Chapter 3 Installation and Availability

The Unbreakable Enterprise Kernel Release 2 Quarterly Update 5 can be installed on Oracle Linux 5 Update 8 or newer, as well as Oracle Linux 6 Update 2 or newer, both running either the Red Hat compatible kernel or a previous version of the Unbreakable Enterprise Kernel. If you are still running an older version of Oracle Linux, first update your system to the latest available update release.

The kernel images are available as binary RPM packages from dedicated channels on Oracle's Unbreakable Linux Network (ULN) as well as the Oracle Public Yum repository. Four channels are available:

If your system is registered with ULN, make sure you subscribe it to the appropriate UEK_latest channel.

For Oracle Public Yum, the appropriate UEK_latest channel is automatically enabled in the yum respiratory file under /etc/yum.repos.d when you install Oracle Linux 5 update 9 or later and Oracle Linux 6 update 3 or later.

To upgrade an existing Oracle Linux 5 or Oracle Linux 6 installation to the latest UEK R2, enable the appropriate UEK_latest channel and run yum update.
