PHP on Oracle Linux

I've had a long feud at work with business units who work with outside contractors who insist on writing web apps using the very latest version of PHP, Apache and MySQL. While I welcome the use of open source, state-of-the-art technology, the one thing these contractors often overlook is the need for stability and continuity in enterprise-grade applications. Even web applications. It's useless to use the latest greatest feature set in PHP or MySQL, if the organizations you're targeting are all running RHEL 4u8, 5u2 or even RHEL3! And many do. The Enterprise Distributions for Linux lag behind public version for up to 18 months!

Oracle VM for SPARC

Oracle VM Server for SPARC provides the flexibility to deploy multiple Oracle Solaris operating systems simultaneously on a single platform. Oracle VM Server also allows you to create up to 128 virtual servers on one system to take advantage of the massive thread scale offered by the CMT architecture."
