Oracle Linux and Oracle VM pre-validated, pre-tested with FlexPod

As the Oracle community is gathering at IOUG this week sharing news, checking out the latest innovations, the Oracle VM and Oracle Linux team are also busy working to expand our platform validation support. In a collaborative effort with both Cisco and NetApp, we’d like to give you an early glimpse of the upcoming reference architectures for Oracle Linux and Oracle VM with FlexPod:

  • A FlexPod with Oracle VM is scheduled for the second half of 2013  – this Oracle VM architecture offers virtualization coverage for Oracle as well as non-Oracle workloads
  • A FlexPod featuring NetApp Clustered Data ONTAP with Oracle Linux,  coming Jun 30, 2013 – this is the second Oracle Linux bare-metal design
  • A FlexPod with Oracle Linux, coming June 14, 2013 – this is one of two bare metal designs for running Oracle DB on Oracle Linux
The combined products give customers access to infrastructure designs that are pre-tested and pre-validated building blocks for application consolidation, private cloud migration or data center modernization.
In addition to the benefits of the integrated design and validation, there are specific unique benefits that Oracle VM and Oracle Linux add to FlexPod:
  • Oracle VM – Application-Driven Virtualization difference: Speed Dev/Test/Production application deployment – Using Oracle VM Templates, customers can deploy applications 7-10x faster than traditional virtualization approaches. Entire application stacks including guest OS with Oracle Linux can quickly be deployed or provisioned in hours or minutes. This empowers IT to have a direct impact on the business Quality of Service by enabling more test systems and or respond to end customer requirements more quickly.
  • Enhanced high availability with Oracle Linux: With Ksplice, Oracle Linux kernel updates are installed in seconds, without interrupting running applications or the people using those applications. You can quickly check on the current status of your systems before rolling out updates to your network. Installing updates requires no downtime, so your systems are more available than ever.
  • Certified by Oracle: All Oracle applications are certified on Oracle VM. This gives customers peace of mind that FlexPod with Oracle VM running Oracle applications are both fully tested and  certified by Oracle
  • Reduce Licensing Cost: with zero licensing cost for both Oracle VM and Oracle Linux and low enterprise support cost, customers can dramatically reduce both capex and opex IT spending. 
We’ll keep you updated as these reference architectures get published. Like us on Facebook or Follow us on Twitter to stay informed.

Announcing Ksplice Inspector!

Everyone knows a good inspector is crucial when buying a home or looking for clues in a "whodunit". And now you also have an "inspector" for your Linux kernel!

Today Oracle released a new tool called the Ksplice Inspector enabling Linux users to analyze kernel updates available for their Linux kernel. With so many kernel updates released, it can be difficult to keep track. At Oracle, we monitor kernels on a daily basis and provide bug and security updates administrators can apply without a system reboot. To help out, the Ksplice team at Oracle has produced the Ksplice Inspector, a web tool to show you the updates Ksplice can apply to your kernel with zero downtime.

Read the Ksplice blog article for more details on this new tool and who can use it.

Updating and patching Oracle Linux using yum and Ksplice

Oracle Linux provides two complimentary technologies for patching and updating the operating system.

yum for updating RPM packages. Applications and libraries are packaged and distributed in the form of RPM packages, which are collected in yum repositories. Updates are installed by downloading the packages from the yum repository and installing them locally using the RPM package manager.

It's probably worth repeating that Oracle also provides updates (errata) for free from our public-yum server - you can keep your system up to date and fully patched against security threats without the need of purchasing a support subscription. This makes Oracle Linux and ideal choice to install on both your development and production systems - it is up to you to individually choose which of these systems you want to have covered by a support subscription and at which level.

We also provide updates to the Linux operating system kernel in RPM format. However, these changes only take effect after the system has been rebooted, which can be quite disruptive in certain environments. Scheduling downtime for a reboot is never easy.

This is where Ksplice enters the picture. It is a technology that allows you to apply critical fixes to the Linux kernel at run time, without the need to reboot your system. This is a feature that is unique to Oracle Linux. The system connects to the Ksplice server to obtain the individual rebootless patches, split up by security issues (which are usually tracked by CVE numbers). You can install all of the patches in one go, or choose to install only selected patches, without any service interruption or downtime. Ksplice patches can also be removed at run-time, in case they show any any unwanted or unexpected side-effects.

