Oracle Linux (OL, formerly known as Oracle Enterprise Linux) is a Linux distribution packaged and freely distributed by Oracle, available partially under the GNU General Public License since late 2006. It is 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 E-delivery service (Oracle Software Delivery Cloud) or from a variety of mirror sites, and can deploy and distribute it without cost.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). via_Wiki
Oracle Linux 7.6 release.
- Unbreakable Enterprise Kernel (UEK) Release 5 (4.14.35-1818.3.3) for x86-64 and Arm
- Red Hat Compatible Kernel (3.10.0-957) for x86-64 only
Notable new features in this release
- Pacemaker now supports path, mount, and timer systemd unit files. Although previous releases of Pacemaker supported service and socket systemd unit files, alternative units would fail. Pacemaker can now manage path, mount and timer systemd units.
- Package installation and upgrade using rpm can be tracked using audit events. The RPM package manager has been updated to provide audit events so that software package installation and updates can be tracked using the Linux Audit system. Software installation and upgrades using yum are also tracked.
Features specific to the x86_64 architecture
- Clevis support for TPM 2.0. The Clevis automated encryption framework that can automatically encrypt or decrypt data, or unlock LUKS volumes, has been updated to support the encryption of keys in a Trusted Platform Module 2.0 (TPM2) chip. Note that this feature is only available for x86_64 systems.
Features now available as a technology preview on the x86_64 architecture
- Block and object storage layouts for parallel NFS (pNFS)
- DAX (Direct Access) for direct persistent memory mapping from an application. This is under technical preview for the ext4 and XFS file systems
- Multi-queue I/O scheduling for SCSI (scsi-mq). Please note that this functionality is disabled by default
