We have an awesome new Oracle Infrastructure blog where we will be covering the Oracle Infrastructure products like, servers, engineered systems, OSes, storage and more. Subscribe to get the latest updates and news.
"When I talk to Linux administrators about the one thing they hate doing, it has to be patching.
Certainly one of the reasons is finding a time to take a system down to patch is next to impossible. That usually means having to miss your kid’s soccer game, your favorite sports team’s match on TV, or a rare night out with friends. And just how do you find time when you’re running systems in the cloud?
That’s why Oracle KSplice is such a game-changer—it allows for zero-downtime kernel updates. And that’s not even the whole story about Oracle Linux, with support for Docker, Linux Containers, OpenStack, Oracle Clusterware for High Availability (HA), and more—at no additional charge with an Oracle Linux Premier Support contract. In addition to the Red Hat Compatible Kernel (RHCK), Oracle supplies the optimized Unbreakable Enterprise Kernel (UEK), which was first developed to support highly scalable Oracle Engineered Systems. ..."
Oracle Technology Network welcomes you to join the Virtual Technology Summit from where you are- you don't need to travel. Attend this online event to watch technical demos and participate in hands-on-labs delivered by Oracle product experts, Oracle ACE’s, and Java Champions. Choose your technology track below for the full agenda, abstracts, and HOL participation instructions.
Database: The database track provides latest updates and in-depth topics covering Oracle Database 12c Advanced Options, new generation application development with JSON, Node.js and Oracle Database Cloud, as well as sessions dedicated to the most recent capabilities of Oracle MySQL for Oracle DBAs and Developers.
Java: In this track, we will show you improvements to the Java platform and APIs. You’ll also learn how the Java language enables you to develop innovative applications using Microservices, parallel programming, integrate with other languages and tools, as well as insight for the APIs that will substantially boost your productivity.
Middleware: The middleware track offers developers focused on gaining new skills and expertise in emerging technology areas such as Internet of Thing (IoT), Mobile and PaaS. This track also provides latest updates on Oracle WebLogic 12.2.1.and Java EE.
Systems: Designed for System Administrators this track covers best practices for implementing, optimizing, and securing your operating system, management tools, and hardware. In addition, we will also discuss best practices for Storage, SPARC, and Software Development.
Note that Docker 1.8 is only supported with the Unbreakable Enterprise Kernel Release 3 on Oracle Linux 6. The Red Hat Compatible Kernel is not supported.
There is no automatic upgrade from the previous Docker 1.6.1 release, as the package name has changed in this release. Containers created with the previous version will continue to work with Docker 1.8.
Please review the Oracle Linux documentation for upgrade instructions:
This year Australian Oracle User Group event INSYNC13 will feature Oracle Linux Half day workshop / Lab.
Come to see, hear and touch Oracle Linux – forget what others might have told you, experience it for yourself. How to install it, patch it and manage it and what is can do that no other Linux distributions can do. This is lab lecture session with ample time to experience Oracle Linux first hand plus a great Overview of Oracle Enterprise manager and Oracle VM for x86.
Being held in conjunction with the INSYNC13 series of conferences but being a separate component this workshop will attract an additional fee if you have not registered to attend one of the conferences.
Melbourne, 20 August 1.45pm - 4.30pm
Rydges on Swanston 701 Swanston Street, Carlton, Melbourne, VIC 3053
Registering only for the Linux lab will not provide entry to any other INSYNC13 Conference session. However, even though you have registered for the Conference, you are still required to register separately for this lab to ensure there are sufficient training materials available.

Now that the certification of the Oracle Database 11g R2 with Oracle Linux 6 and the Unbreakable Enterprise Kernel has been announced, we are glad to announce the availability of oracle-rdbms-server-11gR2-preinstall, the Oracle RDBMS Server 11gR2 Pre-install RPM package (formerly known as oracle-validated). Designed specifically for Oracle Linux 6, this RPM aids in the installation of the Oracle Database.
In order to install the Oracle Database 11g R2 on Oracle Linux 6, your system needs to meet a few prerequisites, as outlined in the Linux Installation Guides. Using the Oracle RDBMS Server 11gR2 Pre-install RPM, you can complete most of the pre-installation configuration tasks. which is now available from the Unbreakable Linux Network, or via the Oracle public yum repository.
The pre-install package is available for x86_64 only. Specifically, the package:
Causes the download and installation of various software packages and specific versions needed for database installation, with package dependencies resolved via yum
Creates the user oracle and the groups oinstall and dba, which are the defaults used during database installation
Modifies kernel parameters in /etc/sysctl.conf to change settings for shared memory, semaphores, the maximum number of file descriptors, and so on
Sets hard and soft shell resource limits in /etc/security/limits.conf, such as the number of open files, the number of processes, and stack size to the minimum required based on the Oracle Database 11g Release 2 Server installation requirements
Sets numa=off in the kernel boot parameters for x86_64 machines
In this article, Ginny explains how to use the Linux kernel's built-in resource control mechanisms (called "Cgroups") to manage the allocation of CPUs and memory to processes and how to configure disk I/O throttling for certain groups of processes. Cgroups is a very powerful and flexible feature of the Linux kernel. We hope you will find this article useful!
Btrfs ("Butter FS") is a new copy on write filesystem for Linux aimed at implementing advanced features while focusing on fault tolerance, repair and easy administration. Initially developed by Oracle, Btrfs is licensed under the GPL and open for contribution from anyone.
