  * USERS AFFECTED: Users of IBM Db2 Query Monitor z/OS.         *
  ****************************************************************
  * PROBLEM DESCRIPTION: When the number of getpages exceeds     *
  *                      2Gb value, the display is incorrect in  *
  *                      Current Activity and Summary screens    *
  *                      in ISPF, CAE and e3270UI (OMEGAMON      *
  *                      integration). Incorrect values were     *
  *                      also for AVG getpages.                  *
  ****************************************************************
  * RECOMMENDATION: APPLY the PTF.                               *
  ****************************************************************
  Due to incorrect algorithm when the number of getpages exceeds
  2Gb value:
  1. in Current Activity the calculation starts from the
   beginning.
  2. in Summary the number of getpages and AVG getpages are zero.
  3. The CAE on the corresponding panels shows negative values
   which are going towards zero. After reaching zero the
    calculation starts from the beginning.
  

Problem conclusion

• Algorithm is fixed so that values larger than 2 Gb are
  displayed correctly.
  
  Please note that for Current Activity the limit of displaying
  is 4Gb, as Db2 does not provide larger values for running
  threads and start counting from the very beginning after
  reaching 4 Gb.
