<h1 class="topictitle1">Access files with DDM</h1>
<div><p>These topics describe the types of files supported by an <span class="keyword">iSeries™ server</span>, when the DDM file and remote
file must exist, and how to specify the names of remote files. Also included
are examples and considerations for <span class="keyword">iSeries</span>-to-<span class="keyword">iSeries</span> and <span class="keyword">iSeries</span>-to-<span class="keyword">System/36™</span> file accessing.</p>
</div>
<div>
<ul class="ullinks">
<li class="ulchildlink"><strong><a href="rbae5typeoffile.htm">Types of files supported by i5/OS DDM</a></strong><br />
<span class="keyword">i5/OS™</span> DDM supports
all <span class="keyword">iSeries</span> file types when
the target server is another <span class="keyword">iSeries server</span>.</li>
<li class="ulchildlink"><strong><a href="rbae5existence.htm">Existence of DDM file and remote file</a></strong><br />
A file on a target server cannot be accessed for any type of operation (such as open, read, write, or display) unless a DDM file associated with the remote file already exists on the source server.</li>
<li class="ulchildlink"><strong><a href="rbae5namecon.htm">Rules for specifying target server file names for DDM</a></strong><br />
The rules for specifying the name of a DDM file (on the local <span class="keyword">iSeries server</span>) are the same as for any other
file type on an <span class="keyword">iSeries server</span>. The
rules, however, for specifying the name of a remote file depend on the type
of target server.</li>
<li class="ulchildlink"><strong><a href="rbae5exiseries.htm">Examples: Access iSeries DDM remote files (iSeries-to-iSeries)</a></strong><br />
The examples show how access to a DDM file becomes an indirect
reference (by using DDM) to the actual file on some other server. These examples
are <span class="keyword">iSeries</span>-to-<span class="keyword">iSeries</span> examples.</li>
<li class="ulchildlink"><strong><a href="rbae5ex36.htm">Example: Access System/36 DDM remote files (iSeries-to-System/36)</a></strong><br />
Of the command examples given in the previous topic (showing <span class="keyword">iSeries</span>-to-<span class="keyword">iSeries</span> examples),
all except the first example can be coded the same way for accessing a file
on a <span class="keyword">System/36</span>.</li>
