06006: Message Queue Dequeue 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 the time period during which the
message queue pool was over-utilized.

    RATIONALE:  An abnormally high message queue pool dequeue
rate indicates over-commitment of the message queue pool.
This may be caused by a message generating BMP or user misuse
of transactions.  System performance is extremely sensitive
to activity in this pool.  This number is affected by the
complexity of message traffic as well as volume.

    DEFINITION:  This exception is detected when the message
dequeue rate exceeds the installation-defined limit.

    EXCEPTION STATEMENTS:  The SAS statements identifying the
exception situation and describing the condition are stored
in the source member named in SOURCE LOCATION and are
