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:

See you next week!

Friday Spotlight: The Power of The Ksplice Feature of Oracle Linux Video

Happy Friday!

I'm really excited to share this week's Friday Spotlight with you. Oracle Senior Vice President of Linux and Virtualization Wim Coekaerts sat down with Director of Product Management Michele Casey and Senior Development Manager Jamie Iles to talk about Ksplice.

In the video, they go into a lot of detail about why Ksplice is a production-ready tool for keeping systems up to date. A highlight for me is the discussion featuring a real world example of an Oracle Linux 6.2 system from 2011, and how a system like that can be patched over time with all the important CVEs and security updates without a single reboot -- no rebooting literally for years. For production systems, you can just keep the system up and running, and still be up to date. Click this screenshot to head on over to Oracle Media Network to watch the video:

We'll see you next week!

  • Subscribe an Oracle Linux system to the Ksplice channel on Oracle's Unbreakable Linux Network (ULN)
  • Install the Ksplice uptrack software package using the yum utility
  • Use the Ksplice uptrack utility to install Ksplice kernel updates without any need to reboot
  • Use the Ksplice web interface

Friday Spotlight: New Oracle VM Templates for Oracle Database

Happy Friday!

In last week's Oracle Virtualization Spotlight, Honglin Su discussed new Oracle VM Templates for Oracle Database. Here's an excerpt:

The Oracle VM Templates for Oracle Database provides a framework that fully automates the creation of a Single Instance, Oracle Restart (Single Instance/HA) or Oracle Real Application Clusters (RAC) configurations in an Oracle VM environment. In a matter of minutes the versatile and powerful Oracle VM Templates for Oracle Database can be cloned into any number of VMs which could be deployed as a Single Instance, Oracle Restart (Single Instance/HA) or Oracle RAC of any number of nodes.

Of course, this is the Oracle Linux blog, so why am I referencing new Oracle VM Templates? Because these templates of course run Oracle Linux! Here are the highlights of the new templates:

NEW in 2015 Templates:

  • Yum@Deploy support(11gR2 & 12c) - Allows running yum install/update during first boot/deployment and subsequent re-builds.
  • Multi-Diskgroup support for Oracle ASM
  • Support for multiplexed Controlfile & REDO logfiles
  • Default kernel boot is Unbreakable Enterprise Kernel (UEK3) 3.8.13-55, seamless transition to HVM mode
  • Oracle Linux 7, BTRFS & Ksplice Ready!

You can read Honglin's full post over at the Oracle Virtualization Blog, or you can go directly to the Oracle VM Templates for Oracle Database page.

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

Friday Spotlight: Get The Story Straight From The Source

Happy Friday!

One of the great things about webcasts is that you get to hear directly from Oracle experts and even ask questions about your own environment. They are a great way to get in-depth information straight from the source, especially if you weren’t able to come out to Oracle OpenWorld this year.

Coming up next Tuesday, we have an excellent webcast hosted by Oracle Linux Product Management Director Avi Miller, “Spacewalk and Ksplice: Keep Oracle Linux Systems Up to Date and Secure.” In the webcast, Avi will explain the details on using Spacewalk and Ksplice with Oracle Linux. And you’ll be able to ask Avi questions through the chat interface. And since Avi is based in Australia, we’ve scheduled this webcast at 3PM PST, allowing our friends in that part of the world to be able to tune in at a reasonable hour.

And thank you to those of you that joined our webcast this past Tuesday on Building the Modern Cloud-Enabled Data Center! If you missed that one, it’s a great introduction to Linux Containers, Docker, OpenStack, and more. The replay is just over 20 minutes, so you can head on over and check it out for a very concise overview of these technologies:


Have a great week!

Friday Spotlight: Using Ksplice as a Diagnostic Tool with Oracle Support

Happy Friday! And for those of us in the US, happy Independence Day!

Our spotlight this week is on a new paper written by Oracle's Robert Chase (if you read the Oracle Linux articles over on Oracle Technical Network, you'll be familiar with his work). This paper focuses on the use of Oracle Ksplice -- well known as a kernel patching tool -- as a diagnostic tool to help you when working with Oracle Support. It's really a great use of the technology, have a read below:
