<h1 class="topictitle1">DDM files and SQL</h1>
|
|
<div><p>You can use <span class="keyword">iSeries™</span> distributed
|
|
data management (DDM) support to help you do some distributed relational database
|
|
tasks within a program that also uses SQL distributed relational database
|
|
support.</p>
|
|
<p>It might be faster, for example, for you to use DDM and the Copy File (CPYF)
|
|
command to get a large number of records rather than an SQL FETCH statement.
|
|
Also, DDM can be used to get external file descriptions of the remote system
|
|
data brought in during compilation for use with the distributed
|
|
relational database application. To do this, you need to use DDM as described
|
|
in <a href="rbal1setup.htm#rbal1setup">Initial setup</a>.</p>
|
|
<div class="p">The following example shows how you can add a relational database directory
|
|
entry and create a DDM file so that the same job can be used on the application
|
|
server (AS) and application requester (AR). <div class="note"><span class="notetitle">Note:</span> Either both connections
|
|
must be protected or both connections must be unprotected for the conversation
|
|
to be shared.</div>
|
|
</div>
|
|
<div class="note"><span class="notetitle">Note:</span> By using the code examples, you agree to the terms of the <a href="codedisclaimer.htm">Code license and disclaimer information</a>.</div>

<pre><strong>Relational Database Directory:</strong>
|
|
|
|
ADDRDBDIRE RDB(KC000) +
|
|
RMTLOCNAME(KC000)
|
|
TEXT('Kansas City regional database')</pre>
|
|
<pre><strong>DDM File:</strong>
|
|
|
|
CRTDDMF FILE(SPIFFY/UPDATE)
|
|
RMTFILE(SPIFFY/INVENTORY)
|
|
RMTLOCNAME(KC000)
|
|
TEXT('DDM file to update local orders')</pre>
|
|
<p>Here is a sample program that uses both the relational database directory
|
|
entry and the DDM file in the same job on the remote server:</p>
|
|
<pre>
|
|
CRTSQL<em>xxx</em> PGM(PARTS1) COMMIT(*CHG) RDB(KC000) RDBCNNMTH(*RUW)
|
|
|

|
|
CLOSE SPIFFY/UPDATE;
