Oracle Linux 6.10 ships with the latest Unbreakable Enterprise Kernel Release 2 for i386 and Unbreakable Enterprise Kernel Release 4 for x86-64.
If you upgrade your system from the installation media, the following five upgrade scenarios are possible:
If UEK R2 or UEK R4 is not currently installed on the system, only the latest Red Hat Compatible Kernel is installed. The UEK R2 or UEK R4 kernel is not installed.
If UEK R2 is currently installed on an i386 system, the latest version of the UEK R2 kernel is installed.
If UEK R2 is currently installed on an x86-64 system and you upgrade using the Oracle Linux 6.10 installation media for x86-64, which do not contain a UEK R2 repository, the latest version of UEK R2 is not installed.
If UEK R3 is currently installed on an x86-64 system, and you upgrade using the Oracle Linux 6.10 installation media for x86-64, which do not contain a UEK R3 repository, the latest version of UEK R3 is not installed, the system continues to boot into the existing UEK R3 release.
If UEK R4 is currently installed on an x86-64 system, the latest version of the UEK R4 kernel is installed.
The yum command uses whatever repositories
you have configured on your system to upgrade the system. You
can find the latest UEK R2 packages in the
ol6_i386_UEK_latest
and
ol6_x86_64_UEK_latest
repositories, the
latest UEK R3 packages in the
ol6_UEKR3_latest
repository, and the latest
UEK R4 packages in the ol6_UEKR4
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
enable the ol6_UEK_latest
repository. For

# yum-config-manager --enable ol6_UEK_latest
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
enable the ol6_UEKR3_latest
repository. For
example:

If you want to update an x86-64 system to use the latest UEK R4
kernel, subscribe your system to the
ol6_x86_64_UEKR4
