Oracle Linux is an enterprise-class Linux distribution supported by Oracle and built from source packages for Red Hat Enterprise Linux (RHEL). Some of the special features of Oracle Linux include a custom-build and rigorously-tested Linux kernel called “Oracle Unbreakable Kernel”, tight integration with Oracle’s hardware and software products including most database applications, and “zero downtime patching” – a feature that enables administrators to update the kernel without a reboot.

Oracle Enterprise Linux is a freely distributed operating system based and compatible with the Red Hat Enterprise Linux distribution. It is an enterprise-ready server Linux OS designed to be used on small and medium-sized businesses. Oracle Linux is free to download, use and distribute and is provided in a variety of installation and deployment methods. Installation media (ISO images) for Oracle Linux (and Oracle VM) are freely available from the Oracle Software Delivery Cloud.

The Oracle Linux operating system is engineered for open cloud infrastructure. It delivers leading performance, scalability, reliability and security for enterprise SaaS and PaaS workloads as well as traditional enterprise applications. Oracle Linux Support offers access to award-winning Oracle support resources and Linux support specialists, zero-downtime updates using Ksplice, additional management tools such as Oracle Enterprise Manager and lifetime support, all at a low cost. Unlike many other commercial Linux distributions, Oracle Linux is easy to download and completely free to use, distribute and update.

Latest Linux Innovations Oracle Linux comes with a choice of two kernels, the Unbreakable Enterprise Kernel (UEK), which is installed and enabled by default, and the Red Hat Compatible Kernel. UEK tracks the latest Linux kernel releases, supplying more innovation than other commercial Linux kernels while providing binary compatibility with applications certified to run on Red Hat Enterprise Linux. UEK is designed for enterprise workloads requiring stability, scalability and performance, such as Oracle Database. Oracle Linux delivers advanced features for supporting and optimizing the latest enterprise hardware and software. For example:

• Ksplice Zero Downtime Updates –

Available to Oracle Linux Premier Support customers, Ksplice technology updates the kernels, hypervisors and critical user space libraries without requiring a reboot or interruption. Known Exploit Detection in Ksplice enables auditing and alerting for known privilege escalation vulnerabilities. Only Oracle Linux offers this unique capability, making it possible to keep up with important kernel and user space updates without the operational cost and disruption of rebooting for every update.

• Security and Compliance – Oracle Linux 7 has received both a Common Criteria (CC) Certification which was performed against the National Information Assurance Partnership (NIAP) General Purpose Operating System Protection Profile (OSPP) v4.1 as well as a FIPS 140-2 validation of its cryptographic modules.
• XFS File System – XFS is a journaling file system known for extreme scalability with near native I/O performance. XFS is the default filesystem for Oracle Linux 7 and Oracle Linux 8. Beginning with Oracle Linux 6.4, customers with Premier Support subscriptions can receive support for the XFS file system at no additional charge.
• Data Integrity – Oracle Linux supports the T10 Protection Information Model (T10- PIM) to help prevent silent data corruption.

Running Oracle Linux with UEK gives you additional advanced features and security enhancements. Some of which are:

• Containers and Orchestration – Safely and securely run multiple applications on a single host, without the risk of interference with each other. Docker containers are lightweight and resource friendly, which saves on rack space and power. Oracle Container Runtime for Docker and Oracle Container Services for use with Kubernetes provide a comprehensive container and orchestration environment for the delivery of microservices and next generation application development.
• DTrace – DTrace is a comprehensive dynamic tracing framework that provides a powerful infrastructure to permit administrators, developers and service personnel to concisely answer arbitrary questions about the behavior of the operating system and user programs in real time.
• AMD Secure Memory Encryption (SME) – Oracle Linux 7 with UEK Release 5 enables the hardware accelerated memory encryption, available on AMD EPYC processors based systems, for data-in-use protection.
• Oracle Cluster File System 2 (OCFS2) – OCFS2 is a general purpose, extent-based clustered file system that Oracle developed and contributed to the Linux community. It provides an open source, enterprise-class alternative to proprietary cluster file systems, and provides both high performance and high availability.
• Oracle Workload Optimizations – Some of the many optimizations available are:
• Enhanced memory performance, by attempting to better locate a process near its memory and better placement of workloads that do not fit on one NUMA node.
• Up to 3.6x performance improvement of SPECjbb through optimizations that help eliminate lock contention.
• Simple to use SSDs as a block cache for slower block devices with bcache. Supports many millions of IOps on NVM-Express and high-end PCI-E devices with a new, scaled multiqueue block layer subsystem.
