Oracle will be releasing in 2010 several new products for their WebLogic Suite. One of these will be JRockit VE (JRVE). JRVE will be a bare-metal install not requiring an underlying operating system.
Oracle believes they can coax significant performance gains for the JRockit JVM by removing the O/S barrier. Additional benefits include simplified administration, improved security and a single configuration file for setup.
For now JRVE is not expected to be a stand-alone product and will be used in support of the new Weblogic Suite Virtual Edition expected in 2010.
Some interesting specifications for JRVE versus a typical Linux implementation:
- 10 Commands
- 100 Parameters
- 1 Administrative Tool
- 1 second Boot Time
- 2MB (not GB) Memory Requirement
- No Shell support
With JRVE, the layers on the technology stack will shrink to just the JVM and the Application. This is distinctly less than many Java environments that require the O/S, JVM, App Server, SOA and then the Application on top of it.
