Function:  This facility allows the storage administrator to
           monitor the day-to-day allocation of new data
           sets.  This permits early identification of groups
           or users that are allocating excessive space or
           using space incorrectly.  One of the most common
           causes of space shortages in a typical
           installation is the intentional or unintentional
           allocation of large new data sets.  These reports
           will help solve that type of problem, as new data
           sets occupying large amounts of space can be
           easily identified and corrected before they cause
           space shortages.

           The facility permits you to indicate which data
           sets are to be considered new for the purposes of
           the reports.  This option can help provide many
           different views of the same data.  For example,
           you could analyze all the data sets created
           yesterday to isolate problem data sets, or you
           could look at all data sets created in the last
           month to establish growth patterns for each
           department.

           Because this facility also supports input data
           describing the tapes in your tape library, the
           reports can also prove useful to those measuring
           the usage and growth of that resource.  Those
           persons responsible for tuning DFHSM or DFSMS can
           also benefit from running these reports with HSM
           input to determine how soon new data sets are
           migrated to HSM.

Features:  Summary reports can show new allocation
           trends based on volume serial number, volume group
           (or SMS storage group), system, SMS management
           class, SMS management class, one or more data set
           name nodes, one or more CA MICS accounting fields,
           or by using an external table of data set name
           patterns.  Each summary report can be produced as
           a tabular report, printer graphic report, or color
           graphic report.  Up to two different summary
           elements may be specified, to provide you with
           many different data views.

           If a summary report indicates a potential problem
           or anomaly, a detailed report can be produced to
           give more information about individual new data
           sets.  You can specify whether all new data sets
           should be listed or just the largest.  You can
           also specify whether the sort order of the detail
           report should be based on data set name or size.

           Data filtering allows you to include data from
           selected groups.  For example, you can choose to
           report on specific volumes, volume groups, or
           select new data sets allocated by only certain
           users or departments.

SMS
Issues:    The reports in this facility will help you
           maximize your storage usage while SMS
           implementation is taking place.  Even after SMS is
           fully implemented, poor allocation practices will
           still occur, as users can still override many of
           the SMS defaults.  The ability to monitor new data
           set activity by storage group, storage class or
           management class will also help you make sure your
           SMS system is working as designed.

           This report requires at least one summarization
           level, with a second one being optional.  If two
           levels are selected, the major level will appear
           at the top of each page, and the minor level will
           appear as the left-most column in each report.  If
           only one summarization level was specified, it
           will appear as the left-most column.  The
           description for each summary element will be one
           of those values shown above.  These values
           represent summarization by System Identifier
           (SYSID), SMS management class, SMS storage class,
           volume serial number, or volume group (or SMS
           storage group).  If the label "Owner" appears,
           this represents summarization based on one or more
           data set name nodes, one or more CA MICS
           accounting fields, or based on an external Data
           Set Group table.

    New Data Sets
           The number of new data sets found in the input
           data belonging to this summary group.  The age of
           a data set that is considered "new" is determined
           by the options you coded on the report options
           panel.

    % Data Sets New
           The percentage of all data sets found in the input
           data for this summary group that represent new
           data sets.  If 100 data sets were found for this
           group and 25 of them were new, this value would be
           25%.

    New Space (MB)
           The amount of storage space, expressed in
           megabytes, allocated by the new data sets found
           for this summary group.

    % Space New
           The percentage of all allocated space found in the
           input data for this summary group that represent
           space allocated by new data sets.  If all data
           sets in this group allocated 100 megabytes of
           space, and 40 of those megabytes were allocated by
           new data sets, this value would be 40%.

    Avg New Size (MB)
           The average amount of space allocated, expressed
           in megabytes, by the new data sets in this summary
           group.  This is calculated by dividing the total
           amount of space allocated by new data sets by the
           number of new data sets.

    Largest New Data Set Information:
           All of the items on the right side of this report
           refer to the largest data set found among all the
           new data sets in this summary group.

           Name
               Specifies the data set name of the largest new
               data set in this group.

           Space Alloc (MB)
               Specifies the amount of space allocated, in
               megabytes, by the largest new data set in this
               summary group.

           Volume Serial Number
               Specifies the volume on which the largest new
               data set in this summary group resides.
