PH21109: DFH0STAT ABENDS AEIP IF HOURGLASS USED TO ADJUST THE TIME BACKWARD

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• With CICS TS 5.4 and 5.5 onward, DFH0STAT fails with an
  ABENDAEIP when a customer uses the Hourglass product to adjust
  the time backward, due to DFH0STAT attempting to format a
  negative time value. This started occurring because of the use
  of the  EXEC CICS EXTRACT STATISTICS LASTRESETABS command in
  DFH0STAT. LASTRESETABS was introduced in CICS TS 5.4.
  This APAR will change DFH0STAT so that it does not attempt to
  format a negative time value and so avoid the abend.
  

Local fix

• Modify DFH0STAT to not issue the failing EXTRACT command.

  ****************************************************************
  * PROBLEM DESCRIPTION: DFH0STAT ABENDs AEIP when the elapsed   *
  *                      time calculated by subtracting the last *
  *                      statistical reset time from the current *
  *                      time is negative.                       *
  ****************************************************************
  DFH0STAT ABENDs AEIP when receiving INVREQ in an attempt to
  use FORMATTIME with a negative time value.
  The elapsed time calculated by subtracting the last
  statistics reset time from the current time can be negative
  after a clock change or when running with a simulated date and
  time as may be provided by HOURGLASS or a similar product.
  

Problem conclusion

• DFH0STAT and DFH0STSY are amended to assume an elapsed time of
  zero when the calculated time is negative. This will avoid the
  AEIP ABEND but statistical values that rely on the elapsed time
  since the last reset, for example counts per second, will be
  unreliable.
