Oracle has unveiled a pre-release distribution of Oracle Linux 9, based on the Red Hat Enterprise Linux 9 package base and fully binary compatible with it. For download without restrictions, an installation iso image is offered, 8 GB in size, prepared for x86_64 and ARM64 architectures (aarch64). For Oracle Linux 9, unlimited and free access to the yum repository with binary package updates with bug fixes (errata) and security issues is open. Separately maintained repositories with sets of Application Stream and CodeReady Builder packages are also prepared for download.
In addition to the RHEL kernel package (based on the 5.14 kernel), Oracle Linux offers its own Unbreakable Enterprise Kernel 7, based on the Linux 5.15 kernel and optimized for industrial software and Oracle hardware. The kernel sources, including the breakdown into individual patches, are available in the public Oracle Git repository. The Unbreakable Enterprise Kernel is installed by default, positioned as an alternative to the regular RHEL kernel package and provides a number of advanced features, such as DTrace integration and improved Btrfs support. Apart from the additional kernel, the Oracle Linux 9 and RHEL 9 releases are identical in functionality.
