in which distributed relational database applications run.</p>
|

|
|
<p>Before using this information, you should be familiar with general programming

Distributed relational database support on the <span class="keyword">iSeries server</span> consists
|
||
|
|
of an implementation of IBM<sup>®</sup> Distributed Relational
|
||
|
|
Database Architecture™ (DRDA<sup>®</sup>) and integration of other SQL clients by use of
|
||
|
|
Application Requester Driver (ARD) programs.</li>

|
|
<li class="ulchildlink"><strong><a href="rbal1plan.htm">Planning and design</a></strong><br />
|
||
|
|
The first requirement for the successful operation of a distributed relational database is thorough planning. You must consider the needs and goals of your enterprise when making the decision to use a distributed relational database.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rbal1setup.htm">Initial setup</a></strong><br />
|
||
|
|
The runtime support for an <span class="keyword">iSeries</span> distributed
|
||
|
|
relational database is provided by the operating system. Therefore, when the
|
||
|
|
operating system is installed, distributed relational database support is
|
||
|
|
installed.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rbal1secure.htm">Security</a></strong><br />
|
||
|
|
The <span class="keyword">iSeries server</span> has
|
||
|
|
security elements built into the operating system to limit access to the data
|
||
|
|
resources of an application server. Security options range from simple physical
|
||
|
|
security to full password security coupled with authorization to commands
|
||
|
|
and data objects.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rbal1program.htm">Application development</a></strong><br />
|
||
|
|
Programmers can write high-level language programs that use SQL
|
||
|
|
statements for <span class="keyword">iSeries</span> distributed
|
||
|
|
application programs.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rbal1admin.htm">Administration</a></strong><br />
|
||
|
|
As an administrator for a distributed relational database, you are responsible for work being done on several servers.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rbal1recover.htm">Data availability and protection</a></strong><br />
|
||
|
|
In a distributed relational database environment, data availability not only involves protecting data on an individual server in the network, but also ensuring that users have access to the data across the network.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rbal1perform.htm">Performance</a></strong><br />
|
||
|
|
No matter what kind of application programs you are running on a server, performance can always be a concern. For a distributed relational database, network, server, and application performance are all crucial.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rbal1problem.htm">Troubleshooting</a></strong><br />
|
||
|
|
When a problem occurs accessing a distributed relational database, it is the job of the administrator to determine the nature of the problem and whether it is a problem with the application or a problem with the local or remote system.</li>

<li class="ulchildlink"><strong><a href="rbal1progxmp.htm">Examples: Application programming</a></strong><br />
