3.3 Upgrading the Unbreakable Enterprise Kernel

Oracle Linux 6 Update 5 ships with the latest Unbreakable Enterprise Kernel Release 2 for i386 and Unbreakable Enterprise Kernel Release 3 for x86-64. If you upgrade your system from the installation media, there are four upgrade scenarios:

yum uses whatever repositories you have configured on your system to upgrade it. You can find the latest UEK R2 packages in the ol6_i386_UEK_latest and ol6_x86_64_UEK_latest repositories and the latest UEK R3 packages in the ol6_UEKR3_latest repository.

If you want to install the latest UEK R2 kernel on an i386 or x86-64 system, subscribe your system to the ol6_i386_UEK_latest or ol6_x86_64_UEK_latest channel on ULN, or configure the repository in the /etc/yum.repos.d/public-yum-ol6.repo file as shown here:

If you want to update an x86-64 system to use the latest UEK R3 kernel, subscribe your system to the ol6_x86_64_UEKR3_latest channel on ULN, or configure the repositories in the /etc/yum.repos.d/public-yum-ol6.repo file as shown here:
