<h1 class="topictitle1">Remote data areas</h1>
|
||
|
|
<div><p>A remote data area is a data area on a remote server.</p>
|
||
|
|
<p>You can access remote data areas by using Distributed Data Management (DDM).
|
||
|
|
You do not need to change or recompile an application program that resides
|
||
|
|
on one server when it retrieves data that resides on a remote server. To ensure
|
||
|
|
that you are accessing the correct data area, you may need to do one of the
|
||
|
|
following: </p>
|
||
|
|
<ul><li>Delete the standard data area and create a DDM data area that has the
|
||
|
|
same name as the original standard data area</li>
|
||
|
|
<li>Rename the standard data area</li>
|
||
|
|
</ul>
|
||
|
|
<p>You can create a DDM data area by doing the following: </p>
|
||
|
|
<pre> CRTDTAARA DTAARA(LOCALLIB/DDMDTAARA) TYPE(*DDM)
|
||
|
|
RMTDTAARA(REMOTELIB/RMTDTAARA) RMTLOCNAME(SYSTEMB)
|
||
|
|
TEXT('DDM data area to access data area on SYSTEMB')</pre>
|
||
|
|
<p>To use a value from a data area on a remote server in a CL program, use
|
||
|
|
the <span class="cmdname">Retrieve Data Area (RTVDTAARA)</span> command. Specify the
|
||
|
|
name of a DDM data area to bring the current value into a variable in your
|
||
|
|
program. If you change this value in your CL program and want to return the
|
||
|
|
new value to the remote data area, use the <span class="cmdname">Change Data Area (CHGDTAARA)</span> command
|
||
|
|
and specify the same DDM data area.</p>
|
||
|
|
<p>If you specify the name of a DDM data area when using the <span class="cmdname">Display
|
||
|
|
Data Area (DSPDTAARA)</span> command, the value of the DDM data area is
|
||
|
|
displayed, rather than the value of the remote data area. You can delete
|
||
|
|
a DDM data area using the <span class="cmdname">Delete Data Area (DLTDTAARA)</span> command.</p>
