<h3><a name="trbenabletrace"></a>Enable the trace service</h3>
|
||
|
|
<p>Use the WebSphere administrative console to enable the trace service for an
|
||
|
|
application server. The trace service can be enabled dynamically or statically
|
||
|
|
for an application server.</p>
|
||
|
|
<p>When you enable trace dynamically, the trace settings are in effect only for
|
||
|
|
the lifetime of the server. The trace settings are not saved to the application
|
||
|
|
server configuration. Use dynamic trace when the problem you are diagnosing
|
||
|
|
occurs after the application server has started successfully.</p>
|
||
|
|
<p>When you enable trace statically, the trace settings are not enabled until
|
||
|
|
the application server is started (or restarted). The trace settings are used
|
||
|
|
every time you start the application server. Use static trace when the problem
|
||
|
|
you are diagnosing occurs during application server startup.</p>
|
||
|
|
<p><strong>Note</strong>: Depending on the amount of trace event data being collected,
|
||
|
|
the trace service can negatively affect performance of the application server.
|
||
|
|
Once you have gathered the appropriate trace, be sure to disable the trace
|
||
|
|
service.</p>
|
||
|
