<h2>iSeries Subsystem Information</h2>
<p>A server program should run in the same subsystem that other server programs
are running. For controlling resource use, such as main storage, a separate
subsystem for running all server programs is usually best. This is also
advantageous for allowing performance tuning, such as the number of page
faults. Generally, iSeries<SUP>(TM)</SUP> applications run in subsystem QBASE.</p>
<p>If the subsystem under which you want the server program to run was created
with the system defaults, you will not have to add a work station entry to the
subsystem description. If you do need to add a work station entry to the
subsystem description, however, you can use the Add Work Station Entry (ADDWSE)
command.</p>
<p>Before a work station is allowed to sign-on, it must be defined to a
subsystem. In this case, the work station is the virtual terminal device
(QPADEVnnnn) automatically created by the i5/OS<SUP>(TM)</SUP> licensed program. The work
station name, work station type, or *ALL must be specified in the subsystem
description. Use the Display Subsystem Description (DSPSBSD) command to see the
list of work station entries defined for a subsystem. The following command can
be used to add all work station types to a subsystem named QBASE:</p>
<pre>
ADDWSE SBSD(QBASE) WRKSTNTYPE(*ALL)
</pre>
<p>For more information on automatically creating virtual terminals, see
<a href="vt1f.htm#QAUTOVRT">Setting the Number of Automatically Created
Virtual Terminals</a>.</p>
<p><strong>Note:</strong> The ADDWSE command is valid only when the subsystem
description is not active.</p>
