06022: PSB Pool Current Use Mark 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 PSB pool may require
    enlarging.

    RATIONALE:  Insufficient storage for this pool, which
contains all non-resident PSBs, will cause ACBLIB I/O's for
the PSBs which are flushed for insufficient space in this
pool.  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 PSB
current use percentage exceeds the installation-defined
limit.

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

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