<h1 class="topictitle1">Source server actions dependent on type of target server</h1>
|
|
<div><p>If the target server is not another <span class="keyword">iSeries™ server</span> or <span class="keyword">System/38™</span>, only the DDM architecture
|
|
commands defined in Level 2.0 and earlier of the DDM architecture are used.</p>
|
|
<p>If the target is an <span class="keyword">iSeries server</span> or
|
|
a <span class="keyword">System/38</span>, then <span class="keyword">iSeries</span> server
|
|
and <span class="keyword">System/38</span> extensions to
|
|
the architecture are used to support some operations not defined by the Level
|
|
2.0 DDM architecture. Examples of <span class="keyword">System/38</span> and <span class="keyword">iSeries</span> extensions to the architecture
|
|
are the <span class="cmdname">Submit Remote Command (SBMRMTCMD)</span> and processing
|
|
file members of remote files.
|
|
For creating a file when the source is an <span class="keyword">iSeries server</span> and
|
|
the target is also an <span class="keyword">iSeries server</span>,
|
|
an <span class="keyword">iSeries</span> extension is used.</p>
|
|
<p>Target servers that are not <span class="keyword">iSeries</span> servers
|
|
or <span class="keyword">System/38</span>s might not be capable
|
|
of handling all of the functions that an <span class="keyword">iSeries server</span> or
|
|
a <span class="keyword">System/38</span> can handle. For
|
|
example, a <span class="keyword">System/36™</span> does not
|
|
support relative record processing and keyed record processing with one open
|
|
operation; therefore, programs that mix accessing records in a file by key
|
|
or relative record do not work if the file is on a <span class="keyword">System/36</span>.
|
|
In addition, target servers that do not support Level 2.0 of the DDM architecture
|
|
can only handle functions defined in the level they support.</p>
|
|
<p>Neither the <span class="keyword">System/36</span> nor
|
|
the <span class="keyword">System/38</span> support access
|
|
to folder management objects.</p>
|
|
<div class="note"><span class="notetitle">Note:</span> An <span class="keyword">iSeries server</span> only allows
|
|
access to folder management services (FMS) objects when the source supports
|
|
Level 2.0 of the DDM architecture for <dfn class="term">stream files</dfn> (files on
|
|
disks in which data is read and written in consecutive fields without record
|
|
boundaries) and directories, for example, the IBM<sup>®</sup> Personal Computer using DDM.</div>
|
|
<p>An <span class="keyword">iSeries server</span> as a source
|
|
server does not support access to stream files and directories.</p>
