Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• During an UNLOAD with UK80678 on, an abend0c4 occurs in module
  DSNUUSEL offset 0142, x'0142'. The UNLOAD used a WHEN along
  with partition parallelism
  Additional Keywords:
  s00c4 00c4 0c4
  

Local fix

• Do not use UNLOAD WHEN with partition parallelism
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All DB2 10 for z/OS utility users of UNLOAD  *
  *                 WHEN with partition parallelism active and   *
  *                 with PM65550 / UK80678 applied.              *
  ****************************************************************
  * PROBLEM DESCRIPTION: After applying PM65550 / UK80678,       *
  *                      an ABEND0C4 DSNUUSEL OFFSET0142 can     *
  *                      occur when running an UNLOAD with a     *
  *                      WHEN clause and partition parallelism   *
  *                      active.                                 *
  ****************************************************************
  * RECOMMENDATION: Apply corrective PTF when available.         *
  ****************************************************************
  After applying PM65550 / UK80678 an ABENDS0C4 DSNUUSEL + x'0142'
  can occur when running an UNLOAD with a WHEN clause and
  partition parallelism active.  The problem occurs when the
  number of subtasks does not match the number of partitions being
  unloaded, resulting in an internal control structure not getting
  setup correctly.
  

Problem conclusion

• UNLOAD WHEN with partition parallelism active has been changed
  to initialize the internal control structure for all partitions
  being unloaded.
  

Temporary fix
