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.

You can learn about systemd and much more by taking the Oracle Linux 7: System Administration course. You can take this instructor-led, 5-day course, through the following formats:

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!

Oracle Linux Users Participate in Salary Survey

Linux is one of the hottest buzzwords in IT hiring. If you can prove that you know your stuff when it comes to Linux, then you can command a fat salary. And what better way to prove that your skills are up to snuff than with a certification?

How much can you add to your income with a Linux certification? Contribute to getting an accurate answer to this question by taking a minute to fill in this survey: http://certmag.com/salary-survey-plus-linux/. The results will be available in the August edition of the Certification Magazine.

Being one of the top Linux curriculum in the industry, the Oracle Linux certifications will feature in this survey.

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: A busy week, and Spacewalk and Ksplice

Happy Friday!

With Oracle OpenWorld Latin America with several Oracle Linux and virtualization sessions and demos, and our booth at Red Hat Summit, it’s been a busy and fun week here at Oracle.

For today's spotlight, I’m going to reach back into the archives to highlight something that I think is particularly cool. You probably know about Spacewalk for managing your Linux deployments, and you also probably know about our Ksplice feature that allows for zero-downtime kernel updates. Taken together, these tools give you a streamlined way to keep your Oracle Linux systems up to date. And, in fact, this past winter we did a webcast on this exact subject, which is available as an archive. It would be nice background listening as you wrap-up your Friday afternoon:

Spacewalk and Ksplice: Keeping Oracle Linux Systems Up to Date and Secure (webcast archive)

See you next week!

FRIDAY SPOTLIGHT: Getting Started with Docker on Oracle Linux

Happy Friday everyone! 

We have a great technical article for you this Friday.  In this article, you learn how to customize a Docker container image and use it to instantiate application instances across different Linux servers. This article describes how to create a Dockerfile, how to allocate runtime resources to containers, and how to establish a communication channel between two containers (for example, between web server and database containers). 

Ginny Henningsen quotes "Docker is exciting because it can easily capture a full application environment into a virtual container that can be deployed across different Linux servers. System administrators and software developers are learning that Docker can help them deploy application images on Linux quickly, reliably, and consistently—without dependency and portability problems that can inject delays into planned deployment schedules. Docker containers can define an application and its dependencies using a small text file (a Dockerfile) that can be moved to different Linux releases and quickly rebuilt, simplifying application portability. In this way, "Dockerized" applications are easily migrated to different Linux servers where they can execute on bare metal, in a virtual machine, or on Linux instances in the cloud. "

As shown in Figure 1, Docker containers consume fewer resources than "heavyweight" hypervisor-based solutions. Hypervisor-based solutions host a full-blown operating system instance in each virtual machine guest, but this also allows them to support different operating systems. (Oracle VM, for example, can host Oracle Linux, Oracle Solaris, and Microsoft Windows in virtual machines.)
