Oracle Linux 6 DVDs Now Available

On Sunday 6 February 2011, Oracle Linux 6 was released on the Unbreakable Linux Network for customers with an Oracle Linux support subscription. Shortly after that, the Oracle Linux 6 RPMs were made available on our public yum server. Today we published the installation DVD images on Oracle Linux 6 is free to download, install and use. The full release notes are here, but similar to my recent post about Oracle Linux 5.6, I wanted to highlight a few items about this release.

Unbreakable Enterprise Kernel

As is the case with Oracle Linux 5.6, the default installed kernel on x86_64 platform in Oracle Linux 6 is the Unbreakable Enterprise Kernel. If you haven't already, I highly recommend you watch the replay of this webcast by Chris Mason on the performance improvements made in this kernel.

	# uname -r

The Unbreakable Enterprise Kernel is delivered via the package kernel-uek:

	[root@localhost ~]# yum info kernel-uek
	Installed Packages
	Name       : kernel-uek
	Arch       : x86_64
	Version    : 2.6.32
	Release    : 100.28.5.el6
	Size       : 84 M
	Repo       : installed
	From repo  : anaconda-OracleLinuxServer-201102031546.x86_64
	Summary    : The Linux kernel
	URL        :
	License    : GPLv2
	Description: The kernel package contains the Linux kernel (vmlinuz), the core of
	           : any Linux operating system.  The kernel handles the basic functions
	           : of the operating system: memory allocation, process allocation,
	           : device input and output, etc.

ext4 file system

The ext4 or fourth extended filesystem replaces ext3 as the default filesystem in Oracle Linux 6.
	# mount
	/dev/mapper/VolGroup-lv_root on / type ext4 (rw)
	proc on /proc type proc (rw)
	sysfs on /sys type sysfs (rw)
	devpts on /dev/pts type devpts (rw,gid=5,mode=620)
	tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
	/dev/sda1 on /boot type ext4 (rw)
	none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

Red Hat compatible kernel

Oracle Linux 6 also includes a Red Hat compatible kernel built directly from RHEL source. It's already installed, so booting it is a matter of editing /etc/grub.conf

	# rpm -qa | grep kernel-2.6.32

Oracle Linux 6 no longer includes a Red Hat compatible kernel with Oracle bug fixes. The only Red Hat compatible kernel included is the one built directly from RHEL source.

Yum-only access to Unbreakable Linux Network (ULN)

Oracle Linux 6 uses yum exclusively for access to Unbreakable Linux Network. To register your system with ULN, use the following command:

	 # uln_register


No Itanium Support

Oracle Linux 6 is not supported on the Itanium (ia64) platform.

What a Performance! MySQL 5.5 and InnoDB 1.1 running on Oracle Linux

The MySQL performance team in Oracle has recently completed a series of benchmarks comparing Read / Write and Read-Only performance of MySQL 5.5 with the InnoDB and MyISAM storage engines. 

Compared to MyISAM, InnoDB delivered 35x higher throughput on the Read / Write test and 5x higher throughput on the Read-Only test, with 90% scalability across 36 CPU cores. 

A full analysis of results and MySQL configuration parameters are documented in a new whitepaper

In addition to the benchmark, the new whitepaper, also includes:
- A discussion of the use-cases for each storage engine
- Best practices for users considering the migration of existing applications from MyISAM to InnoDB
- A summary of the performance and scalability enhancements introduced with MySQL 5.5 and InnoDB 1.1.

The benchmark itself was based on Sysbench, running on AMD Opteron "Magny-Cours" processors, and Oracle Linux with the Unbreakable Enterprise Kernel

You can learn more about MySQL 5.5 and InnoDB 1.1 from here and download it from here to test whether you witness performance gains in your real-world applications.

Oracle Linux 5.6 DVDs Now Available

On Thursday 20 January 2011, Oracle Linux 5.6 was released on the Unbreakable Linux Network for customers with an Oracle Linux support subscription. Today we published the installation DVD images on As always, Oracle Linux 5.6 is free to download, install and use. The release notes are here, but I wanted to highlight a few items about this release.

Unbreakable Enterprise Kernel

Oracle Linux 5.6 makes Unbreakable Enterprise Kernel the default kernel after installation unless you perform a custom installation. Note that Unbreakable Enterprise Kernel is available for the x86_64 platform only. Yesterday, Chris Mason, our Director of Linux Engineering delivered a webcast on the performance improvements we made to this kernel. I highly recommend you watch the replay.

[root@localhost ~]# uname -r
[root@localhost ~]# 

The Unbreakable Enterprise Kernel is delivered via the package kernel-uek:

[root@localhost ~]# yum info kernel-uek
Loaded plugins: rhnplugin, security
Installed Packages
Name       : kernel-uek
Arch       : x86_64

Red Hat compatible kernel

Oracle Linux 5.6 also includes a Red Hat compatible kernel built directly from RHEL source. It's already installed, so booting it is a matter of editing /etc/grub.conf

[root@localhost ~]# rpm -qa | grep kernel-2.6.18
Red Hat compatible kernel with bug fixes by Oracle

Finally, Oracle Linux 5.6 includes the Red Hat compatible kernel with critical bug fixes from Oracle. You can review the patches here. This kernel can be install directly from the DVD or from ULN if you're an Oracle Linux support customer.

Yum access to Unbreakable Linux Network (ULN)

Also new in this release is yum support for Unbreakable Linux Network.


Wednesday Jan 12, 2011 Q&A on Oracle's Unbreakable Enterprise Kernel recently published a Q&A on Oracle's Unbreakable Enterprise Kernel for Linux. The interview highlights the key benefits of Oracle's new offering and also offers an insight into our long and ongoing commitment to advancing Linux.

Here are some excerpts from the Q&A:

All enhancements made in the Unbreakable Enterprise Kernel are open source and have been made available to the Linux community. Oracle Linux, including both the kernels, is free to download, use and distribute. You can download the Unbreakable Enterprise Kernel at

Source code is available, including a public git repository with full changelog and individual patches and checkins for convenience.

Oracle Unbreakable Enterprise Kernel and Emulex HBA Eliminate Silent Data Corruption

Yesterday, Emulex announced that it has added support for T10 Protection Information (T10-PI), formerly called T10-DIF, to a number of its HBAs. When used with Oracle's Unbreakable Enterprise Kernel, this will prevent silent data corruption and help ensure the integrity and regulatory compliance of user data as it is transferred from the application to the SAN

From the press release:

Traditionally, protecting the integrity of customers' data has been done with multiple discrete solutions, including Error Correcting Code (ECC) and Cyclic Redundancy Check (CRC), but there have been coverage gaps across the I/O path from the operating system to the storage. The implementation of the T10-PI standard via Emulex's BlockGuard feature, in conjunction with other industry player's implementations, ensures that data is validated as it moves through the data path, from the application, to the HBA, to storage, enabling seamless end-to-end integrity.

Webcast: Eliminating Silent Data Corruption in Linux

Silent data corruption can be significantly detrimental and costly to a business. Oracle's Martin Petersen, our lead Linux Kernel developer for data integrity, has worked with the mainline kernel community to incorporate a data integrity specification into the Linux kernel that eliminates silent data corruption in Linux. This contribution enables comprehensive data integrity capabilities across the entire apps to disk stack, allowing customers to reduce costs and increase efficiencies.

Join Oracle's Linux technology experts for a webcast on Thursday, Dec. 16 at 9am US PT, as they discuss how Oracle Linux with its new Unbreakable Linux Kernel helps eliminate silent data corruption by reducing the potential for incorrect data to be writtem to the disk, decreasing application and database errors and system downtime.
