The Redwood Shores, California-based software vendor said it had tested and certified its Database 10g, Application Server 10g, Real Application Clusters, Collaboration Suite, and E-Business Suite 11i products with Novell’s SLES 9.

Released in August 2004, SLES 9 is based on version 2.6 of the Linux kernel, and includes improved support for SMP processor clustering, much-improved support for NUMA clustering, a new job scheduler, and a new technology called Class-based Kernel Resource Management, and improved I/O performance.

The certification of Oracle’s products on the operating system gives it a major boost for potential enterprise deployments ahead of rival Red Hat Inc’s introduction of full 2.6 kernel functionality in the forthcoming Red Hat Enterprise Linux 4.
