Tape library information (external)
Function: Expands on the information in the summary report,
identifying the range of space being allocated by
the non-VSAM data sets within an identified group.
Once you have identified groups of data sets with
common attributes, it is often useful to determine
the amount of space they represent, and the range
of that space allocation.
Features: Identification of size patterns within common data
set groups can help when calculating current
utilization or planning for future growth.
This report can also help identify exceptional
data sets that are improperly sized for the
function they perform.
Color graphics is supported.
Generation of this report is optional, as only the
summary report is produced automatically.
SMS
Issues: Just as the summary report helps identify
potential for SMS data classes, this report helps
you determine the default amount of space that
should be allocated by each of those classes.
This will allow your data classes to be
established faster, and with less chance of error.
COLUMN DESCRIPTIONS
Report Group
Identifies the reporting group for which this
chart is produced. Refer back to the summary
report to determine the group of data sets that
comprise this report group. A separate chart is
produced for each summary group, so that
allocation trends for common groups of data sets
can be identified.
Vertical Axis
The vertical axis of the chart represents a list
of allocation values ranging from 100 kilobytes
(thousand bytes) to 50000 kilobytes.
Horizontal Axis
The horizontal axis represents the cumulative
number of data sets found within each allocation
range. As this is a cumulative value, the chart
line should grow longer as it moves down the page,
representing almost all the data sets analyzed as
it reaches the bottom.
Other
The numeric values to the right of each chart line
represent the number of data sets in each range,
the cumulative number, the percent of all data
sets within each range, and the cumulative
percentage.
