Error description

  • This enhancement adds the ability to leverage advice from IBM
    DB2 Query Monitor via a new exception/symptom called REORG
    AVOIDANCE.  A new entity called a Performance Window will
    provide start/end timestamps for CQM to monitor SQL that runs
    within that performance window against any object contained in
    the HAA object profile being processed.  Over time, CQM can
    detect performance degradation in the SQL being recorded.
    Should HAA exceptions recommend a REORG, the REORG can be
    avoided when:
    .
     1) the REORG AVOIDANCE exception is selected
     2) the SQL that CQM has recorded shows little indication of
        performance degradation.
