Function: This report helps identify conditions that cause
batch job abends related to DASD space shortages.
These causes can include poor JCL parameters,
fragmented DASD space, or a shortage of free space
for certain departments or during certain time
periods. This report helps the Storage
Administrator focus on particular groups or users
that are having problems, or to identify specific
time periods in which problems are occurring.
This report helps the Capacity Planner calculate
the amount of human and machine 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.
Generation of the summary report is automatic.
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
be used to make sure abends are not occurring for
managed users, and to alter SMS parameters if
necessary.
COLUMN DESCRIPTIONS
Summary Group
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)
Recovery Elapsed Time
The total amount of elapsed time necessary for the
recovery process to complete for the jobs in this
group. This is defined as the sum of the
difference between the start time of the original
failing step and the start time of the recovery
step for all the jobs in this group. If no
recovery steps were found for any of the jobs in
this group, a value of zeros will be present.
Rerun Steps
The number of job steps (program executions) that
had to occur to effect the recovery process for
the failures within this group. This does not
include the original failing steps, but does
include the recovery steps, plus any steps that
ran during the recovery periods with the same
jobnames as the original failing jobs. This will
have a value of zero if no recovery steps were
found for any of the jobs in the group.
Rerun CPU Time
The amount of processor time (TCB plus SRB CPU
time) required to perform recovery all the
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.
Rerun EXCPs
The number of I/O requests issued to perform
recovery for this step. This includes the I/O
counts of the failing step, and the I/O used by
any steps running under the same job name during
the recovery period. It does not include the I/O
used by the recovery step. If no recovery step is
found, this only includes the I/O counts used by
the original failing step.
