Что такое oracle unbreakable linux
The Unbreakable Enterprise Kernel for Oracle Linux provides the latest innovations from upstream development to customers who run Oracle Linux in the data center.
Starting with Oracle Linux 5 Update 6 and later Oracle Linux kernels, the Unbreakable Enterprise Kernel is included and enabled by default. It is based on a recent stable mainline development Linux kernel, and also includes optimizations developed in collaboration with Oracle Database, Oracle middleware, and Oracle hardware engineering teams to ensure stability and optimal performance for the most demanding enterprise workloads.
Oracle highly recommends deploying the Unbreakable Enterprise Kernel in your Oracle Linux environment, especially if you run enterprise applications. However, using Unbreakable Enterprise Kernel is optional. If you require strict Red Hat Enterprise Linux (RHEL) kernel compatibility, then Oracle Linux also includes a kernel compatible with the RHEL Linux kernel, compiled directly from the RHEL source code.
You can obtain more information about the Unbreakable Enterprise Kernel for Oracle Linux at the following URL:
The Unbreakable Enterprise Kernel for Oracle Linux is the standard kernel used with Oracle products. The build and QA systems for Oracle Database and other Oracle products use the Unbreakable Enterprise Kernel for Oracle Linux exclusively. The Unbreakable Enterprise Kernel for Oracle Linux is also the kernel used in Oracle Exadata and Oracle Exalogic systems. Unbreakable Enterprise Kernel for Oracle Linux is used in all benchmark tests on Linux in which Oracle participates, as well as in the Oracle Preinstallation RPM program for x86-64.
Oracle Ksplice, which is part of Oracle Linux, updates the Linux operating system (OS) kernel, while it is running, without requiring restarts or any interruption. Ksplice is available only with Oracle Linux.

Getting Started with Oracle Unbreakable Enterprise Kernel Release 2
by Lenz Grimmer, March 2012
How to replace your Linux kernel with Release 2 of Oracle’s Unbreakable Enterprise Kernel.
Introduction
This article describes how you can update your Oracle Linux systems to the latest version of the Unbreakable Enterprise Kernel. By switching to the latest Unbreakable Enterprise Kernel, you can get the latest innovations in mainline Linux. Switching is easy—applications and the operating system remain unchanged. There is no need to perform a full re-install; only the relevant RPM packages are replaced. You can obtain future updates easily from the Unbreakable Linux Network to keep your systems fully patched and secured.
At the time of this publishing, Unbreakable Enterprise Kernel Release 2 (version 2.6.39) was just released as an update for the first Unbreakable Enterprise Kernel (version 2.6.32). To learn more about the new features and benefits of using Unbreakable Enterprise Kernel Release 2, see the feature overview page and the release notes.
The examples used below are based on these versions, but a similar procedure should work for future kernel update releases as well.
This article describes two different installation methods:
- The first method, using the Oracle Unbreakable Linux Network, requires a valid Oracle Linux Support subscription.
- The second method involves obtaining the Unbreakable Enterprise Kernel from the public yum package repository.
It is assumed that you already have Oracle Linux 5 or 6 installed and you are running either the Unbreakable Enterprise Kernel Release 1 (2.6.32) or the Red Hat–compatible kernel (2.6.18 on Oracle Linux 5, 2.6.32 on Oracle Linux 6).
Unbreakable Enterprise Kernel Release 2 can be installed on Oracle Linux 5 Update 8 or newer, as well as on Oracle Linux 6 Update 2 or newer. If you’re still running an older version of Oracle Linux, make sure you first update your system to the latest available minor release.
About the Unbreakable Enterprise Kernel for Oracle Linux
Oracle Linux with the Unbreakable Enterprise Kernel is Oracle’s fully supported, tested, and certified Linux operating system for the enterprise. Oracle Linux is free to download, use, and distribute, and it is optimized to run Oracle hardware, databases, and middleware. You can obtain ISO images of the installation media from the Oracle Software Delivery Cloud without charge (requires registration).
The Oracle Linux base distribution is 100% userspace-compatible with Red Hat Enterprise Linux (RHEL). However, the Unbreakable Enterprise Kernel is released on an independent schedule and is always based on a recent version of the mainline Linux kernel. As a result, it delivers the latest innovations from mainline Linux, combined with tested performance and stability. It is installed and booted by default; major updates of the Unbreakable Enterprise Kernel are usually published every 12 to 18 months.
