Function: This chart helps identify the amount of CPU time
being expended in recovery activities for job
abends related to DASD space shortages. These
shortages can be caused by poor JCL parameters, by
fragmented DASD space, or by a shortage of free
space for certain departments or during certain
time periods. This report gives the Storage
Administrator a broad overview of the groups or
users that are having problems, and helps identify
specific time periods in which problems occur.
This chart helps the Capacity Planner calculate the
amount of processor resources wasted in recovery
activities.
Features: The detection and calculation of resources expended
doing recovery activities could save much
time-consuming manual research. A wide variety of
filtering and reporting options allow many views of
the data, such as a broad system-wide view, a
narrow view related to an individual time or
department, or a view of a specific time period.
This report could be run on a daily basis to give a
general indication of storage system health. On
days when anomalies occur, running the Allocations
Problems analyses again with more detailed options
could help isolate the problem. Both color
graphics and printer graphics are supported by the
report.
SMS
Issues: Users implementing SMS may want to identify
departments having space-related abends as
potential candidates for movement to SMS Storage
Groups. After SMS is implemented, this report can
help make sure abends are not occurring for
managed users, and to alter SMS parameters if
necessary.
COLUMN DESCRIPTIONS
Pie Slices
The pie slices represent the total amount of
processor time (TCB plus SRB CPU time) required to
perform recovery for all the space-related failures
within this group. This includes the CPU time of
the failing steps, and the CPU time used by any
steps running under the same job names during the
recovery period. It does not include the CPU time
used by the recovery steps. If no recovery steps
are found for the jobs in this group, this will
only include the CPU time used by the original
failing steps.
Pie Labels
The labels on each slice identify the name of the
group for which this summarization was performed.
Depending on the values coded on the report option
panel, this value can represent one or more of the
BATPGM file accounting fields, or can be one of the
following:
JOBCLASS = (Summary by Job Class of failing jobs)
ZONE = (Summary by ZONE of the failing jobs)
HOUR = (Summary by Hour of the failing jobs)
TYPE = (Summary by space-related abend type)
