Easily Tuning Your Real-Time Application
TS-4807
Presenter: Bertrand Delsart, Sun Microsystems, Inc.; Frederic Parain, Sun Microsystems, Inc.
The usual Java technology-based tools are of limited use for profiling and understanding real-time applications. First of all, real-time applications are very sensitive to monitoring interference. In addition, the Real-Time Specification for Java (RTSJ) defines new paradigms, such as ImmortalMemory and NoHeapRealtimeThreads, that are not supported by the existing profiling APIs. Even more importantly, new tools must be developed to help users interpret the new determinism-related information and to configure the new tunable mechanisms that have been added to the various JMV machines to offer soft or hard real time.
This session covers how Sun's NetBeans IDE module addresses these issues for the Sun Java Real-Time System. A demo will help you understand how to easily perform, for instance, the following actions:
- Select some key configuration parameters
- Enable the system to learn how your application behaves and to tune the configuration accordingly
- Visualize the execution of your threads with very little interference, focusing on what matters
- Profile memory consumption
