Performance spielt für uns nicht nur bei IT-Anwendungen eine Rolle. Deshalb starten wir auch dieses Jahr wieder beim M-net Firmenlauf in Augsburg. Als Bezug zu Linux und Open-Source nehmen wir natürlich unseren "Tux" auf dem Laufshirts mit ;-)
OC4J JSP Profiling with JProbe
I have done some Profiling with JProbe - hey I didn't know that you can download a Freeware Edition from Quest.
To get it working with Oracle OC4J 10g (Version 10.1.3) I used the following configuration:
- Application Server Type: Other Server
- Server Directory: toplevel directory where you installed OC4J (<install -dir>)
- Server Class: oracle.oc4j.loader.boot.BootStrap
- Class Path: <install -dir>/j2ee/home/oc4j.jar
- Java Executable: /usr/java/j2sdk1.4.2_09/bin/java
- Java Options: -DORACLE_HOME=<install -dir>
- Working Directory: <install -dir>
- Server Class Arguments: -config <install -dir>/j2ee/home/config/server.xml
I hope that helps to get you started with profiling. It is always a cool thing to see where the performance bottlenecks are buried inside of some piece of software. Sometimes some "improvements" make it worse when seeking to make it better :-D.
