<div><p>One subsystem, called a <dfn class="term">controlling subsystem</dfn>, starts
|
||
|
|
automatically when you load the server. Two controlling subsystem configurations
|
||
|
|
are supplied by IBM<sup>®</sup>.</p>
|
||
|
|
<div class="section"> <p>The first configuration includes the following subsystems:</p>
|
||
|
|
<ul><li>QBASE, the controlling subsystem, supports interactive, batch, and communications
|
||
|
|
jobs.</li>
|
||
|
|
<li>QSPL supports processing of spooling readers and writers.</li>
|
||
|
|
<li>QSYSWRK supports various server functions such as TCP/IP.</li>
|
||
|
|
<li>QUSRWRK is the user work subsystem. It contains jobs that are started
|
||
|
|
by servers to do work on behalf of a user.</li>
|
||
|
|
</ul>
|
||
|
|
<p>QBASE automatically starts when the server is started. An automatically
|
||
|
|
started job in QBASE starts QSPL.</p>
|
||
|
|
<p>The second controlling subsystem configuration
|
||
|
|
supplied is more complex. This configuration includes the following subsystems:</p>
|
||
|
|
<ul><li>QCTL, the controlling subsystem, supports interactive jobs started at
|
||
|
|
the console.</li>
|
||
|
|
<li>QINTER supports interactive jobs started at other workstations.</li>
|
||
|
|
<li>QCMN supports communications jobs.</li>
|
||
|
|
<li>QBATCH supports batch jobs.</li>
|
||
|
|
<li>QSPL supports processing of spooling readers and writers.</li>
|
||
|
|
<li>QSYSWRK supports various server functions such as TCP/IP.</li>
|
||
|
|
<li>QUSRWRK is the user work subsystem. It contains jobs that are started
|
||
|
|
by servers to do work on behalf of a user.</li>
|
||
|
|
</ul>
|
||
|
|
<p>If you change your configuration to use the QCTL controlling subsystem,
|
||
|
|
it starts automatically when the system is started. An automatically started
|
||
|
|
job in QCTL starts the other subsystems.</p>
|
||
|
|
<p>You can change your subsystem
|
||
|
|
configuration from QBASE to QCTL by changing the system value QCTLSBSD (controlling
|
||
|
|
subsystem) to QCTL on the <span class="cmdname">Change System Value (CHGSYSVAL)</span> command
|
||
|
|
and starting the system again.</p>
|
||
|
|
<p>You can change the IBM-supplied subsystem
|
||
|
|
descriptions or any user-created subsystem descriptions by using the <span class="cmdname">Change
|
||
|
|
Subsystem Description (CHGSBSD)</span> command. You can use this command
|
||
|
|
to change the storage pool size, storage pool activity level, and the maximum
|
||
|
|
number of jobs for the subsystem description of an active subsystem.</p>
