Beta 1 of Unbreakable Enterprise Kernel Release 3 now available

We are happy to announce the availability of Beta 1of the Unbreakable Enterprise Kernel Release 3 for Oracle Linux 6. The Unbreakable Enterprise Kernel Release 3 (UEK R3) is Oracle's third major release of its heavily tested and optimized operating system kernel for Oracle Linux 6 on the x86_64 architecture. It is based on the mainline Linux version 3.8.13.

The 3.8.13-13 release also updates device drivers and includes bug and security fixes. Some notable improvements in functionality and new features include:

  • Numerous stability and scalability enhancements
  • Inclusion of DTrace 0.4 for Linux into the kernel (no longer a separate kernel image). DTrace for Linux now now supports probes for user-space statically defined tracing (USDT) in programs that have been modified to include embedded static probe points.
  • Btrfs file system improvements (subvolume-aware quota groups, cross-subvolume reflinks, btrfs send/receive to transfer file system snapshots or incremental differences, file hole punching, hot-replacing of failed disk devices)
  • Improved support for Control Groups (cgroups) and Linux containers (LXC).
  • The ext4 file system can now store the content of a small file inside the inode (inline_data).
  • TCP fast open (TFO) can speed up the opening of successive TCP connections between two endpoints.

The Unbreakable Enterprise Kernel Release 3 can be installed on Oracle Linux 6 Update 4 or newer, running either the Red Hat compatible kernel or a previous version of the Unbreakable Enterprise Kernel. The UEKR3 beta kernel packages and supporting userland utilities can be installed using the yum package management tool from the public-yum server.

For installation instructions and more details on the new features, changes and any known issues, please consult the Release Notes found on our public beta site.

We've created a dedicated public beta test discussion forum — please join us and share your observations and impressions there!

Oracle Linux at Oracle Openworld 2013 - Update #2

We have 4 weeks left until Oracle Openworld San Francisco. In our first blog update, we covered Oracle Linux sessions. This is our second update in which we are covering Hand-on Labs and Demopods, where you can experience Oracle Linux at a personal level,  wheather you are a practical person that likes to play around with the software or a person interested in getting detailed insights from Oracle Linux kernel engineers and product managers, these are the places to visit and sessions to attend:

This year we have 2 Demopods and 2 Hands-On Labs:

Oracle Linux Demopods are located in Moscone South, Oracle Systems and Storage Demo grounds, Booth #1133

3533 - Oracle Linux: The Best Enterprise Linux

Oracle Linux brings the latest Linux innovations to market, delivering extreme performance, advanced scalability, and reliability for enterprise applications and systems along with worldwide, enterprise-class, cost-effective support. It is free to download and distribute, including patches and updates. Meet Oracle Linux experts and find out what makes Oracle Linux the best enterprise Linux. Learn about innovative features such as Ksplice zero-downtime updates, DTrace, and industry leading management and high availability tools available to Oracle Linux customers.

3537 - Migration Made Easy: From Red Hat and SUSE Linux to Oracle Linux

Thousands of customers rely on Oracle Linux to run their business-critical applications and lower their infrastructure costs. Oracle Linux offers many key advantages over both Red Hat Enterprise Linux (RHEL) SUSE Linux Enterprise Server (SLES). Visit this demo pod and discover the benefits of Oracle Linux compared to RHEL and SLES. Also learn how easy it is to migrate to Oracle Linux. Our experts will walk you through the migration steps and show you that the switch from RHEL to Oracle Linux support can be accomplished in just a few minutes.

Hands-On Labs

Getting Started with Linux Containers on Oracle Linux  (HOL10019)

Linux Containers (LXC) allow you to run multiple isolated Linux instances (containers) on the same host. A container is a way to isolate a group of processes from the others on a running Linux system that does not require you to set up a virtual machine on an emulation of physical hardware. This hands-on session gives you the basics of working with LXC on Oracle Linux; installing and configuring required software packages; setting up a Btrfs volume for the container storage; configuring, starting, and logging in to a container; changing a container's network configuration; limiting a container's resource usage (network/disk I/O); cloning an existing container; and monitoring and shutting down containers.

