PK71063: STATISTICS REPORTED BY BATCH JOB THAT PRODUCES THE .BPD FILE INCONSISTENT WITH STATISTICS REPORTED BY BPA CLIENT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The statistics reported by the Batch job that creates the .BPD
  file are inconsistent with the numbers displayed in the reports
  on the client.  For example:
  *
  Report shows:
  System hit,ratio,              99.35
  Application hit ratio          99.87
  Getpage request                508213
  Sequential                    10904
  Random                        497309
  *
  The Client shows the following for ?getpage counters?
  Seq. Access  338
  RID List  2,408
  Rnd. Access  17,765
  Total:  20,511
  **
  The BPACTIVITY REPORT LEVEL(SHORT) generated on customer
  provided data has inconsistencies with data in .BPD file
  
  Also, the field "Delay(msec)", the I/O device delay in
  milliseconds, will be displayed correctly (current values are
  very high in some cases).

  PROBLEM SUMMARY:
  Previously used matching algorithm for IFCID 6 and 7 caused
  poor performance, storage overuse and inconsistensy in numbers
  seen in batch reports and PE Client. I/O Read numbers not always
  were quite correct.
  
  PROBLEM CONCLUSION:
  BPA code in charge of IFCID 6,7,8,9,10,198,202 processing has
  been reworked. Considerably improved performance on big amounts
  of input data, reduced storage footprint, improved Read numbers
  accuracy and provided consistency between REPORT and PE Client
  shown numbers.
