Oracle Linux 6 Update 4 ships with the latest Unbreakable Enterprise Kernel Release 2. If you upgrade your system from the installation media, there are two upgrade scenarios:
If UEK R2 is not currently installed on the system, only the latest Red Hat Compatible Kernel is installed. The UEK R2 kernel is not installed.
If UEK R2 is currently installed on the system, the latest version of that kernel is installed.
yum uses whatever repositories you have
configured on your system to upgrade it. You can find the latest
UEK2 packages in the ol6_i386_UEK_latest and
ol6_x86_64_UEK_latest repositories. If you want
to install the latest UEK R2 kernel, subscribe your system to the
correct channel on ULN, or configure the repository in the
/etc/yum.repos.d/public-yum-ol6.repo file as
shown here:
