<div><p>Quality of service (QoS) provides several methods to troubleshoot
|
||
|
|
QoS problems.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Communications trace</h4><p>Your server provides a communication
|
||
|
|
trace to collect data on a communication line, such as a local area network
|
||
|
|
(LAN) or wide area network (WAN) interface. The average user might not understand
|
||
|
|
the entire contents of the trace data. However, you can use the trace entries
|
||
|
|
to determine whether a data exchange between two points actually took place.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Enable QoS on the server</h4><p>If the QoS server does
|
||
|
|
not start, the first thing to check is whether QoS is enabled
|
||
|
|
on the server. When you configure your policies for the first time, the Initial
|
||
|
|
Configuration wizard automatically enables QoS on the server. However, if
|
||
|
|
this value has been changed for any reason, the server will not start.</p>
|
||
|
|
<p>To
|
||
|
|
verify that QoS is enabled on the server, follow these steps:</p>
|
||
|
|
<ol><li>In iSeries™ Navigator,
|
||
|
|
expand your server<span class="menucascade"><span class="uicontrol"></span> > <span class="uicontrol">Network</span> > <span class="uicontrol">IP Policies</span></span>.</li>
|
||
|
|
<li>Right-click <span class="uicontrol">Quality of service</span> and select <span class="uicontrol">Configuration</span>.</li>
|
||
|
|
<li>When the QoS interface appears, right-click <span class="uicontrol">QoS</span> and
|
||
|
|
select <span class="uicontrol">Properties</span>.</li>
|
||
|
|
<li>On the QoS properties page, verify that <span class="uicontrol">Enable QoS</span> is
|
||
|
|
selected.</li>
|
||
|
|
</ol>

<li class="ulchildlink"><strong><a href="rzak8journal.htm">Journal QoS policies</a></strong><br />
|
||
|
|
Quality of service (QoS) includes a journaling function. Journaling allows you to track QoS policy actions, such as when a policy was added, removed, or changed.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzak8logging.htm">Log QoS server jobs</a></strong><br />
|
||
|
|
When you encounter problems with your quality of service (QoS)
|
||
|
|
policies, analyze the iSeries server job logs. The job log contains error
|
||
|
|
messages and other information related to QoS.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzak8monitor_server.htm">Monitor server transactions</a></strong><br />
|
||
|
|
With the quality of service (QoS) monitor, you can verify that the QoS policies are working as you intend them to work.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzak8trace_tcp.htm">Trace TCP applications</a></strong><br />
|
||
|

You can use the quality of service (QoS) trace to work with trace functions and to view the current trace buffer.</li>
