Wim Coekaerts, senior vice-president of Linux and virtualisation engineering at Oracle, said, "With the combination of Oracle Linux and the Unbreakable Enterprise Kernel, customers gain fast access to optimisations, new enhancements, and bug fixes."
The Unbreakable Enterprise Kernel is the only Linux kernel Oracle recommends for use with Oracle software. However, the company said it would continue to support Red Hat's Compatible Kernel. Customers can choose to run the Red Hat Compatible Kernel if they prefer strict Red Hat compatibility over a system optimised to run Oracle and other enterprise software, Oracle said.
Unbreakable Linux is one of two operating systems supported on Oracle's Exalogic appliance.
