06037: Storage Mgt 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 latch processing may be over-
committed.

    RATIONALE:  An abnormally high number here may represent
resource over-utilization.  There is little remedy for this
situation other than reducing the number of PSTs or
decreasing the time required for processing via hardware
changes.  Only large values should be of concern.

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

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