This answers some of your questions http://www.oracle.com/technetwork/articles/servers-storage-admin/uek-rel2-getting-started-1555632.html --- About the Unbreakable Enterprise Kernel for Oracle Linux Oracle Linux with the Unbreakable Enterprise Kernel is Oracle's fully supported, tested, and certified Linux operating system for the enterprise. Oracle Linux is free to download, use, and distribute, and it is optimized to run Oracle hardware, databases, and middleware. You can obtain ISO images of the installation media from the Oracle Software Delivery Cloud without charge (requires registration). The Oracle Linux base distribution is 100% userspace-compatible with Red Hat Enterprise Linux (RHEL). However, the Unbreakable Enterprise Kernel is released on an independent schedule and is always based on a recent version of the mainline Linux kernel. As a result, it delivers the latest innovations from mainline Linux, combined with tested performance and stability. It is installed and booted by default; major updates of the Unbreakable Enterprise Kernel are usually published every 12 to 18 months. --- However, I'd suggest that if you want to use Oracle' s kernel, you use Oracle' s Linux distro, which you can also download for free. Why come here and speak about mixing CentOS with Oracle kernel?. The answers will surely be mostly negative (like going to a Fedora mailing list and asking about using an Ubuntu kernel, or vice-versa). Do you expect the answers to be otherwise?. Seems like trolling to me. FC -- During times of Universal Deceit, telling the truth becomes a revolutionary act - George Orwell
