The Unbreakable Enterprise Kernel Release 2 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 as well as the public yum repository. Four channels are available:
Oracle Linux 5 (x86):
ol5_i386_UEK_latestOracle Linux 5 (x86_64):
ol5_x86_64_UEK_latestOracle Linux 6 (x86):
ol6_i386_UEK_latestOracle Linux 6 (x86_64):
ol6_x86_64_UEK_latest
Existing Oracle Linux 5 or Oracle Linux 6 installations can be
upgraded to UEK R2 by enabling the appropriate
UEK_latest channel and running yum
update. The channel is automatically enabled for freshly
installed Oracle Linux 6 Update 3 systems that shipped with the
2.6.39-200 kernel version of UEK R2.
If you have questions regarding configuring or using yum to install updates, refer to Oracle® Linux 6: Administrator's Guide and to Oracle® Linux: Unbreakable Linux Network User's Guide for Oracle Linux 6 and Oracle Linux 7.
The kernel's source code is available via a public git source code repository at https://oss.oracle.com/git/?p=linux-uek-2.6.39.git.
