PQ91285: QM is understating both synchronous and other i/o delay times in comparison with SMF data.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• QM is understating both synchronous and other i/o delay times in
  comparison with SMF data.
  For example, the following information did not match for a
  particular DB2 batch job:
  1) CPU TIMES:
  Elapsed time
  CPU time
  Delay
  Lock.Latch delays
  Synchronous I/O del.
  Other read delays
  Other write delays
  service tasks switch
  2) Counts:
  # Calls
  service tasks switch
  Async page read
  KEYWORDS:
  Incorrect output
