Oracle Linux, formerly known as Oracle Enterprise Linux, is a Linux distribution based on Red Hat Enterprise Linux, repackaged and sold by Oracle, available under the GNU General Public License (GPL) since late 2006.[3]

Oracle Linux can be freely downloaded through Oracle's E-delivery service, and can be deployed and distributed without cost. [4] Commercial technical support is available through Oracle's Oracle Unbreakable Linux Support program, which supports Oracle Linux, and existing RHEL or CentOS installations (i.e. without reinstallation[5]).[3] As of 2011, Oracle Linux has over 8,000 customers subscribed to the support program.[6] [7]

[edit] RHEL compatibility

Oracle Corporation distributes Oracle Linux with two kernels:

Oracle claims that the Unbreakable Enterprise Kernel is compatible with RHEL, and Oracle middleware and 3rd-party RHEL-certified applications can be installed and run unchanged on Unbreakable Enterprise Kernel. However, for users requiring strict compatibility with Red Hat or for users running kernel modules dependent on specific kernel versions, the Red Hat Compatible Kernel offers 100% compatibility with Red Hat Enterprise Linux.[3]

[edit] Hardware compatibility

Oracle Linux is certified on servers from IBM,[10] HP, [11] Dell,[12] and Cisco.[13] In 2010, Force10 announced support for Oracle VM and Oracle Linux.[14] Oracle Linux is also available on Amazon EC2 as an Amazon Machine Image. [15]

Oracle/Sun servers and blades with x86-64 processors can be configured to ship with Oracle Linux.[16]

[edit] Virtualization support

Under the Unbreakable Linux program, Oracle Linux supports KVM and Xen.[3]

Other Oracle products (including Oracle Database and other Oracle Applications) are only supported under the Xen-based Oracle VM.[17]

[edit] Oracle Linux deployment inside Oracle

Oracle Linux is used by Oracle internally to lower IT costs. Oracle Linux is deployed on more than 42,000 servers by Oracle Global IT; Oracle On Demand, Oracle University, and Oracle's technology demo systems also run Oracle Linux.[3]

Software developers at Oracle develop Oracle Database, Fusion Middleware, Oracle Grid Engine, E-Business Suite and other Oracle Applications on Oracle Linux.[3]

[edit] Oracle Linux-related products

Oracle Linux is used as the underlying operating system for the following appliances. [18]

[edit] Oracle Linux specific addition

  • Ksplice - Oracle acquired Ksplice Inc in 2011, and offers Oracle Linux users Ksplice to enable hot kernel patching[19]
  • DTrace - Oracle ported DTrace from Solaris as a Linux kernel module[20]

[edit] Benchmark submission

In January 2012, Oracle submitted a TPC-C benchmark result using a Sun Fire server running Oracle Linux and Unbreakable Enterprise Kernel.[21] With 8 Intel Xeon processors running Oracle DB 11 R2, the system is able to handle over 4.8 million tpmC. The server is the third fastest TPC-C non-clustered system and is the fastest x64 non-clustered system.[22] [23]

[edit] Future SPARC version

In December 2010, Oracle CEO Larry Ellison announced that future versions of Oracle Linux will run on Oracle's SPARC and UltraSPARC T-series (Niagara) platforms.[24]
