<div class="section"><p>For brevity, the term <em>DDM server</em> is used rather than <em>DRDA/DDM
|
||
|
|
server</em> in the following discussion. Sometimes, however, it might be referred
|
||
|
|
to as the <em>TCP/IP server</em>, the <em>DRDA server</em>, or the <em>server</em> when
|
||
|
|
the context makes the use of a qualifier unnecessary.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>The DDM server consists of two or more jobs, one of which is what
|
||
|
|
is called the DDM <em>listener</em>, because it listens for connection requests
|
||
|
|
and dispatches work to the other jobs. The other job or jobs, as initially
|
||
|
|
configured, are prestart jobs which service requests from the DRDA or DDM client
|
||
|
|
after the initial connection is made. The set of all associated jobs, the
|
||
|
|
listener and the server jobs, are collectively referred to as the <em>DDM server</em>.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>The term <em>client</em> is used interchangeably with <em>DRDA Application
|
||
|
|
Requester</em> (or AR) in the DRDA application environment. The term client will be
|
||
|
|
used interchangeably with <em>DDM source system</em> in the DDM (distributed
|
||
|
|
file management) application environment.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p><img src="./delta.gif" alt="Start of change" />The term <em>server</em> is used interchangeably
|
||
|
|
with <em>DRDA Application
|
||
|
|
Server</em> (or AS) in the DRDA application environment. The term server will be
|
||
|
|
used interchangeably with <em>DDM target system</em> in the DDM application
|
||
|
|
environment. (Note that in some contexts, the iSeries system (the hardware) is also
|
||
|
|
called a server, or the iSeries server.)<img src="./deltaend.gif" alt="End of change" /></p>
