<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> > <span class="uicontrol">Network</span> > <span class="uicontrol">Servers</span> > <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>
