PI22615: ROLLUP ACCOUNTING RECORDS (FOR REASON QWACRSTL / QWACRSTG ) NOT ALWAYS WRITTEN WHEN TRACE IS QUALIFIED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When using a filter on the accounting trace (eg. -STA TRA(A)
  PLAN(DISTSERV) ) together with rollup accounting ( ACCUMACC > 1
  ), accounting records ( IFCID3 ) are not always written when
  the record is written for reason staleness ( QWACRSTL ) or
  storage ( QWACRSTG )  ( QWACRINV = 3 or 2 ).
  

Local fix

• Don't qualify the accounting trace

  1. During retrieval of accounting records (IFCID0003), some
  records were not being produced and instead were being filtered
  out during the qualification process.
  .
  DB2 v10 has internal blocks for accounting trace records that
  were moved above the bar while the code was still looking into
  the previous storage area. When looking into the incorrect
  area, some SMF records may look to be QWACRSTG or QWACRSTL and
  caused DB2 to skip these records.
  .
  2. QWACPACE is used as the token to correlate a parallel,
  utility subtask or autonomous transaction rollup record. When
  DB2 v10 code looked at the previous storage area as detailed
  in section 1, QWHCAACE can report the token of the current
  running task, instead of the correct QWACPACE expected.
  

Problem conclusion

• SOLUTION: DB2 has been modified to address the correct block
  for properly qualified records and report the correct
  token to correlate.
