Platform Virtualization Technologies Supported by Java ES 5 Update 1

Platform virtualization is the ability to run multiple, unrelated guest operating systems in a contained environment on top of shared hardware. Due to the many benefits of platform virtualization, there are a spectrum of virtualization technologies and products available today.

Sun has tested and supports deployments of Java ES 5 and Java ES 5 Update 1 components running on Solaris 10 environments virtualized using the Logical Domains (LDoms) software, which was introduced in Solaris 10 11/06.

LDoms runs on UltraSPARC T1-based and T2-based servers. For information about LDoms, it capabilities, and its requirements, see the Logical Domains documentation collection (http://docs.sun.com/coll/ldom1.0).

If you deploy Java ES components in a supported operating system within a virtualized environment other than LDoms and you encounter a problem, you may be asked to demonstrate the problem in a non-virtualized environment before Sun can respond with service.

As with deployments in non-virtualized environments, you should allocate recommended resources (processor, memory, storage, and so on) to each virtual machine so as to ensure sufficient levels of application performance. See the component documentation for recommended and supported system requirements.
