Latest Linux Innovations
Oracle Linux powers Oracle Autonomous Linux, extending autonomous
capabilities to Linux. Oracle Autonomous Linux is the first and only autonomous operating environment that helps greatly reduce complexity and human error to deliver increased cost savings, security, and availability for customers. 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 (RHEL). UEK is designed for enterprise workloads requiring stability, scalability, and performance, such as Oracle Database.

Oracle Linux is a great platform for application development and deployment.
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 and FIPS 140-2 validation of its cryptographic
    modules. Oracle has implemented the published Security Technical
    Implementation Guide (STIG) in Security Content Automation Protocol
    (SCAP) format.
  • 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 8.

Running Oracle Linux with UEK gives you additional advanced features and
security enhancements, including:

  • Unbreakable Enterprise Kernel – UEK for Oracle Linux provides the
    latest open source innovations and business-critical performance and
    security optimizations for cloud and on-premises deployment. UEK
    Release 6, based on the mainline Linux kernel version 5.4, is available on
    Oracle Linux 7 and 8. This release also includes many upstream
    enhancements.
  • Containers and Orchestration – Oracle Linux Cloud Native

    scalability requirements of large storage subsystems for Linux. It
    provides copy-on-write functionality, checksum functionality,
    transparent compression, transparent defragmentation, and integrated
    logical volume management.
  • 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 high performance and
    high availability, offering an open source, enterprise-class alternative to
    proprietary cluster file systems.
  • Data Integrity – Oracle Linux supports the T10 Protection Information
    Model (T10-PIM) to help prevent silent data corruption.

Flexible Support Options, Higher Value
Oracle is the only vendor in the industry that offers a complete Linux-based
solution stack – applications, middleware, database, management tools,
operating system, virtualization, hardware, engineered systems, and cloud. With Oracle as your Linux support provider, you have a single point of contact for all your support needs. Oracle delivers enterprise-class support for Oracle Linux, including premier backports, indemnification and testing.
Oracle Support for Oracle Linux installations is significantly lower in cost than competing vendors’ Linux support. You are free to decide which of your systems should be covered by a support subscription, and at which level each of them should be supported. This makes Oracle Linux an ideal choice for both your development and production systems. You decide which support coverage is the
best for each of your systems individually, while keeping all of them up-to-date and secure with the same level of bug fixes and security errata.
Oracle Linux is also the Linux development standard at Oracle. The same Oracle products customers deploy in their data center and in the cloud were developed using Oracle Linux. In addition, Oracle understands mission-critical application
requirements and Oracle Linux is developed and tested to provide the reliability,
scalability, security, and performance for these demanding enterprise workloads
