<div class="section"><h4 class="sectiontitle">What can I do with this system value?</h4><p>You may specify
|
|
the number of virtual devices to automatically configure.</p>
|
|
<p>If you do
|
|
not want to automatically configure any devices, do not select this option
|
|
(0). This option is equivalent to 0 in the character-based interface. Devices
|
|
are not automatically deleted to bring the total number down to the specified
|
|
limit for this system value. Therefore, if you change from a higher value
|
|
to a lower value, the system does not delete virtual devices.</p>
|
|
<p>Before
|
|
creating devices for Telnet sessions or for passthrough sessions for which
|
|
the client does not specify the name of the request, this system value will
|
|
be checked to make sure the new device does not exceed the number specified
|
|
for this system value. If creation of another virtual device description exceed
|
|
the limit specified by this system value, the device will not be created for
|
|
Telnet or passthrough. However, a request for a device for a passthrough session
|
|
will <span class="uicontrol">not</span> check the limit for this system value before
|
|
creating a device description if the client specified the name on the incoming
|
|
request (Start Up Record).</p>
|
|
<p>The system deletes virtual devices only if
|
|
they are damaged, or if the device needs to be created again to change its
|
|
type.</p>
|
|
<p>If you select <span class="uicontrol">Pass-through devices and Telnet</span> (1),
|
|
select one of the following options to specify the maximum number of devices
|
|
that are configured:</p>
|
|
<ul><li><span class="uicontrol">No maximum number of devices (*NOMAX)</span> <p>An unlimited
|
|
number of virtual devices may be configured automatically.</p>
|
|
</li>
|
|
<li><span class="uicontrol">Maximum number of devices (0-32500)</span> <p>The maximum
|
|
number of devices that may be configured automatically. Possible values are
|
|
0 through 32500 devices. A value of 0 indicates that automatic configuration
|
|
of virtual devices is off.</p>
|
|
</li>
|
|
<li><span class="uicontrol">Run registered exit program (*REGFAC)</span> <p>The program
|
|
registered for the Virtual Device Selection (QIBM_QPA_DEVSEL) exit point is
|
|
called when a virtual device needs to be selected or automatically created
|
|
by the system. If the program registered for the exit point does not exist
|
|
or if it returns with an error, the system will handle the situation as if
|
|
this system value is deselected (do not allow virtual devices to be automatically
|
|
configured).</p>
|
|
<p>If this value is selected, the program will be called every
|
|
time a virtual device is requested by a pass-through or Telnet session.</p>
