PK82861: THE DEDB AREA ANALYSIS REPORT INCORRECTLY REPORTS THE STANDARD DEVIATION FIELDS AS ZERO AT TIMES

APAR status

• Closed as program error.

Error description

• The DEDB AREA ANALYSIS REPORT as run via the DEDB Pointer
  Checker, can incorrectly report 0 for the SDEV and S/D
  standard deviation fields. This occurs even after PK63679
  is installed.

  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  Before the calculation of the standard deviation,
  the DEDB Pointer Checker checked whether this calculation is
  required. The calculation was skipped in case of sdev=0 and
  SDEV was set to 0.
  When the distributed value for the standard deviation is very
  small, the standard deviation value (SDEV and S/D) shows 0
  incorrectly due to the checking logic error.
  

Problem conclusion

• The macro DA5SDEV0 and DA5PRPR0 have been modified to remove
  the prior checking for the calculation of the standard
  deviation.
