The J2EE Request Profiler is used to collect execution data from distributed applications, which may span multiple processes and hosts. This collected data can be viewed as sequence diagrams. If you start WebSphere Application Server in the profiling mode, the J2EE Request Profiler is enabled automatically. If you start WebSphere Application Server using the run or debug modes, then you will have to manually enable the J2EE Request profiler.

To enable the J2EE Request Profiler in run or debug mode for WebSphere Application Server v5.x:
This enables the Sequence Diagram run time, which is disabled by default. You can now specify that the J2EE Request Profiler is to be used to collect data from the application.
Note: Whenever you want to disable the J2EE Request Profiler, set the PD_DT_ENABLED variable to the value false.
Note: A J2EE Request Profiler sample is shipped with the product. For instructions on how to use it, refer to its readme (File > New > Example > J2EE Request Profiler > Next > Finish).
