<div><p>Problem analysis needs to be managed in a distributed database
|
|
environment. Problem analysis involves both identifying and resolving problems
|
|
for applications that are processed across a network of servers.</p>
|
|
<div class="section"><p>Consider the following items:</p>
|
|
<ul><li>Distributed database processing problems manifest themselves in various
|
|
ways. For example, an error return code might be passed to a distributed database
|
|
application by the server that detects the problem. In addition, responses
|
|
might be slow, wrong, or nonexistent.</li>
|
|
<li>Tools are available to diagnose distributed database processing problems.
|
|
For example, each distributed relational database product provides trace functions
|
|
that can help diagnose distributed data processing problems.</li>
|
|
<li>When server failures are detected by an <span class="keyword">iSeries™ server</span>,
|
|
the server logs information about program status immediately after the failure
|
|
is detected.</li>

</ul>
