06040: Monitor Latch Conflict Rate Exceeds Standard

    FILE:            IMS System Activity
    SAS FILE NAME:   DETAIL.IMSISY01
    SOURCE LOCATION: sharedprefix.MICS.SOURCE(DYIMSEXC)

    SEVERITY:        Warning       (SEVERITY='W')
    MANAGEMENT AREA: Performance   (MGMTAREA='PERFORMANCE')

    PURPOSE:  Identifies that the DC Monitor may be affecting
system performance.

    RATIONALE:  An abnormally high number here may represent
impact on the system from running the DC Monitor.  The latch
conflict results in an OS wait for the requesting task.
There is little remedy for this situation other than not
running the DC Monitor.  Only large values should be of
concern.

    DEFINITION:  This exception is detected when the monitor
latch conflict rate exceeds the installation-defined limit.

    EXCEPTION STATEMENTS:  The SAS statements identifying the
exception situation and describing the condition are stored
