|
|
<div><p>Data file utility (DFU) data entry applications can be created
|
|
and started with DDM to work with remote files in the same manner as with
|
|
local files. Most DFU functions are performed with the remote file as though
|
|
it were a local file.</p>
|
|
<div class="section"><p>When you create or change a DFU function of Application
|
|
Development Tools and the remote file is an <span class="keyword">iSeries™</span> or <span class="keyword">System/38™</span> logical file, the following
|
|
consideration applies: either DDM files referring to each remote based-on
|
|
file must exist on the source server, and the DDM file and library names must
|
|
match those of the remote based-on files; or, alternatively, physical files
|
|
with the same file and library names and the same record formats as the remote
|
|
based-on files must exist on the source server. Because only the record formats
|
|
are needed from the physical files, they need not contain data. Using this
|
|
alternative, if the record formats of the remote based-on files are changed,
|
|
the record formats on the source server must also be changed so that the record
|
|
formats match. Similar considerations apply when the remote file is a <span class="keyword">System/36™</span> logical file.</p>
|
|
</div>
|
|
<div class="section"><p>DFU supports <span class="keyword">iSeries server</span>, <span class="keyword">System/38</span>, and <span class="keyword">System/36</span> remote
|
|
files. However, DFU does not prevent you from using non-<span class="keyword">iSeries</span>,
|
|
non-<span class="keyword">System/38</span>, or non-<span class="keyword">System/36</span> remote files and you might
|
|
experience problems when using such files.</p>

|
</div>
|
|
<div class="section"><p>Non-<span class="keyword">iSeries</span> or <span class="keyword">System/36</span> files are program-described

files. DFU allows you to use either a local or remote file containing ILE
|
|
RPG file and input specifications to define these data files.</p>
