If your system is not registered with ULN, you can obtain most of the packages for Unbreakable Enterprise Kernel Release 3 (UEK R3) from Oracle Yum Server by subscribing it to additional repositories.
Before you begin:
Check that the system meets the requirements for installing UEK R3.
For details, see Chapter 3, Installation and Availability.
Remove some of the existing OpenFabrics Enterprise Distribution (OFED) packages.
You only need to do this if you have installed any OFED packages on your system and you want to replace them with the latest OFED tools packages. The packages have to be removed manually, see Section 3.4, “Upgrading OFED Packages on Oracle Linux 6 Systems”.
To Switch a System to UEK R3:
Log in as
root
on the system.Change directory to
/etc/yum.repos.d
.#
cd /etc/yum.repos.d
NoteThis assumes that yum on your system is configured to find repository files in the default
/etc/yum.repos.d
directory.Download the Oracle Linux 6 repository configuration file, https://yum.oracle.com/public-yum-ol6.repo.
For example:
#
wget https://yum.oracle.com/public-yum-ol6.repo
The
/etc/yum.repos.d
directory is updated with the repository configuration file.Enable the required repositories by editing the
public-yum-ol6.repo
file.You enable or disable repositories in the file by setting the value of the
enabled
directive to 1 or 0 as required.The kernel image and user-space packages are available on the following Oracle Yum Server repositories:

,libdtrace-*
, anduname26
packages.ol6_ofed_UEK
Latest OpenFabrics Enterprise Distribution (OFED) supporting tools for the Unbreakable Enterprise Kernel (UEK) on Oracle Linux 6 (x86_64).
As a minimum, you should enable the
ol6_latest
and theol6_UEKR3_latest
repositories.NoteThe DTrace and DRBD utility packages are not available on Oracle Yum Server.
Because you are switching to the latest UEK kernel, you can disable the previous UEK R2 (
ol6_UEK_latest
) repository.In the following example, the
ol6_UEKR3_latest
repository is enabled, and theol6_UEK_latest
repository is disabled:[ol6_UEKR3_latest] name=Latest Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch) baseurl=https://yum.oracle.com/repo/OracleLinux/OL6/UEKR3/latest/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=1 [ol6_UEK_latest] name=Latest Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch) baseurl=https://yum.oracle.com/repo/OracleLinux/OL6/UEK/latest/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=0
Upgrade all packages on the system, including kernel packages.
#
yum update
By default, the boot manager automatically enables the most recent kernel version so you do not need to change your GRUB configuration.
Reboot the system.
#
shutdown -r now
