<h1 class="topictitle1">Subsystem description</h1>
|
||
|
|
<div><p>A subsystem description is a system object that contains information
|
||
|
|
defining the characteristics of an operating environment controlled by the
|
||
|
|
system. 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.</p>
|
||
|
|
<p> Like a set of detailed blueprints, each subsystem description is unique,
|
||
|
|
containing the specific characteristics that describe the subsystem.
|
||
|
|
The description includes where work can enter the subsystem, how much work
|
||
|
|
the subsystem can handle, how much main storage (memory) will be used, and
|
||
|
|
how quickly jobs in the subsystem can run. </p>
|
||
|
|
<p>You can use a subsystem description supplied with your system (with or
|
||
|
|
without making changes to it), or you can create your own. </p>

||

<li class="ulchildlink"><strong><a href="rzaksaboutsbsdattributes.htm">Subsystem description attributes</a></strong><br />
|
||
|
|
Subsystem description attributes are common overall system attributes. When you create a subsystem, the first step is to define the subsystem attributes.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzaksaboutworkentries.htm">Work entries</a></strong><br />
|
||
|
|
Work entries identify the sources where jobs can enter a subsystem. Specific types of work entries are used for different types of jobs. Work entries are part of the subsystem description.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzaksaboutroutingentries.htm">Routing entries</a></strong><br />
|
||
|
|
The routing entry identifies the main storage subsystem pool to use, the controlling program to run (typically the system-supplied program QCMD), and additional run-time information (stored in the class object). Routing entries are stored in the subsystem description.</li>
