Friday Spotlight: Ksplice SNMP Plugin

Happy Friday!

Over at our Ksplice Blog (which has one of my favorite taglines, "Rebooting is Obsolete"), Oracle's Tim Hill writes about the new SNMP plug-in for Ksplice, which allows the use of Oracle Enterprise Manager or other SNMP-compatible monitoring solution to monitor Ksplice instances. It's very cool stuff, we hope you check it out.

We'll see you next week!

Friday Spotlight: Virtual Sysadmin Day Winter 2014

Happy Friday! Our Friday Spotlight today is a bit unique in that we're putting the same information on both the Oracle Virtualization blog and the Oracle Linux blog. The reason is that we want to tell you about a fantastic opportunity for Oracle VM and Oracle Linux administrators.

On January 28, Oracle is hosting an event called Virtual Sysadmin Day. If you haven't attended one of these before, you're in for a treat. These events let you attend a virtual version of the hands on lab sessions that we run each year at Oracle OpenWorld. So, if you've ever wanted to go to one of those sessions but couldn't get to San Francisco or the other Oracle OpenWorld locations around the world, now is your chance to attend from the comfort of you desk!

The format is really cool. The materials for the lab are provided for you, you just need to have Oracle VM VirtualBox (it's a free download), and download the pre-configured virtual machines for the labs. You should do this ahead of the event, but all the information to help you do it is available to you when you register.

On the day of the event, you login and watch some intro content that sets up the labs, and then you follow the steps for the labs on you own system. Oracle experts will be in the chat area to help with issues you might run into.

Virtual Sysadmin Day Winter 2014
January 28, 2014
9AM - 1PM Pacific Standard Time

Virtual Sysadmin Day is one of my favorite events, I hope you have time to check it out!

Oracle Linux Friday Spotlight - January 10, 2014

Happy Friday!

Our spotlight this week is on a great technical article over at Oracle Technology Network written by Oracle's Christopher Jones titled "How to Set Up DTrace to Detect PHP Scripting Problems on Oracle Linux."

The Unbreakable Enterprise Kernel release 3 (UEK) provides built-in support for DTrace. This can help you track down performance problems with your applications or scripts. In this article, Christopher walks through how to enable DTrace for the popular scripting language PHP on Oracle Linux and goes into some detail to how it works, including a simple D script to get information out of a sample PHP script.

This is a really fantastic article, so if you're interested in using DTrace to tune your PHP scrips, give it a read through.

We'll see you next week!

Oracle Linux: Free as in Speech AND Free as in Beer

One of the biggest benefits of Oracle Linux is that binaries, patches, errata, and source are always free. Even if you don’t have a support subscription, you can download and run exactly the same enterprise-grade distribution that is deployed in production by thousands of customers around the world. You can receive binaries and errata reliably and on schedule, and take advantage of the thousands of hours Oracle spends testing Oracle Linux every day. And, of course, Oracle Linux is completely compatible with Red Hat Enterprise Linux, so switching to Oracle Linux is easy.

CentOS is another Linux distribution that offers free binaries with Red Hat compatibility. Traditionally, CentOS has been used for Linux systems which do not require support in order to reduce or avoid expensive Red Hat Enterprise Linux subscription costs. Recently, Red Hat announced it was “joining forces” with the CentOS project, hiring many the key CentOS developers, and “building a new CentOS.” This is a curious development given that the primary factors that have made CentOS popular are that it is free and Red Hat compatible.

It would be natural for existing CentOS users to wonder what Red Hat actually has in mind for the “new CentOS” when the FAQ accompanying the announcement states that Red Hat does not recommend CentOS for production deployment, is not recommending mixed CentOS and Red Hat Enterprise Linux deployments, will not support JBoss and other products on CentOS, and is not including CentOS in Red Hat’s developer offerings designed to create “applications for deployment into production environments.”

If Red Hat truly wished to satisfy the key requirements of most CentOS users, they would take a much simpler step: they would make Red Hat Enterprise Linux binaries, patches, and errata available for free download – just like Oracle already does.

Fortunately, no matter what future CentOS faces in Red Hat’s hands, Oracle Linux offers all users a single distribution for development, testing, and deployment, for free or with a paid support subscription. Oracle does not require customers to buy a subscription for every server running Oracle Linux (or any server running Oracle Linux). If a customer wants to pay for support for production systems only, that’s the customer's choice. The Oracle model is simple, economical, and well suited to environments with rapidly changing needs.

Oracle is focused on providing what we have since day one – a fast, reliable Linux distribution that is completely compatible with Red Hat Enterprise Linux, coupled with enterprise class support, indemnity, and flexible support policies. If you are CentOS user, or a Red Hat user, why not download and try Oracle Linux today? You have nothing to lose – after all, it’s free!

Oracle Linux Friday Spotlight - December 6, 2013

Happy Friday!

By now, you've probably heard about the release of Oracle Linux 6.5. One really cool thing about this release is that Unbreakable Enterprise Kernel Release 3 is installed by default, meaning you get to use all the great features of UEK R3 without needing to do a separate installation. And are there a lot of great features in UEK R3! So, our spotlight this week is on the release notes for the latest version of Oracle's Unbreakable Enteprise Kernel.

Unbreakable Enterprise Kernel Release 3 release notes

You'll learn about Control Groups, Linux Containers, DTrace, additional crypto options, improved diagnostics, the updated btrfs, better memory management, more networking options, improvements for performance, security, storage, and much more.

See you next Friday!

Announcing Oracle Linux 6.5 including the Unbreakable Enterprise Kernel Release 3

We're happy to announce the immediate availability of Oracle Linux 6 Update 5, the fifth update release for Oracle Linux 6. You can find the individual RPM packages in our public yum repository now; ISO installation images will be freely available for download from the Oracle Software Delivery Cloud soon.

Some highlights in this release include:

  • DTrace support has now been integrated in the default kernel and now supports user-space tracing of DTrace-enabled applications via the USDT provider.
  • Linux Containers (LXC) are now supported in the UEK R3.
  • The Btrfs file system now supports the send and receive subcommands that allow you to record the differences between two subvolumes, which can either be snapshots of the same subvolume or parent and child subvolumes. Btrfs now also supports replacing devices without unmounting or otherwise disrupting access to the file system.
  • The OpenFabrics Enterprise Distribution (OFED) 2.0 stack has been added, supporting a wide range of Infiniband protocols.
  • Paravirtualization support has been enabled for Oracle Linux guests on Windows Server 2008 Hyper-V or Windows Server 2008 R2 Hyper-V.

For more details on these and other new features and changes in Oracle Linux 6 Update 5, please consult the Release Notes in the Oracle Linux Product Documentation Library.

Oracle Linux 6 Update 5 is the first Oracle Linux distribution that installs the Unbreakable Enterprise Kernel Release 3 (based on mainline Linux 3.8) by default on systems based on the x86_64 architecture. The UEK R3 has already been released and announced for previous Oracle Linux 6 versions via a dedicated yum repository in October. The Red Hat compatible kernel is also included for compatibility.

For a detailed list of notable changes and improvements in UEKR3, please check the Release Notes for Unbreakable Enterprise Kernel Release 3.

As usual, Oracle Linux can be downloaded, used and distributed free of charge and updates and errata are freely available. For support, you are free to decide which of your systems you want to obtain a support subscription for, and at what level each system should be supported. This makes Oracle Linux an ideal choice for your development, testing and production systems - you decide which support coverage is the best for each of your systems individually, while keeping all of them up-to-date and secure.

Read the press release.