Both yum and ksplice require downloading patches from a remote server, so the client system needs to be able to connect to a remote server. In many cases, connecting to an update server located on the public Internet directly is not an option, due to security policies.

In the case of yum, it's possible to create a local copy of a repository and simply point all clients to obtain their patches from there instead. There are several ways to create and manage such local repositories, and Oracle Enterprise Manager 12c Cloud Control and Ops Center both provide built-in functionality to support this. We also published a script on OTN that automates the task of downloading RPM packages from the Unbreakable Linux Network.

For Ksplice, it was already possible to set up a local server that would act as a caching proxy server for all available patches - the client systems would only have to connect to this server instead of contacting the remote Ksplice server over the Internet directly. However, this solution requires setting up a dedicated system just for this particular task, so many customers were not too happy about this solution.

The Ksplice team at Oracle now came up with an alternative solution - instead of providing the Ksplice patches as individual downloadable items, they are bundled inside an RPM package, one for each Linux kernel version we support. Any time a new ksplice patch is available, the respective RPM package will be refreshed. This way we can now deliver Ksplice patches via yum repositories, which is a well-established transport mechanism and can utilize already existing infrastructure. The process involves two steps: first you download the ksplice patch RPM using yum, then you run the local ksplice client, which has been modified to check for updates on the local file system instead of contacting the remote server. Even though you are using RPM to download the Ksplice patch bundle RPM, you still use the local ksplice client to apply the individual patches at run time.

This new Ksplice offline mode gives you the best of both worlds: being able to patch your Linux kernel at run-time without disrupting any services, while not requiring you to manage any additional infrastructure or services, or having to negotiate any exceptions to your firewall rules in order to allow your systems to contact the remote Ksplice server.

For more information about the Ksplice offline mode, please see Wim's blog post or check out the following video, which outlines the basic principles of how to apply updates to your Oracle Linux system:

Monday Jan 07, 2013

Introducing the Ksplice Offline client

We are excited to announce the availability of a new feature in our Ksplice service, known as the Ksplice offline client.  This new option eliminates the requirement on a direct connection to the internet to apply zero-downtime Ksplice patches.  The Ksplice offline client allows the user to create a local YUM repository which will mirror the Ksplice channel from ULN (Unbreakable Linux Network).  Once you have mirrored the channel on your local network, you simply apply the patch using the same Ksplice tools and commands you are already familiar with.  Ksplice is available to all customers with Oracle Linux Premier or Oracle Linux Premier Limited support.  Take a look at Wim's blog, where he provides an excellent example for how to setup and use this new service and if you are using Red Hat and want to try Ksplice, you can sign up for a 30 Day Free trial

Did You Hear About RedPatch?

With today’s RedPatch announcement, the Oracle Linux team provides the Linux community a repository containing the source for all the changes Red Hat makes to their kernel, free of charge, available from our public git site. This repository simplifies life for administrators by providing them a straightforward method for determining the type of fixes a patch contains.

Rebootless updates: now available for Red Hat Enterprise Linux, too!

As you probably know by now, we in the Oracle Linux Team are quite enthusiastic about Ksplice. Just in case you haven't heard about Ksplice yet, this technology allows you to apply security fixes and upgrades to the Linux kernel while your system is running, without having to reboot your server. Your applications remain unaffected — there is no service disruption or performance impact involved.

Ksplice was added to our Oracle Linux Premier support subscription some time ago (at no additional cost) and customers rely on it to ensure their systems are always up to date and fully patched, even if the next scheduled maintenance window is still days (or weeks) ahead.

Before, Ksplice patches were only provided for customers running Oracle Linux with the Unbreakable Enterprise Kernel. Today, we’re extending our support offering: Ksplice zero downtime kernel updates are now available for the Red Hat compatible kernel on Oracle Linux 5 and 6 as well. And if you are running Red Hat Enterprise Linux without Oracle Linux support and you’d like to try Ksplice, sign up for our 30-day free trial.  

In addition to that, we will continue to provide Ksplice patches for Fedora and Ubuntu Linux for free. If you want to learn more about Ksplice, check out Wim's OTN article "Using Oracle Ksplice to Update Oracle Linux Systems Without Rebooting" and Waseem's Ksplice Demo Video on the Oracle Linux YouTube Channel.
