Chapter 3 Shipped Kernels

Oracle Linux 7.9 for the x86_64 platform ships with the following kernel packages:

kernel-3.10.0-1160.el7

Red Hat Compatible Kernel (RHCK)

kernel-uek-5.4.17-2011.6.2.el7uek

Unbreakable Enterprise Kernel Release 6 (UEK R6)

UEK R6 is the default kernel in this release. Note that if you are upgrading from a previous release, you are automatically subscribed to the UEK R6 Unbreakable Linux Network (ULN) channel or yum repository. See Section 6.1, “General Upgrade Information” for more information.

Oracle Linux 7.9 is tested as a bundle, as shipped on the installation media image. When installed from the installation media image, the minimum kernel version that is supported is the kernel that is included in the image. Downgrading kernel packages is not supported, unless otherwise recommended by Oracle Support.

Previous UEK releases, such as UEK R5, can also be installed from the Oracle Linux yum server or ULN.

The kernel source code for the shipped kernel is available after the initial release through a public git source code repository at https://github.com/oracle/linux-uek.
