Oracle Linux (abbreviated OL, formerly known as Oracle Enterprise Linux or OEL) is a Linux distribution packaged and freely distributed by Oracle, available partially under the GNU General Public License since late 2006.[5] It is, in part, compiled from Red Hat Enterprise Linux (RHEL) source code, replacing Red Hat branding with Oracle's. It is also used by Oracle Cloud and Oracle Engineered Systems such as Oracle Exadata and others.
Potential users can freely download Oracle Linux through Oracle's server, or from a variety of mirror sites, and can deploy and distribute it without cost.[6] The company's Oracle Linux Support program aims to provide commercial technical support, covering Oracle Linux and existing RHEL or CentOS installations but without any certification from the former (i.e. without re-installation or re-boot).
Oracle Corporation distributes Oracle Linux with two Linux kernels options.
Red Hat Compatible Kernel (RHCK) – identical to the kernel shipped in RHEL
Unbreakable Enterprise Kernel (UEK[8]) – based on newer mainline Linux kernel versions, with Oracle's own enhancements for OLTP, InfiniBand, SSD disk access, NUMA-optimizations, Reliable Datagram Sockets (RDS), async I/O, OCFS2, Btrfs and networking.[9][failed verification][10][failed verification][11]
Oracle Linux is application binary compatible with RHEL. Oracle claims that existing applications run unchanged because all application interfaces are identical to RHEL.
In August 2023, CIQ, Oracle, and SUSE founded Open Enterprise Linux Association (OpenELA) to collaborate on Enterprise Linux as an open source project to provide open and free Enterprise Linux source code. In November 2023, OpenELA publicly released Enterprise Linux source code and achieved important technical and governance milestones.
