Oracle Linux 5.6 DVDs Now Available
By Sergio on Jan 26, 2011
On Thursday 20 January 2011, Oracle Linux 5.6 was released on the Unbreakable Linux Network for customers with an Oracle Linux support subscription. Today we published the installation DVD images on edelivery.oracle.com/linux. As always, Oracle Linux 5.6 is free to download, install and use. The release notes are here, but I wanted to highlight a few items about this release.
Unbreakable Enterprise Kernel
Oracle Linux 5.6 makes Unbreakable Enterprise Kernel the default kernel after installation unless you perform a custom installation. Note that Unbreakable Enterprise Kernel is available for the x86_64 platform only. Yesterday, Chris Mason, our Director of Linux Engineering delivered a webcast on the performance improvements we made to this kernel. I highly recommend you watch the replay.

The Unbreakable Enterprise Kernel is delivered via the package kernel-uek:
[root@localhost ~]# yum info kernel-uek Loaded plugins: rhnplugin, security Installed Packages Name : kernel-uek Arch : x86_64 Version : 2.6.32 Release : 100.26.2.el5 Size : 78 M Repo : installed Summary : The Linux kernel URL : http://www.kernel.org/ License : GPLv2 Description: The kernel package contains the Linux kernel (vmlinuz), the core of any : Linux operating system. The kernel handles the basic functions : of the operating system: memory allocation, process allocation, device : input and output, etc.Red Hat compatible kernel
Oracle Linux 5.6 also includes a Red Hat compatible kernel built directly from RHEL source. It's already installed, so booting it is a matter of editing /etc/grub.conf
[root@localhost ~]# rpm -qa | grep kernel-2.6.18 kernel-2.6.18-238.el5Red Hat compatible kernel with bug fixes by Oracle
Finally, Oracle Linux 5.6 includes the Red Hat compatible kernel with critical bug fixes from Oracle. You can review the patches here. This kernel can be install directly from the DVD or from ULN if you're an Oracle Linux support customer.Yum access to Unbreakable Linux Network (ULN)
