<div><p>The network design, hardware resources and traffic pressure often
|
||
|
|
have a significant effect on the performance of e-business applications. You
|
||
|
|
can use this topic for information on how to optimize network performance,
|
||
|
|
and tune server communication resources.</p>
|
||
|
|
<div class="section"><p>The network often plays a major role in the response time for
|
||
|
|
web applications. Moreover, the performance impact for network components
|
||
|
|
is often complex and difficult to measure because network traffic and the
|
||
|
|
available bandwidth may change frequently and are affected by influences the
|
||
|
|
system administrator may not have direct control over. However, there are
|
||
|
|
several resources available to help you monitor and tune the communication
|
||
|
|
resources on your server.</p>
|
||
|
|
<p>Refer to the following topics for more information:</p>
|
||
|
|
<dl><dt class="dlterm">Collection Services</dt>
|
||
|
|
<dd>Collection Services collects performance data for communication resources
|
||
|
|
at regular intervals. Of particular interest, the performance data files QAPMTCP
|
||
|
|
and QAPMTCPIFC store information about TCP servers. You can reference this
|
||
|
|
data by querying the files directly, or by using the reports included in the
|
||
|
|
Performance Tools licensed program.</dd>
|
||
|
|
<dt class="dlterm">System monitor</dt>
|
||
|
|
<dd>You can use the system monitors to provide information about how system
|
||
|
|
resources, including communications hardware, are being used on a server.
|
||
|
|
In particular, the line utilization and IOP metrics within the system monitor
|
||
|
|
can provide valuable data about network performance.</dd>
|
||
|
|
<dt class="dlterm">Track performance</dt>
|
||
|
|
<dd>Several applications and tools allow you to routinely collect performance
|
||
|
|
data for communication resources on the server and to monitor their performance
|
||
|
|
over time.</dd>

||
|
|
<dt class="dlterm"><span class="keyword">iSeries™</span> Performance Capabilities

|

|
|
<dd>The Performance Capabilities Reference provides detailed information,
|
||
|
|
reports and examples that can help you configure or tune your server for optimal
|
||
|
|
performance. In particular, see chapter 5: Communications Performance to help
|
||
|
|
you plan for and manage communication resources.</dd>
