PM74413: ABEND0C4 IN DSNIOST2 ON A SYSPLEX QUERY PARALLELISM CHILD TASK.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Dump Title: DBAD,ABND=0C4-00000010,U=BATPIW  ,M=N  ,C=101.DMC
  -DSNIST2O,M=DSNTFRCV,LOC=DSNIDM  .DSNIOST2+2C12
  A sysplex query parallelism child task issued ABEND0C4 in
  DSNIOST2 because MSIDMSPROC was incorrect.
  It looks like the MSIDMSPROC was set by the parent task in
  another member to point its SPROC when the MSIB was used by the
  parent task.
  But the SPROC was not accessible by the child tasks in other
  members.
  The MSIDMSPROC should have been cleared before copying the MSIB
  for child tasks.
  

Local fix

• Disable sysplex query parallelism.

  * RECOMMENDATION:                                              *
  ****************************************************************
  ABEND0C4 RC04 at DSNIOST2+2C12 can occur for a query that is run
  with sysplex parallelism.  The abend is caused by a residual
  SPROC address which missed the cleanup while creating a child
  task in the local DB2 system.
  

Problem conclusion

• DB2 code is modified to clean up residual addresses for SPROC
  and PPROC while starting the child task.
  

Temporary fix
