About this task
This information applies to the following WebSphere® Application Server stand-alone
clients:
- Thin Client for JMS with WebSphere Application Server
- Thin Client for EJB with WebSphere Application Server
- Thin Client for JAX-WS with WebSphere Application Server
- Thin Client for JAX-RPC with WebSphere Application Server
Procedure
- To enable trace, use either a long form or short form system
property.
Note: Trace settings are determined from the
system property values the first time that a WebSphere Application Server client is called.
The trace settings are then fixed. Therefore, any subsequent changes
to the system property settings do not change the trace settings that
the WebSphere Application Server client
uses.
- To enable First Failure Data Capture (FFDC), use either
a long or short form system property.
Note: FFDC settings
are determined from the system property values the first time that
a WebSphere Application Server client performs
an FFDC. The FFDC settings are then fixed. Therefore, any subsequent
changes to the system property settings do not change the FFDC settings
that the WebSphere Application Server client
uses.
