Friday Spotlight: Focus On Oracle Linux at Oracle OpenWorld 2014

Happy Friday!

One of my favorite moments of the Oracle OpenWorld process is when the Schedule Builder tool opens up and attendees can start planning their schedules. That happened this week, and you can access it at the main Oracle OpenWorld page by clicking the "Sessions" menu and then "Schedule Builder".

In addition to Schedule Builder, another really great tool the Oracle OpenWorld team provides is called the Focus On document. These are dynamic HTML pages that group together similar topics to make it easy to identify things that would be interesting to you at the show.

The Focus on Oracle Linux document has been live for a few weeks, but up until this week it didn't have scheduling info, so it's much more interesting to take a look at now!

As I mentioned, the Focus On Document is dynamically generated when you click on it, so it gives you an up to the second view of the Oracle Linux content at the show. In fact, there should even be a couple of more additions to this schedule as a few more of the scheduling items get finalized, so the Focus On is a great way to keep track of those new items, too. And if you're logged in to your Oracle account, you can even click the little + icon on each session to register right then and there.

If you're interested attending Oracle OpenWorld and you are interested in Oracle Linux, please bookmark it. It's very handy to have, especially on your mobile device, at the show!

And look to this space for a lot more Oracle OpenWorld content in the coming weeks as we roll on toward toward the show starting on October 28 in San Francisco!

Ahoy! Cast off with Docker on Oracle Linux

There's no need to upgrade to Oracle Linux 7 to start playing with Docker: we've built it for Oracle Linux 6 and the Unbreakable Enterprise Kernel Release 3 and released it into the addons channel on This release of Docker uses the native libcontainers engine by default as well as supporting btrfs as the storage engine. 

If you've already got Oracle Linux 7 installed, don't worry we have you covered: we've released Docker for Oracle Linux 7 as well.


To install Docker on Oracle Linux 6:

  1. Enable the ol6_addons channel in /etc/yum.repos.d/public-yum-ol6.repo
  2. Run:
    # yum install docker

To install Docker on Oracle Linux 7:

  1. Enable the ol7_addons channel in /etc/yum.repos.d/public-yum-ol7.repo
  2. Run:
    # yum install docker

Enable btrfs support

Docker uses device-mapper devices as the default storage engine. To switch to using btrfs as the storage engine, ensure that /var/lib/docker is mounted on a btrfs filesystem. Check Chapter 5 of the Oracle Linux Administrator's Solutions Guide for more details on how to create and mount btrfs filesystems.

To enable btrfs support for Docker on Oracle Linux:

  1. Ensure that /var/lib/docker is on a btrfs filesystem
  2. Edit /etc/sysconfig/docker and add "-s btrfs" to the other_args fields.
  3. Restart the Docker daemon:
    # service docker restart

Enabling and starting Docker

To enable the Docker daemon on system boot and start Docker on OL6:

# chkconfig docker on

# service docker start

To enable the Docker daemon on system boot and start Docker on OL7:

# systemctl enable docker.service

# systemctl start docker.service

Checking Docker status

To check that Docker is up and running on OL6:

# service docker status

To check that Docker is up and running on OL7:

# systemctl status docker.service

You can also get more information from Docker itself:

# docker info

# docker version

Once you have Docker up and running, follow the upstream Docker documentation to get started. 

Known Issues

Docker unmounts btrfs filesystems on shutdown

If you're running Docker using the btrfs storage engine and you stop the Docker service, it will unmount the btrfs filesystem during the shutdown process. You should ensure the filesystem is mounted properly prior to restarting the Docker service. On Oracle Linux 7, you can use a systemd.mount definition and modify the Docker systemd.service to depend on the btrfs mount defined in systemd.

SElinux support with btrfs on Oracle Linux 7

SElinux must be set to Permissive or Disabled in order to use the btrfs storage engine on Oracle Linux 7.

Friday Spotlight: Getting Started with Oracle VM, Oracle Linux, and OpenStack

Happy Friday!

You might have seen Ronen Kofman’s announcement earlier in the week regarding the technology preview of OpenStack Icehouse with Oracle Linux and Oracle VM.

Technology Preview of OpenStack Icehouse with Oracle Linux and Oracle VM - Now Available

On May we announced the technology preview of the OpenStack Havana release with Oracle Linux and Oracle VM, today we are releasing the technology preview of the Icehouse release. This release is a fast and easy way to deploy OpenStack giving customers an excellent starting point to deploy Icehouse and test it in their environment. We made sure that the deployment process remains the same as it was for Havana using few simple steps so anyone ,even with no prior experience with OpenStack, can install and try it out. The Icehouse release is an important step in the process of making OpenStack a first class enterprise solution, it continues the strong maturity curve of OpenStack and introduces more plug-ins , more bug fixes and around 350 new features.

Oracle Distribution of OpenStack for Linux will become part of Oracle Linux and Oracle VM premier support subscriptions at no additional cost. Like Oracle Linux and Oracle VM customers can use it for free or, shall they choose to, purchase support from Oracle and receive a complete production support for their deployment. As we stated previously, Oracle will support deployment of Oracle Linux and Oracle VM with any distribution of OpenStack the customer chooses and we will continue working with third party vendors to assure that we can integrate with their solution.

Please join us at Oracle OpenWorld on September 28th where we will have a special focus on OpenStack. At Oracle OpenWorld customers will have a chance to hear more about Oracle’s OpenStack strategy and products as well as see live demos and try them in the hands on labs.

Some technical details about the Icehouse tech preview release:

The download instructions are available here and the getting started guide is available here, for convenience we outline the few additional steps needed to complete the deployment
When deploying an Icehouse compute node with Oracle VM users have to perform two additional steps as part of their post-install steps. The two additional steps include setting the following parameters:

openstack-config --set /etc/nova/nova.conf libvirt cpu_mode none
openstack-config --set /etc/nova/nova.conf libvirt virt_type xen

When deploying an Icehouse compute node with Oracle Linux the two additional steps include setting the following parameters:

openstack-config --set /etc/nova/nova.conf libvirt virt_type kvm
openstack-config --set /etc/nova/nova.conf libvirt cpu_mode none

In both cases the operation needs to completed by restarting the nova-compute service:

service openstack-nova-compute restart
