PM49886: ABEND0C1 FOLLOWED BY ABEND0C4 IN DSNUGSTA +1D48 AND DSNUSTBL +19AC WHEN RUNNING REORG UTILITY WITH PARALLEL UNLOAD/RELOAD

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Reorg utility using unload/reload paralleism (MSGDSNU1160I
  issued) might get multiple abends, like abend0C1 or abend0C4
  in csects like DSNUGSTA or DSNUSTBL, followed by abend04E
  RC00E20005 in 0E20005 DSNSVBK +1AB6 (caller: DSNIDALC) due
  to storage overlays .
  The occurrence and extent of the storage overlay is definitely
  data dependent and depends on the size of a pre-existing storage
  area and the size of the data records being processed.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All DB2 9 for z/OS and DB2 10 for z/OS users *
  *                 of REORG TABLESPACE utility.                 *
  ****************************************************************
  * PROBLEM DESCRIPTION: REORG TABLESPACE with parallel unload/  *
  *                      reload processing failed with ABEND0C4  *
  *                      in DSNUGSTA + x'1D48'                   *
  ****************************************************************
  * RECOMMENDATION: Apply corrective PTF when available.         *
  ****************************************************************
  User ran a REORG TABLESPACE that utilized unload/reload
  partition parallelism (i.e. MSGDSNU1160I issued).  The utility
  failed with ABENDS0C4 in DSNUGSTA +x'1D48' in the RELOAD phase
  due to a storage overlay on one of the work areas, which was
  caused by incorrect program logic in not validating the work
  area was of sufficient size before it was used.
  
  Additional symptoms:
  
  - ABEND0C1 ABENDS0C1
  - ABEND0C4 in DSNUSTBL + x'19AC' , +x'19AC'
  - ABEND04E RC00E20005 in DSNSVBK + x'1AB6' , +x'1AB6'
  

Problem conclusion

• Code has been modified to ensure the aforementioned work area
  is allocated with sufficient size before its usage.
