<h4 id="rzahjnetatt-pi">Change network attributes</h4>
|
||
|
|
<p>Network attributes describe the local system name, the default local location
|
||
|
|
name, the default control point name, the local network identifier, and the
|
||
|
|
network node type. If the machine is an end-node, the attributes also contain
|
||
|
|
the names of the network servers that are used by this iSeries™ system. Network
|
||
|
|
attributes also determine whether the system uses HPR, or whether you want
|
||
|
|
to use virtual controllers for APPN.</p>
|
||
|
|
<p><span class="bold">To change the network attributes, do the following</span>:</p>
|
||
|
|
<ol type="1">
|
||
|

<li>Vary off all APPC and host controllers. The easiest way to do this is
|
||
|
|
to use:
|
||
|

|
||

<div class="notebody">When using automatic

|
|
creation of controllers on LANs and you vary off the controllers, you have
|

approximately 2 minutes before the iSeries automatically varies on the controllers

|

again. If you have many configuration objects, temporarily turn off APPN auto-creation
|

on the LAN line by using the command CHGLINxxx AUTOCRTCTL(*NO), where xxx
|
||

is TRN, ETH, DDI, or WLS. When you have changed the necessary network attribute,

use the command CHGLINxxx AUTOCRTCTL(*YES) to resume normal APPN function.</div></li>

|
||
|
|
<p>On the iSeries, local applications that need to establish LU 6.2 sessions to
|
||
|
|
other locations in the APPN network require an APPC device description that
|
||
|
|
specifies APPN(*YES). For simplicity, these devices are referred to as APPN
|
||
|
|
devices. Multiple device descriptions can be created and used simultaneously
|
||
|
|
to communicate between the same local location and the remote location pair.
|
||
|
|
After a session is established, the controller description continues to use
|
||
|
|
the same APPN device description for the life of that session.</p>
|
||
|
|
<p><span class="bold">To configure virtual controllers, do the following:</span></p>
|
||
|
|
<ul>
|
||
|
|
<li>Set the ALWVRTAPPN network attribute to (*YES)</li></ul>
|
||
|
|
<p>After this is done, existing APPN device descriptions (attached to a real
|
||
|
|
controller description) will no longer be used.</p>

<p>To use Branch Extender, see the page <a href="rzahjrzahjbranchx.htm#rzahjbranchx">Configuring
|
||
|
|
Branch Extender support.</a></p>
|
||
|
|
<p>For more information about Branch Extender, see the page <a href="rzahjpernetdesinsts.htm#rzahjper-netdesinsts">Designing an APPN and HPR network to optimize communications performance</a>.</p>
|
||
|
|
<p><span class="bold">Considerations for system names</span></p>
|
||
|
|
<p>Use caution when you use names with the special characters # (X'7B'), $
|
||
|
|
('5B'), and @ ('7C'). These special characters might not be on the keyboard
|
||
|
|
of the remote system. These special characters are not supported for APPC
|
||
|
|
over TCP/IP (network IDs and location names only). The use of these symbols
|
||
|
|
should be limited to migration of the operating system. Do not use these characters
|
||
|
|
for newly created names.</p>
|
||
|
|
<p>If you are using a national language keyboard that does not have the #,
|
||
|
|
$, or @ symbols, see the appendix on national language keyboard types and
|
||
|
|
the appendix on code pages in the <a href="../nls/rbagsnatlangkeybrdtype.htm"> national language
|
||
|
|
keyboard types</a> topic in the Information Center.</p>
|
||
|
|
<p>The names that may be exchanged with remote systems include the following:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Network IDs</li>
|
||
|
|
<li>Location names</li>
|
||
|
|
<li>Mode names</li>
|
||
|
|
<li>Class-of-service names</li>
|
||
|
|
<li>Control-point names</li>
|
||
|
|
<li>Connection network names</li></ul>
