09010: Data Set Using Less than n% of Allocated Space

    FILE:             DAA Data Set Allocation File
    SAS FILE NAME:    DETAIL.VCADAA01
    SOURCE LOCATION:  prefix.MICS.USER.SOURCE(DYVCAEXC)

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

    PURPOSE:  Identifies when a large data set is
over-allocated.

    RATIONALE:  Inefficient use of DASD space can impact the
installation's ability to satisfy future DASD space requests.
Large data sets that are static in nature should be
allocated such that most of the space allocated is being
used.  If these data sets are over-allocated, the unused
space is not available for use.

    DEFINITION:  This exception is detected when the data
set's allocation exceeds the specified value and the percent
of allocated space in use falls below the specified minimum.

    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
described below:

END;

    THRESHOLD MODIFICATION:  The user should modify the
percent and space values according to the following
conventions:

    percent - The minimum acceptable value of allocated space
         that is in use.  A minimum space utilization of 40
         percent would be specified as:

         PERCENT = 40;

    spaca - The number of allocated tracks that is considered
         a large allocation.  An allocation of 1000 tracks
         would be specified as:

         SPACA = 1000;
