Installation Guide for Linux Operating Systems
The Oracle Unbreakable Enterprise Kernel for Linux is a recommended kernel that can be installed on top of Oracle Linux 5.5 or later releases, or Red Hat Enterprise Linux 5.5, 6.0, and later releases. This new kernel is based on the 2.6.32 Linux Kernel and includes optimizations developed by Oracle to ensure stability and optimal performance. All patches added to the 2.6.32 mainline kernel are open source.
Oracle Unbreakable Enterprise Kernel for Linux has demonstrated its stability reliability, and performance improvements in demanding environments. It is the kernel used in Oracle's Exadata and Exalogic systems. Furthermore, the Oracle Unbreakable Enterprise Kernel for Linux is now used in all benchmarks on Linux that Oracle participates in, as well as in Oracle's Validated Configurations program.
Because the Oracle Unbreakable Enterprise Kernel for Linux installs directly on Oracle Linux 5.7 and 5.8 (by default), and on Red Hat Enterprise Linux 5.7 and 5.8, there is no need to upgrade to a new major release of the Linux operating system to gain the benefits and features of this new kernel. And after you have installed this new kernel, you still have the option of easily switching back to the Red Hat Enterprise Linux kernel, and then, switching back and forth between the two kernels.
Oracle highly recommends deploying the Oracle Unbreakable Enterprise Kernel for Linux in your Linux environment, especially if you are running Oracle software. Oracle Unbreakable Enterprise Kernel for Linux is optional, however, and Oracle Linux continues to include a Red Hat compatible kernel, which is compiled directly from Red Hat Enterprise Linux (RHEL) source code, for customers who require strict RHEL compatibility. Oracle also recommends this new kernel for customers running third-party software and third-party hardware.
