<h1 class="topictitle1">Set the session keep-alive parameter</h1>
<div><p>You can set the maximum idle time that the TCP protocol will allow
before sending a probe to test for an inactive session using the TCP keep-alive
parameter.</p>
<div class="section"><p>The protocol will send keep-alive requests to the remote client
any time the session remains idle for periods longer than the the keep-alive
value. The idle period is defined by the Session keep alive timeout parameter
in Telnet properties in iSeries™ Navigator or a parameter in the CHGTELNA
command. When a session is deemed to be inactive (no response from the remote
client to any keep-alive probe), that session is ended; the virtual device
associated with the session is returned to the free pool of virtual devices;
and the iSeries operating
system performs the action set in the QDEVRCYACN system value on the interactive
job running on the virtual device. This action affects (only) named virtual
devices. For automatically selected virtual devices (QPADEVxxxx), the interactive
job always ends.</p>
<p>The Telnet server defines the keep-alive setting to
600 seconds by default.</p>
<p>The setting takes effect at server startup.
In addition to the session keep-alive timeout parameter, you might also want
to review the Time out interval settings in the Inactive Jobs System Values
in iSeries Navigator.
This timeout parameter is used to limit the amount of time that any interactive
job is allowed to be idle before the iSeries operating system performs the
action set in the QINACTMSGQ system value on the interactive job. In the case
of Telnet connected interactive jobs, an action of *DSCJOB is only honored
for named virtual devices. For automatically selected virtual devices (QPADEVxxxx),
an action of *DSCJOB will cause the interactive job to be ended.</p>
<p>To
set the keep-alive parameter for Telnet in iSeries Navigator, follow these steps:</p>
</div>
<ol><li><span>In iSeries Navigator,
select <span class="menucascade"><span class="uicontrol">your iSeries server</span> &gt; <span class="uicontrol">Network</span> &gt; <span class="uicontrol">Servers</span> &gt; <span class="uicontrol">TCP/IP</span></span>.</span></li>
<li><span>In the right pane, right-click <span class="uicontrol">Telnet</span> and
select <span class="uicontrol">Properties</span>.</span></li>
<li><span>On the <span class="uicontrol">Telnet Properties</span> page, click the <span class="uicontrol">Time-Out</span> tab.</span></li>
<li><span>On the <span class="uicontrol">Telnet Properties - Time-Out</span> page,
specify the action to take when jobs reach a time-out. You can also specify
how long to give an operation before the job times out. You can specify information
for both inactive jobs and disconnected jobs.</span></li>
