In yet another exciting Oracle OpenWorld announcement, attendees in San Franciso last month witnessed the debut of Oracle’s Unbreakable Enterprise Kernel for Oracle Linux.

The Unbreakable Enterprise Kernel is now available.

Optimised for Oracle software and hardware, it is described by Oracle as ‘fast, modern and reliable’ and reportedly delivers 75 percent better performance over a Red Hat Linux 5 compatible kernel.

Based on the 2.6.32 mainline Linux kernel, the Unbreakable Enterprise Kernel provides the core of Oracle’s Exadata Database Machine and the new Oracle Exalogic Elastic Cloud. It is now the only Linux kernel that Oracle recommends for use with Oracle software.

Oracle highlight the following features of the Unbreakable Enterprise Kernel for Oracle Linux:

  • It is fast, with the aforementioned 75 percent performance gain over Red Hat compatible kernel, a 200 percent increase in speed on infiniband messaging and 137 percent faster solid state disk access.
  • It is modern, with optimizations provided for large Non-Uniform Memory Access servers, improved energy efficiency, memory resource control and fine grained CPU.
  • It is specifically optimised for Oracle, with a capacity to run Oracle hardware, databases and middleware with excellent Linux performance and reliability.
  • It is reliable, with support for the Data Integrity Extensions and T10 Protection Information Model to stop corrupt data being written to storage, hardware fault management for greater application uptime and low overhead performance counters for tracing.

Oracle believe that Oracle Linux 5 and Red Hat Enterprise Linux 5 customers will find it easy to upgrade to the Unbreakable Enterprise Kernel, without the need to reinstall the operating system.
