<div><p>This second example shows how multiple locations in a customer's
business can process the same order entry application using DDM.</p>
<div class="section"><p>The first task in this example shows how to use
DDM to put copies of the same application program on remote servers with one
primary file at a central location. The second task in this example shows
how to use DDM to copy a file to a remote server.</p>

At the central site of Philadelphia, the four files shown in the figure are being used by the ORDERENT application program.</li>
<li class="ulchildlink"><strong><a href="rbae5apaex2b.htm">DDM example 2: Description of ORDERENT program</a></strong><br />
Initially, the ORDERENT program exists only in library PGMLIB on the central server (in Philadelphia).</li>
<li class="ulchildlink"><strong><a href="rbae5apaex2c.htm">DDM example 2: Remote server ORDERENT files</a></strong><br />
The ORDERENT program remains the same at all locations, but the
CUSTMST2 file is now a <em>copy</em> of the central server's customer primary
file CUSTMAST.</li>
<li class="ulchildlink"><strong><a href="rbae5tsk1.htm">DDM example 2: Transfer a program to a target server</a></strong><br />
In this task, the central server in the DDM network, located in
Philadelphia, sends a program named ORDERENT to a remote <span class="keyword">System/38™</span> in
Chicago.</li>
<li class="ulchildlink"><strong><a href="rbae5apaex2e.htm">DDM example 2: Copy a file</a></strong><br />
After performing the first task in Example 2, you decide you want to copy the current level of the CUSTMAST file (in Philadelphia) to the server in Chicago so you can bring the CUSTMST2 file up to date.</li>
