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 edelivery.oracle.com/linux. 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 : http://www.kernel.org/

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.

  • entricular Tuesday, February 22, 2011
    I wish Oracle could send out these Oracle Linux DVD's like AOL was sending out AOL cdroms in the mail.
    At least flood the market with your product for FREE so users could decide if they like the product.
    Not sure if the general users will buy Oracle Linux the same way Microsoft operating systems are sold.

    Can UBUNTU 10.04 LTS be upgraded by this latest Oracle Linux6 ? Tks in advance .
  • Gilles Haro Thursday, February 24, 2011
    Hello Sergio,
    What about the oracle-validated package ?
    Is Database 11gR2 supported with this release ?
    Why do we only see MySQL and Postgres in the "database server" configuration ? I would have liked to find oracle-validated in there.
    Thanks a lot,
  • Hansley Chadee Wednesday, March 2, 2011
    is this version certified for ebusiness suite technology stack i.e. oracle 11GR1 and 10G apps tier ?
  • Sergio Friday, March 18, 2011
    Certification of Oracle Database with Oracle Linux 6 is in progress. Stay tuned.

    Is it possible to Upgrade from OEL 5.x to OL 6.0?
  • Efrain Sanchez Wednesday, April 13, 2011
    You can also install manually the oracle-validated package
    yum install compat-db compat-gcc-34 compat-gcc-34-c++ compat-libstdc++-296 compat-libstdc++-33 binutils control-center gcc gcc-c++ glibc glibc-common glibc-headers glibc-devel libstdc++ libstdc++-devel make sysstat libaio libaio-devel expat fontconfig freetype zlib libXp libXp-devel openmotif22 openmotif elfutils-libelf elfutils-libelf-devel unixODBC unixODBC-devel

    Keep in mind that the oracle-validated package does more than installing the required RPMs. It also creates the necessary users and groups, adjusts kernel settings, etc.
