Purpose

This document outlines Oracle's support Policy for customers using OCFS2 on Red Hat Enterprise Linux (RHEL) supported by Red Hat.

What is OCFS2?

OCFS2 is a general purpose shared-disk cluster file system for Linux capable of providing both high performance and high availability. As it provides local file system semantics, it can be used with almost all applications. Cluster-aware applications can make use of cache-coherent parallel I/Os from multiple nodes to scale out applications easily. Other applications can make use of the file system facilities to fail-over running application in the event of a node failure.

The file system is currently being used in virtualization (Oracle VM) in both the management domain, to host virtual machine images, and in the guest domain, to allow Linux guests to share a file system. It is also being used in database clusters (Oracle RAC), middleware clusters (Oracle E-Business Suite), appliances (SAP's Business Intelligence Accelerator), etc.


Software Update Policy for OCFS2 running on Red Hat Enterprise Linux

Oracle provides OCFS2 software and support for database file storage usage for customers who receive Red Hat Enterprise Linux (RHEL) operating system support from Red Hat and have a valid Oracle database version which supports OCFS2 usage and a valid database support contract. When a new RHEL update (only RHEL4 & RHEL5) comes out, Oracle will provide the current release of OCFS2 1.4 for it.  OCFS2 1.6 and later releases are only available with the Unbreakable Enterprise Kernel. Users wishing to upgrade to release 1.6 and later releases need to install this kernel via Unbreakable Linux Network (ULN). The older releases of OCFS2 will not be built for the new update versions of RHEL. OCFS2 is not supported for general filesystem use on RHEL without an Oracle Linux support subscription. Furthermore, OCFS2 software is not provided under Red Hat’s Extended Update Support (EUS or "z-stream”) or Extended Lifecycle Support (ELS).

Requirements for OCFS2 Software Updates


To receive software updates for OCFS2, both the release of the Oracle database in use and the version of Red Hat Enterprise Linux in use must be fully supported by Oracle and Red Hat respectively. Specifically, the Oracle Database release must be covered under Premier support or Extended support as defined in the Oracle Lifetime Support Policy for Oracle Technology Products and the RHEL version must be supported under one of the Production Lifecycle Phases as defined in the Red Hat Enterprise Linux Life Cycle

Red Hat Enterprise Linux 7 (RHEL7)

OCFS2 software is no longer available as a separate download for RHEL7.  OCFS2 software is included with Oracle Linux 7 and the Unbreakable Enterprise Kernel via ULN and public yum. ULN requires an Oracle Linux support subscription, even for those customers using OCFS2 just to store database files.

Red Hat Enterprise Linux 6 (RHEL6)

OCFS2 software is no longer available as a separate download for RHEL6.  OCFS2 software is included with Oracle Linux 6 and the Unbreakable Enterprise Kernel via ULN and public yum. ULN requires an Oracle Linux support subscription, even for those customers using OCFS2 just to store database files.

Red Hat Enterprise Linux 5 (RHEL5) x86, x86-64, Itanium, and PowerPC


OCFS2 software can be downloaded from the Oracle OCFS2 Downloads for Red Hat Enterprise Linux Server 5 page on Oracle's Free and Open Source Software portal. Updates and bug fixes to OCFS2 are provided for Linux kernels that are part the latest supported release of RHEL5 listed in the Enterprise Linux Supported Releases document and three update releases prior to that. For example, if the latest supported release of RHEL is RHEL5, Update 5 (RHEL5.5), then updates to OCFS2 will be provided for RHEL5.2, RHEL5.3, RHEL5.4 and RHEL5.5 kernels.

Red Hat Enterprise Linux 4 (RHEL4) x86, x86-64, Itanium, and PowerPC


OCFS2 software can be downloaded from the Oracle OCFS2 Downloads for Red Hat Enterprise Linux 4 AS page on Oracle's Free and Open Source Software portal. RHEL4 is no longer in a Production Lifecycle Phase of support by Red Hat. No new fixes will be provided for OCFS2 for RHEL4. Only pre-existing  updates and bug fixes to OCFS2 are provided for RHEL4  now.
