<div class="section"><h4 class="sectiontitle">Base memory pool example</h4><p>Two subsystems, SBSA and
|
||
|
|
SBSB, use the Base memory pool to run jobs. SBSA currently has two jobs running
|
||
|
|
in this memory pool and SBSB has one. A job queue entry in the subsystem description
|
||
|
|
for SBSB specifies that any number of jobs can be started. The activity level
|
||
|
|
of the Base memory pool is 3. Therefore, only three jobs in the
|
||
|
|
Base memory pool can compete for the processing unit at a time. However, all
|
||
|
|
of the jobs are started.</p>

<div class="section"><h4 class="sectiontitle">Four jobs in a subsystem example</h4><p>One autostart job,
|
||
|
|
two workstation jobs, and one batch job (four jobs in all) are in subsystem
|
||
|
|
SBSC. The MAXACT for SBSC is specified as 4. No matter what is specified for
|
||
|
|
the MAXACT of the work entries, no other jobs can be started until at least
|
||
|
|
one job completes running. </p>
|
||

|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Batch subsystem MAXACT(1) example</h4><p>Subsystem SBSE
|
||
|
|
is a batch subsystem for which 1 is specified for MAXACT. Although the job
|
||
|
|
queue entry does not specify MAXACT, the limit is one job because 1 is specified
|
||
|
|
for MAXACT for the subsystem. Therefore, jobs are processed in job priority
|
||
|
|
one at a time off the job queue.</p>
