Problem summary


    

  • ****************************************************************
* USERS AFFECTED: Users of IMS Performance Analyzer V4.4       *
****************************************************************
* PROBLEM DESCRIPTION: Incorrect data in IRUR Logger Report    *
****************************************************************
1. Maximum I/O times are correct, but the timestamps that
   should match those values are incorrect.

2. Timestamps are adjusted for Timezone offset, but not Leap
   Second offset.

    



Problem conclusion


    

  • 1. Max I/O timestamps are corrected to reflect the time of
   the Max I/O value.

2. Timestamps are adjusted for both TZO and LSO values from
   the IMS x'4500' record.

3. Several other issues addressed, including:
     Latch statistics were not correctly initialized,
     resulting in some incorrect values.
     TCB statistics percentage value calculations corrected.
     Some very large numbers were incorrectly formatted
     leading to overflows or incorrect results, which are
     now corrected.
     Sundry formatting corrections.
