<h1 class="topictitle1">CL command considerations for DDM</h1>
|
||
|
|
<div><p>Both compiled control language (CL) programs and interactively
|
||
|
|
entered CL commands can refer to DDM files.</p>
|
||
|
|
<div class="section"><p>Generally, DDM file names can be specified in CL commands anywhere
|
||
|
|
a database file name can be specified for both <span class="keyword">iSeries™</span> and
|
||
|
|
non-<span class="keyword">iSeries</span> target servers.
|
||
|
|
But there are some limitations.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>Listed here are some examples of where DDM file names
|
||
|
|
can be specified:</p>
|
||
|
|
<ul><li>DDM file names can be specified on many of the database file-related commands,
|
||
|
|
such as the copy, display, and override file commands.</li>
|
||
|
|
<li>DDM file names can be specified on the create file commands to access
|
||
|
|
remote <em>source</em> files, but only if the target server is an <span class="keyword">iSeries server</span> or
|
||
|
|
a <span class="keyword">System/38™</span>. A DDM file name
|
||
|
|
can be specified on the SRCFILE parameter, and a member name can be specified
|
||
|
|
on the SRCMBR parameter. If the remote source file referred to by the DDM
|
||
|
|
file is not on an <span class="keyword">iSeries server</span> or
|
||
|
|
a <span class="keyword">System/38</span>, an error occurs.
|
||
|
|
The considerations for remote <span class="keyword">iSeries</span> or <span class="keyword">System/38</span> source members are the same
|
||
|
|
as for local source members.</li>
|
||
|
|
<li>DDM file names can be specified on the FILE parameter of the <span class="cmdname">Declare
|
||
|
|
File (DCLF)</span> command.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>When a DDM file name is specified, some commands act on files
|
||
|
|
on the source server, some act on target files, and some parameter values
|
||
|
|
allow you to specify either a source or target file.</p>
