<div><p>Subsystem description attributes are common overall system attributes.
|
||
|
|
When you create a subsystem, the first step is to define the subsystem attributes.</p>
|
||
|
|
<p>Subsystem attributes include:</p>
|
||
|
|
<ul><li>The name of the subsystem description and the library where it is stored</li>
|
||
|
|
<li>All of the memory pool definitions that this subsystem uses<p>A subsystem
|
||
|
|
definition can have a maximum of 10 memory pool definitions specified. Included
|
||
|
|
in the subsystem definition are:</p>
|
||
|
|
<ul><li>Pool definition identifier: This is the identifier inside the subsystem
|
||
|
|
description, of the storage pool definition.</li>
|
||
|
|
<li>Size: This is the size of the storage pool expressed in KB (1K=1024 bytes)
|
||
|
|
multiples and is the amount of main storage that the pool can
|
||
|
|
use.</li>
|
||
|
|
<li>Activity level: This is the maximum number of threads that can run at
|
||
|
|
the same time in the pool.</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>The maximum number of jobs that can be active in the subsystem at the
|
||
|
|
same time</li>
|
||
|
|
<li>A text description of the subsystem description</li>
|
||
|
|
<li>The name and library of the signon display file that is used to show signon
|
||
|
|
displays at work stations that are allocated to the subsystem</li>
|
||
|
|
<li>A subsystem library name that you can use if you want to specify a library
|
||
|
|
that should be entered ahead of other libraries in the system portion of
|
||
|
|
the library list (This parameter allows you to use a secondary language library.)</li>
|
||
|
|
</ul>
|
||
|
|
<p>Also included in the subsystem description is information about authority
|
||
|
|
levels to the subsystem. This information is kept by Security and is not stored
|
||
|
|
with the other attributes of the subsystem description. You can view the subsystem
|
||
|
|
description authority by using the Display Object Authority (<span class="cmdname">DSPOBJAUT</span>)
|
||
|
|
command.</p>

The system-recognized identifier for the object type is *SBSD. A subsystem description defines how, where, and how much work enters a subsystem, and which resources the subsystem uses to perform the work. An active subsystem takes on the simple name of the subsystem description.">Subsystem description</a></div>
