Friday Spotlight: Oracle Cloud Days Around the World

Happy Friday!

I wanted to bring some attention to a great series of events that kicked off this week in the US in Chicago, Oracle Cloud Day: Transforming Your Tomorrow.

This is a worldwide set of events that will help you understand how cloud is being used today, and how Oracle can help you leverage cloud technology to meet your business goals. These in person events talk about the entire Oracle portfolio, and many locations feature a dedicated session on Oracle Linux, Oracle VM, and Oracle OpenStack for Oracle Linux. If you're in the areas where these events are being held, I highly recommend them!

Head on over to the event home page and the schedule page to see if there is one happening near you.

Have a great week!

Friday Spotlight: Building the Modern Cloud-Enabled Data Center

Happy Friday!

Thanks so much to everyone that stopped by our booth and went to our sessions at LinuxCon North America 2015! We had a great time and it was fantastic getting the opportunity to meet and speak with many of you in person.

Some of the things that are top of mind for Linux users are (obviously!) the cloud impact on data center design, container technologies, OpenStack, security, and so on. So I looked through our archive to find a webcast that I think does a great job outlining how Oracle Linux approaches these things. If you're looking for a brief overview this Friday afternoon, head on over to this webcast archive and have a watch:

Building the Modern Cloud-Enabled Data Center with Oracle Linux 7

We'll see you next week!

Friday Spotlight: Software updates, LinuxCon, and more!

Happy Friday!

It's been a busy period here in the Oracle Linux team, so I thought I'd do a highlight post with links to some of the big things that are happening:

- LinuxCon North America starts in just 10 days, and Oracle is a sponsor. The conference features a keynote by Oracle Senior Vice President Linux and Virtualization Wim Coekaerts. If you're there, you don't want to miss it.

- Speaking of Wim and LinuxCon, there is a short video to give you a peek into what Wim will be talking about.

- We released Oracle Linux 6.7.

- We released Unbreakable Enterprise Kernel Release 3 Quarterly Update 6.

There's a lot of other great stuff going on, too, from Oracle Private Cloud Appliance training, to Oracle looking for people interested in working to design and develop technical training, and a new linux.com article on sysadmin job interview questions, featuring thoughts from Oracle Linux product management.

Have a great week and we'll see you next Friday!

Wim Coekaerts is Keynote speaker at LinuxCon North America

Oracle is one of the biggest contributors to Linux but it’s also at the forefront of exploring what is possible with cloud computing and containers, including integrations with Docker and contributions to the Open Container Initiative. 

This year Oracle is sponsoring LinuxCon North America and Wim Coekaerts, Sr.VP Oracle Linux and Virtualization Engineering will be keynote speaker. He will be talking at the event specifically about how the cloud revolution is changing the role of the operating system, a very relevant topic for attendees. Amanda McPherson of Linux Foundation, spoke to Wim at Oracle’s campus in Redwood Shores a few weeks ago, and in this short video preview, Wim tells if the operating system still matters in a world of virtualization and containers and how that impacts application development.

systemd, The New System and Service Manager in Oracle Linux 7

Oracle Linux 7 includes systemd, the new system and service manager that replaces the Upstart init daemon. While providing backward compatibility for legacy Oracle Linux 6 service scripts. systemd offers the following benefits over init:

  • Services are started in parallel wherever possible using socket-based activation and D-Bus.
  • Daemons can be started on demand.
  • Processes are tracked using control groups (cgroups).
  • Snapshotting of the system state and restoration of the system state from a snapshot is supported.
  • Mount points can be configured as systemd targets.

Friday Spotlight: Why Virtualization Drives the Cloud

Happy Friday!

We have a brand new digital white board video for you this week on why virtualization drives the cloud. The host is Oracle VM Product Management Director John Priest, and while the video is focused on Oracle VM, it has some great general purpose information in it, too. It would be interesting to folks interested in Oracle VM, Oracle Linux, and just cloud infrastructure in general.

Click here or the thumbnail below to head over to Oracle Media Network to give it a watch:

 Hope you enjoy it and have a great week!

Friday Spotlight: Oracle VM VirtualBox 5.0 is out!

Happy Friday!

I know a lot of folks use Oracle VM VirtualBox to run Oracle Linux VMs. I do this myself every day. The ability to run multiple machines with different operating systems on a laptop is incredibly helpful. For example, you can do Docker development in Oracle Linux on your Macbook. Or if you're running Linux as your main OS, you could have a Windows VM, maybe for some pesky corporate apps that won't run on Linux. The possibilities are just endless.

Oracle VM VirtualBox 5.0 was released this week, with a number of key features. Things like:

  • Runtime disk encryption
  • Drag and drop between nearly all host and guest combinations (including my typical Mac host->Oracle Linux guest setup)
  • USB 3.0 support
  • Headless launch support (say you need a local server VM running in the background!)
  • Performance improvements with paravirtualization for newer Linux and Windows guests

And a lot more.

Have a look at the Oracle Virtualization blog post for more details, and go grab Oracle VM VirtualBox 5.0 here.

Have a great week!

Friday Spotlight: Shiny new pages for OSS, Public Yum, and ULN!


Happy Friday and a happy holiday weekend to those of you in the US!

It might be obvious, but the Oracle Linux and virtualization teams are heavily involved in open source. For quite some time, we’ve had a site that describes the open source projects the teams are involved in. This site was just updated with a new look and feel and additional content. My favorite part is a history section going by to 2001. Check it out:


I’m also excited to highlight the new look and feel for the Oracle Linux Yum server (we also call it "Public Yum"):


And you also might not yet have noticed that the Unbreakable Linux Network ALSO has a shiny new look and feel:


Just some improvements to make working with these sites easier for folks. We hope you enjoy them!

Friday Spotlight: Understanding NVMe Support on Oracle Linux

Non-volatile memory express, also known as NVMe or NVM Express, is an interface specification that aims to enable a solid-state drive (SSD) to make the most effective use of the high-speed Peripheral Component Interconnect Express (PCIe) bus in a computer. 

NVMe has been supported in the mainline upstream release of Linux since kernel 3.3. Check out the commit log message for NVMe, and you can find pages of updates going back to 2011. The first distributions to support NVM Express focused on the add-in card form factor (without support for hot plug). 

Oracle was the first vendor to support NVMe hot-plug in a Linux distribution and today hot-plug is supported in all Oracle Linux releases beginning with Oracle Linux 6.4.

Oracle Linux NVMe Support *

Oracle Linux includes inbox support for NVMe SSDs beginning with Unbreakable Enterprise Kernel (UEK) Release 3 in October 2013. UEK R3 is supported in Oracle Linux 6.4 (or later) and Oracle Linux 7 (or later), and is enhanced to provide NVMe feature support consistent with mainline kernel 3.19, including hot-plug support (although without the block_mq feature).
