This session is about a new Oracle product line or initiative that provides another nice feature for Java platform.
Oracle VM which will be released during 2009 has the concept of light-weight VM (virtual machine). Since normal VM has to be installed on top of OS (Windows or Linux), the memory footprint as well as many other features become a big stumbling blocks for running applications.
So, Oracle introduced a concept of light weight VM concept. OS layers basically disappears. You can install JVM on top of Hypervisor directly by-passing OS layer.
JRocket VE comes with three flavors: JRocket Mission Control, JRocket Real Time, and JRocket JVM.
Hypervisor Optimized Java makes JRocket virtualization-aware and let JRocket and Hypervior work together. JRocket VE can handle networking, file storage, and memory management, but nothing else. Of course, JRocket VE can run any standard Java apps.
Once JRocket VE template is created, it's a matter of less than a minute that you can install and run the JRocket based WebLogic server with the application on the VM.
JRocket VE runs on single processor and memory can't be shared among VMs. Performance and security are key points for JRocket VE since it doesn't require underling OS layer.
There will be lots of changes and upgrades until we see the real product next year....
