|
||
|
|
<div><p>The Concurrent Batch Job Statistics section of the Job summary
|
||
|
|
report shows information on the batch job workload during the trace period
|
||
|
|
according to job sets.</p>
|
||
|
|
<p>By looking at the first lines for a particular priority, you can quickly
|
||
|
|
determine if the system was fully utilizing all available batch activity levels
|
||
|
|
during the trace period.</p>
|
||
|
|
<p>Collection Services begins identifying concurrent jobs when it starts collecting
|
||
|
|
data. All jobs that are currently active are assigned to a job set. There
|
||
|
|
will often be several jobs that are continuously active during the trace period,
|
||
|
|
such as an autostart job for SNADS.</p>
|
||
|
|
<p>If another job starts during the trace period and none of the original
|
||
|
|
jobs have ended, it is assigned to a new job set. If a job ends and another
|
||
|
|
job of the same priority starts, the new job is considered to be a second
|
||
|
|
job in the same job set. For example, if the job queue entry for QBATCH has
|
||
|
|
a MAXACT parameter of 3 and you submit 8 jobs to QBATCH during the trace period,
|
||
|
|
there will probably be 3 job sets on the report with a total of 8 jobs shared
|
||
|
|
between them.</p>
|
||
|
|
<p>The job sets are sorted by job priority. Thus, for the above example where
|
||
|
|
the first job set was running for a total of 8 minutes and 50 seconds and
|
||
|
|
the second job set was running for a total of 6 minutes and 55 seconds, the
|
||
|
|
order of reporting shows the statistics for the second job set, then the third,
|
||
|
|
and then the first and assigns them sequential numbers.</p>
