Error description

  • DB2 don't clock zIIP elig time on util end and that caused the
wrong data in SMF record 101 for QWACZIIP_ELIGIBLE.

Local fix

  • N/A

Problem summary

  • ****************************************************************
* USERS AFFECTED: All users of DB2 10 for z/OS utilizing       *
*                 zIIP processors.                             *
****************************************************************
* PROBLEM DESCRIPTION: Value QWACZIIP_ELIGIBLE in an           *
*                      IFCID accounting record can be          *
*                      incorrect.                              *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When an agent executes a utility, a call to record the stop of
accounting time executing that utility will not correctly obtain
the zIIP time of the CPU.  This incorrect value will then be
used in a calculation of QWACZIIP_ELIGIBLE for the subsequent
accounting record, resulting in incorrect values for
QWACZIIP_ELIGIBLE field.

This error could appear in any of these records: IFCID3,
IFCID148 and IFCID369

Problem conclusion

  • Correctly gather zIIP time information for agents executing
utilities.

Temporary fix
