.
  1. HPFP Reorg does not care about Free-Pool manipulation at the
  system with multi-CPU, high CPU speed and high CPU utilization.
  When unloading multiple areas by a multiprocessing
  configuration, the abend resulted from a buffer breakdown.
  It has been modified to append to the header a counter.
  2. Analyze process has been changed to estimate HFPSxxxx data
  set size appropriately.
  3. Reload and Change processes have been modified to manage
  IDCAMS statement errors in spite of MAXCC statement.
