<h4 id="rzahjvary-on">Automatic creation and vary on of the controller description</h4>
|
||
|
|
<p>When APPN support determines that it needs a controller description automatically
|
||
|
|
varied on, it determines if there are any existing controller descriptions
|
||
|
|
that follow the naming convention for automatically created APPC controllers.</p>
|
||
|
|
<p>Naming convention for controller descriptions:</p>
|
||
|
|
<ul>
|
||
|
|
<li>The first controller description created has the same name as the CP name
|
||
|
|
of the adjacent system</li>
|
||
|
|
<li>Additional controller descriptions created use the following conventions:</li></ul>
|
||
|
|
<dl>
|
||
|
|
<dt class="bold">CPNAMExx</dt>
|
||
|
|
<dd>Where CPNAME is the adjacent system's control-point name and xx is some
|
||
|
|
value from 00-FF.
|
||
|
|
</dd>
|
||
|
|
</dl>
|
||
|
|
<p>If the adjacent system does not send a control-point name, then the local
|
||
|
|
system creates a name that is based on the adjacent system's EXCHID value.
|
||
|
|
The format of the name is: </p>
|
||
|
|
<dl>
|
||
|
|
<dt class="bold">CIIIIIxx</dt>
|
||
|
|
<dd>Where C is a constant value, IIIII is the exchange identifier (that
|
||
|
|
is not including the three-digit block number), and xx is some value from
|
||
|
|
'00-FF'.
|
||
|
|
</dd>
|
||
|
|
</dl>
|
||
|
|
<p>For an existing controller description to be considered a possible candidate
|
||
|
|
for being automatically varied on, it must: </p>
|
||
|
|
<ul>
|
||
|
|
<li>Satisfy the naming convention</li>
|
||
|
|
<li>Be an APPC controller description</li>
|
||
|
|
<li>Be in a varied off status</li>
|
||
|
|
<li>Have RMTCPNAME and RMTNETID parameters that match the incoming XID parameter</li>
|
||
|
|
<li>Have LINKTYPE parameter specified as *LAN.</li></ul><p class="indatacontent"> If no controllers are found that meet these initial requirements for
|
||
|
|
automatic vary on, then the system creates a new controller. The name of this
|
||
|
|
controller will be the first available name that follows the naming convention
|
||
|
|
for this remote control-point name, and the controller description will indicate
|
||
|
|
that the controller owner is the system (CTLOWN(*SYS)).</p>
