Oracle Linux images available on Oracle Cloud Infrastructure are frequently updated to help ensure access to the latest software. The latest Oracle Linux images provided in Oracle Cloud Infrastructure now include Oracle Linux 7 Update 5 with the Unbreakable Enterprise Kernel Release 5 (UEK R5). UEK R5 is an extensively tested and optimized Linux kernel designed for 64-bit (Intel x86_64) and ARM (aarch64) architectures and based on mainline version 4.14 LTS.

UEK R5 provides secure boot and performance optimization improvements, security and bug fixes, and driver updates. For details about UEK R5 improvements and more, visit these links:

You can take advantage of the new UEK R5 enhancements by deploying the latest Oracle Linux images on Oracle Cloud Infrastructure. Simply create an instance with the latest Oracle Linux 7.5 image provided on the Oracle Cloud Infrastructure Console, as shown in the following example:


To upgrade your existing Oracle Linux instances to UEK R5 on Oracle Cloud Infrastructure, enable access to the ol7_UEKR5 channel on your Oracle Cloud Infrastructure region’s mirrored Oracle Linux yum server repository or the ol7_x86_64_UEKR5 channel on the Unbreakable Linux Network (ULN), and run the yum update command. After the upgrade, you will need to reboot and select the UEK5 kernel (version 4.14.35) if it is not the default boot kernel.

And don’t forget, the UEK R5 update is included with Oracle Linux Premier Support at no additional cost with your Oracle Cloud Infrastructure subscription. This includes access to the latest packages and updates, 24x7 expert support, the My Oracle Support portal with an extensive Linux knowledge base, Oracle Ksplice zero-downtime updates, and the use of Oracle Enterprise Manager to manage and monitor Oracle Linux instances.
