JVM Internals

Good morning !

I have posted a new training material about Java Virtual Machine Internals + a real example of using DTrace to debug a sample application delivered with BEA Weblogic Portal 10. You can find the material and source code under this address.

Why JVM Internals ?

As SysAdmin you have to handle and maintain dozens of services running on top of an
application server: BEA, Sun, IBM, Oracle, etc ... but most often you
find yourself in troubles understanding concepts like: garbage collection,
generations, heap size, object allocation. The presentation will help you to understand
why is important to size a JVM and how to do that, to troubleshoot
a JVM problem on Solaris or simple debug a Java application using DTrace.
A real case example has been used, more will come later on.

If you're interested to have a class about this topic let me know. (Scandinavia only)
