Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Db2 Query Monitor                   *
  ****************************************************************
  * PROBLEM DESCRIPTION: Intermittent high GETPAGE totals seen   *
  *                      in some workloads                       *
  ****************************************************************
  * RECOMMENDATION: Apply the PTF                                *
  ****************************************************************
  If the DB2 BBRY accounting area field for a thread exceeds
  7FFFFFF CQM must handle this to prevent a negative number from
  being added to total GETPAGES which can result in a display of
  an extremely large number.
  

Problem conclusion

• CQM updated to validate special conditions in its own field and
  in the DB2 BBRY field to avoid a negative number calculation.
  

Temporary fix
