<h1 class="topictitle1">The LANCNNTMR and LANCNNRTY parameters</h1>
|
||
|
|
<div><p>Your Systems Network Architecture (SNA) controller description
|
||
|
|
has two parameters: LAN connection timer (LANCNNTMR) and LAN connection retry
|
||
|
|
(LANCNNRTY). They work together to define the frequency and persistence of
|
||
|
|
polling the remote station to establish a connection.</p>
|
||
|
|
<p>LANCNNTMR specifies how long to wait before polling again.
|
||
|
|
LANCNNRTY specifies how many times to poll. If the system receives no response
|
||
|
|
from the remote station after polling the number of times specified in the
|
||
|
|
LANCNNRTY parameter, the following occurs:</p>
|
||
|
|
<ul><li>The user is notified that contact with the station was unsuccessful.</li>
|
||
|
|
<li>The system places the controller description in answer mode.</li>
|
||
|
|
<li>If the remote station signals your system to try your connection inquiry
|
||
|
|
again, your system attempts to establish connection again.</li>
|
||
|
|
</ul>
|
||
|
|
<p><strong>Performance problems:</strong></p>
|
||
|
|
<p>The default values of the parameters are designed for a single LAN and
|
||
|
|
might cause a connection failure when you access a remote station through
|
||
|
|
a remote bridge. The bridge might slow data traffic enough that the connection
|
||
|
|
timer expires before the remote station's response reaches you. If this is
|
||
|
|
the case, you should increase the values of LANCNNTMR and LANCNNRTY.</p>
|
||
|
|
<p>To change these parameters, see <a href="rzajychangingtimingparameters.htm#changing_timing_parameters">Change timing parameters</a>.</p>
