Oracle Linux

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

Oracle Linux can be downloaded through Oracle’s E-delivery service or from a variety of mirror sites, and can be deployed and distributed without cost.[4] Commercial technical support is available through Oracle’s Oracle Linux Support program, which supports Oracle Linux, and existing RHEL or CentOS installations (i.e. without reinstallation[5]).[3] As of 2013, Oracle Linux has over 11,000 customers subscribed to the support program.

RHEL compatibility

Oracle Corporation distributes Oracle Linux with two alternative kernels:

Oracle claims that the Unbreakable Enterprise Kernel is compatible with RHEL, and that Oracle middleware and third-party RHEL-certified applications can install and run unchanged on the Unbreakable Enterprise Kernel. 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]

Hardware compatibility

Oracle Linux is certified on servers from IBM,[11] Hewlett-Packard,[12] Dell,[13] Lenovo,[14] and Cisco.[15] In 2010, Force10 announced support for Oracle VM and Oracle Linux.[16] Oracle Linux is also available on Amazon EC2 as an Amazon Machine Image,[17] and Microsoft Windows Azure as a VM Image.[18]

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

Virtualization support

Under the Oracle Linux Support program, Oracle Linux supports
KVM
and Xen.

Other Oracle products are only supported under the Xen-based Oracle VM
