06024: CIO Pool Current Use Exceeds Standard

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

    SEVERITY:        Impacting     (SEVERITY='I')
    MANAGEMENT AREA: Performance   (MGMTAREA='PERFORMANCE')

    PURPOSE:  Identifies that the CIO pool may require
    enlarging.

    RATIONALE:  Insufficient storage for this pool, which is
used to build incoming messages and by MFS for output
messages, can have severe performance implications.  The
number monitored is the percentage of the pool that current
use represents.  A number close to 100 % may indicate
insufficient pool size.  The only way to determine
sufficiency is to increase pool size until the current use
remains below the available pool size and this percentage
number decreases.

    DEFINITION:   This exception is detected when the CIO
current use percentage exceeds the installation-defined
limit.  It does not apply to IMS 4.1 and higher systems.

    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

  EXCDESC2='CIO POOL USE ='
           || PUT(X,7.2) || '% OF AVAILABLE POOL ';

    THRESHOLD MODIFICATION:      Modify the CIO pool
current-use-percentage to a value between 0 and 100.
