Announcing the release of Oracle Linux 8 Update 3

Simon Coter
Senior Manager, Oracle Linux and Virtualization Product Management

Oracle is pleased to announce the availability of the Oracle Linux 8 Update 3 for the 64-bit Intel and AMD (x86_64) and 64-bit Arm (aarch64) platforms.  Oracle Linux brings the latest open source innovations and business-critical performance and security optimizations for cloud and on-premises deployment. Oracle Linux maintains user space compatibility with Red Hat Enterprise Linux (RHEL), which is independent of the kernel version that underlies the operating system. Existing applications in user space will continue to run unmodified on Oracle Linux 8 Update 3 with Unbreakable Enterprise Kernel Release 6 (UEK R6) and no re-certifications are needed for applications already certified with Red Hat Enterprise Linux 8 or Oracle Linux 8.

Oracle Linux 8 Update 3 includes the UEK R6 on the installation image, along with the Red Hat Compatible Kernel (RHCK). For new installations, UEK R6 is enabled and installed by default and is the default kernel on first boot. UEK R6, the kernel developed, built, and tested by Oracle and based on the mainline Linux Kernel 5.4, delivers more innovation than other commercial Linux kernels.

  • Graphical Installer