Installing the Unbreakable Enterprise Kernel from the Unbreakable Linux Network
The Unbreakable Linux Network (ULN) is a comprehensive and easy-to-use Website for Oracle Linux Support subscribers, which offers access to Linux software patches, updates, and fixes, along with documentation and support policies.
In order to get access to ULN you need to have a valid support subscription, which you can purchase online from the Oracle Linux Store.
Once you have successfully logged in to ULN, you first need to register your system. See the Unbreakable Linux Network FAQ for more details about this process. When you register a server, it is automatically subscribed to a channel that provides the latest Oracle Linux packages and updates for the respective version and architecture.
Continuously updated packages of the Unbreakable Enterprise Kernel are made available on ULN in a separate channel; you need to be subscribed to the appropriate channel for your system’s operating system version.
Once your system is registered with ULN, you need to subscribe the system to the Unbreakable Enterprise Kernel Release 2 channel for your distribution.
The following example shows how to use the ULN Website to subscribe an Oracle Linux 6.2 (64-bit) system running Unbreakable Enterprise Kernel Release 1.
- Log in to ULN with your user account and click the Systems tab to get a list of all systems that are currently registered with ULN (see Figure 1).
Figure 1. ULN System Profiles
When you click a machine name, you will see the system’s details, the channels it is subscribed to, and the list of available patches (see Figure 2).
Figure 2. ULN System Details
When you click a machine name, you will see the system’s details, the channels it is subscribed to, and the list of available patches (see Figure 2).
Click Manage Subscriptionsto subscribe the system to the additional channel that provides the updated Unbreakable Enterprise Kernel packages. The channel will be displayed in the list of available channels (see Figure 3).
Figure 3. ULN List of Available Channels
Figure 4. Channel Added to List of Subscribed Channels
Your system is now subscribed to receive the latest build of Unbreakable Enterprise Kernel and all subsequent future updates.
The naming scheme for the Unbreakable Enterprise Kernel channels is the following:
ol6_x86_64_UEK_latest
Verify that the subscription succeeded by running yum repolist on the system:
As you can see, the ol6_x86_64_UEK_latest repository is now enabled in addition to the default update repository.
To see the list of available updates for this newly added repository, use the following command:
Listing 1. Downloading and Installing Available Updates
Congratulations, you have successfully installed the latest version of the Unbreakable Enterprise Kernel! Now, skip to the Postinstallation Tasks and Next Steps section to finish the installation.
Installing the Unbreakable Enterprise Kernel from the Public Yum Repositories
The initial releases of Oracle Linux and the Unbreakable Enterprise Kernel are freely available as individual RPM packages from the public yum repository.
You just need to add and enable the dedicated Unbreakable Enterprise Kernel yum repository to update to the current kernel version. This can be done by adding the appropriate yum repository configuration file and enabling the respective repository.
- Start by downloading the corresponding repository configuration file.
For Oracle Linux 5, run the following command:
For Oracle Linux 6, run the following command:
Listing 2. Checking for Updates and Installing the New Packages
The Unbreakable Enterprise Kernel Release 2 has now been installed.
Postinstallation Tasks and Next Steps
At this point, you need to reboot your system in order to enable the newly installed kernel. You will notice that the GRUB boot menu includes a new entry for the updated kernel version, which will be booted by default.
After rebooting, you can verify the kernel version number by running uname -r:
You can now enjoy the latest improvements and developments in Linux delivered by the Unbreakable Enterprise Kernel, without having to re-install your entire operating system or applications.
The dedicated Unbreakable Enterprise Kernel repository also includes additional and updated packages and tools that are required to enable or work with new kernel features. Some of these are updates for already existing packages, while others need to be installed manually.
For example, if you want to start using the B-tree file system (Btrfs), make sure you install the btrfs-progs package, as shown in Listing 3.
Listing 3. Installing the Package for Btrfs
Similarly, there will be additional packages for other newly introduced features, for example, features for using and managing Linux Containers (lxc).
Conclusion
This article described two methods you can use to update your Oracle Linux systems to the latest version of the Unbreakable Enterprise Kernel. Future updates can be obtained easily from the Unbreakable Linux Network to keep your systems fully patched and secured. With the help of Ksplice, applying these updates can even be performed without having to schedule any downtime or reboots.
