Enable the trace service

Use the administrative console to enable the trace service for an application server. The trace service can be enabled dynamically or statically for an application server.

When you enable trace dynamically for a running application server, 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.

When you enable trace statically for an application server, 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.

Note: 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.
