1.2 Obtaining and Installing the UEK Packages

You can obtain and install the UEK and associated firmware packages in the following ways:

  • If you have a valid Oracle Linux Support subscription, you can obtain the latest Oracle Linux and UEK packages from the Unbreakable Linux Network (ULN) at https://linux.oracle.com. After you have logged in to ULN and registered your system, you can subscribe the system to the UEK channel for the appropriate Oracle Linux release and machine architecture. This channel will provide the latest Oracle Linux packages and updates for your system as they become available.

    For more information about ULN, see Oracle Linux Unbreakable Linux Network User's Guide.

  • You can obtain Oracle Linux and UEK packages from the Oracle Linux Yum Server repository. To enable access, download the appropriate configuration file, such as https://yum.oracle.com/public-yum-ol6.repo to the /etc/yum.repos.d directory, and edit the file to enable the repositories from which you want to receive updates, such as ol6_x86_64_UEKR4 for the kernel packages that are specific to UEK R4. You can use the yum command to download and install the packages.

    For more information about yum, see Chapter 2, Yum

To list the installed kernel packages and also the kernel packages that are available to be installed from the repositories that you have enabled, use the following yum command:

# yum list kernel*