Oracle Linux Package and Patch Management Solutions (HOL10147)

In this session, you will learn how to implement and work with various patch management features of Oracle Linux. This includes working with the yum package manager and getting hands-on experience in obtaining more information on security errata using the security plug-in. The yum snapshot plug-in and the Btrfs file system are used to demonstrate how you can roll back package updates to a previous state. The session also covers creating a local yum repository and how to connect this repository to Oracle Enterprise Manager. In addition, you will learn about the Ksplice service and have the opportunity to install and configure the Ksplice offline client for applying kernel updates to your system with zero downtime.

Visit our demopod to receive a Oracle Linux and Oracle VM DVD Kit and other goodies.  You can plan your visit in the Openworld Schedule Builder and also bookmark Focus on Linux website to see when Oracle Linux events are happening.

We look forward to seeing you in Moscone South demogrounds and hands-on labs.

Till next time...

Oracle Enterprise Manager 12cR1 Agent Preinstall RPM for Oracle Linux 6 has been released

The Oracle Enterprise Manager Agent Preinstall RPM installs the required software packages and prepares the operating system for Oracle Enterprise Manager Agent deployment. It has recently been made available for both x86_64 and i386 platforms from the ol6_addons repository on the public-yum server and the Unbreakable Linux Network.

The Oracle Management Agent (Management Agent) is one of the core components of Enterprise Manager Cloud Control that is deployed on each monitored host. It is responsible for managing and maintaining the hosts and its targets and communicating that information to the middle-tier Oracle Management Service. The Management Agent also allows you to monitor non-Oracle components (such as third-party databases) through management plug-ins and connectors.

Once the Oracle Enterprise Manager agent is deployed on an operating system, the operating system and applications running on that host can be monitored and manged using the Oracle Enterprise Manager 12c console.

The Oracle Enterprise Manager Agent Preinstall package installs the required software packages and sets system parameters necessary to deploy and run the Oracle Enterprise Manager Agent on Oracle Linux 6. In particular, it performs the following tasks to enable the agent deployment:

  • Installs the required packages like sudo or openssh (via RPM package dependencies which will be resolved by the yum package manager)
  • Creates and configures the oracle user and group accounts
  • Modifies the user hard and soft file limits set in /etc/security/limits.d/
  • Installs sudo configuration templates

This RPM may be installed on an existing physical or virtual Oracle Linux 6 system, or may be included in an Oracle VM Template or Oracle Virtual Assembly. Note that the actual agent installation requires 2 GB of free space and 512 MB swap space, and therefore the system image should be configured to meet these requirements.

A. Installing on physical or virtual Linux machine

  1. Subscribe the system to the Oracle Linux 6 Addons channel in ULN (ol6_addons on public-yum).
  2. Install the RPM via yum:
    yum install oracle-em-agent-12cR1-preinstall
  3. Check that there is at least 2 GB free disk space in the agent install location (e.g. by using "df -h") and at least 512 MB of swap space (e.g. by running "swapon -s")

B. Including the RPM in the system.img disk image inside of an Oracle Virtual Assembly

  1. Place System.img and vm.cfg in the same folder
  2. As the root user, run the following command:
    # modifyjeos -f System.img -a <addrpm.lst> -m <rpm_directory_for_the_os>
    (where addrpm.lst contains the list of additional RPMs to install)
  3. Check if the root partition has a minimum of 2 GB of free disk space. If not, use the following command to increase the free space:
    # modifyjeos -f System.img -T <total new amount of disk space in MB>
  4. Check if there is a minimum of 512 MB of swap space. If not, use the following command to increase the swap space;
    # modifyjeos -f System.img -S <total new amount of swap space in MB>

An Oracle Enterprise Manager installation can be configured such that the Enterprise Manager agent is pushed on the Guest VMs automatically when the Oracle Virtual Assembly is deployed.

To configure the Oracle Management Server (OMS) for automatic agent push, update the following properties in the <OMS_HOME>/sysman/prov/agentpush/agentpush.properties file:

oracle.sysman.prov.agentpush.defaultPdpSetting=/bin/su - %RUNAS% -c "%COMMAND%"
oracle.sysman.prov.agentpush.enablePty=true
