在2010年9月旧金山举行的Oracle OpenWorld大会上，Oracle为Linux推出了坚不可摧的企业级内核(Unbreakable Enterprise Kernel，简称：UEK)， UEK是一个高速的、新式的、可靠的Linux内核，是专门为Oracle的软件和硬件优化过的内核，它是Oracle Linux（以前称为“Oracle Enterprise Linux”）的一部分。
如今，硬件的发展日新月异，所以Linux也应该迅速发展以匹配最新的硬件，这非常重要。UEK与Oracle Linux的组合，使客户得到优化的快速访问、错误修正和其它新增强的功能。这一新产品是Oracle对Linux内核努力开发的成果，是目前主流的Linux内核的佼佼者，它使得Oracle Linux成为企业级客户的最佳选择。
Oracle公司的Linux操作系统、数据库、中间件和硬件团队的共同努力下，使UEK具有了以下超群的特点：
Oracle Exadata Database Machine和刚推出的 Oracle Exalogic Elastic Cloud正是基于这个坚不可摧的企业级内核，它们都体现出了极致的性能。
UEK是基于稳定的、主流的Linux kernel 2.6.32 发展而来，并将跟随这个内核的发展，用户可以同时受益于Oracle的创新和不断发展的Linux社区。目前它是为Oracle软件所唯一推荐使用的Linux内核。
Oracle Linux仍然可以使用 Red Hat Compatible Kernel（简称RHCK）。如果客户倾向于选择严格的Red Hat的兼容性，而不是选择一个优化过的Oracle系统及其出众的性能的话，他可以选择使用RHCK。
现有Oracle Linux 5和Red Hat Linux 5的客户可以轻松升级到UEK，而无需重新安装操作系统。在RHEL 5上运行的第三方应用软件可以不做任何改变而运行在包含UEK的Oracle Linux，重要的是它为最终用户带来了显著的性能和可靠性的提高。
根据Oracle Unbreakable Linux 支持计划，无论是运行Oracle UEK还是RHCK的客户，都能获得Oracle Linux的充分支持。
