If you already have Oracle VM VirtualBox installed, Vagrant boxes make for really quick way to get Oracle Linux up and running on your development machine. We've just updated our Oracle Linux 6 Update 9 and Oracle Linux 7 Update 4 here: yum.oracle.com/boxes Both have the latest Unbreakable Enterprise Kernel release 4 (4.1.12-103.3.8.1) and are pre-configured with yum repositories enabled to install the latest of our builds of cx_Oracle, ruby-oci8, td-agent, terraform*,...

Note: When I first wrote this post, we had just released cx_Oracle packages using a different naming scheme. In this revision dated 7 Feb. 2018 I use the new, correct naming conventions. The following RPMs will no longer be updated: cx_Oracle-12c-py26.x86_64 5.3-1.el6 ol6_developer cx_Oracle-12c-py35-scl.x86_64 5.3-1.el6 ol6_developer cx_Oracle-py26.x86_64 6.0.2-1.el6 ol6_developer cx_Oracle-py35-scl.x86_64 ...

Oracle Linux is what powers our Engineered Systems and Oracle Cloud. So when you run Oracle Linux, you benefit from our extensive testing. But did you know that subscriptions for Oracle Cloud Infrastructure (OCI) include Oracle Linux Premier Support at no extra charge?

Running applications on Red Hat Enterprise LinuxT...

This post is a quick reminder that Oracle Linux includes a handy RPM to address pre-installation requirement for Oracle Database 12c.  Starting with Oracle Database 12c Release 2, we changed the name for this RPM, so the RPM you should look for depends on what release of Oracle Database 12c you plan to install: For Oracle Database 12c Release 2: oracle-database-server-12cR2-preinstall For Oracle Database 12c Release 1: oracle-rdbms-server-12cR1-preinstal Both of these RPMs are...

This post was updated on June 5, 2019 to include use of Vagrant builds published on GitHubOK, not completely zero, but pretty close! If you have Oracle VM VirtualBox and Vagrant installed and would like to take Docker for a spin on Oracle Linux, you should try this. Our most recent Oracle Linux 7 Update 6 Vagrant box makes a good starting point to set up and configure Docker. It includes: Unbreakable Enterprise Kernel 5 with support for Docker and Btrfs A spare virtual disk...

Every so often security bugs are found that are significant enough to get rewarded with a proper name. Sometimes even a whole web site. Remember Dirty Cow? Heartbleed? Recently a kernel bug colloquially called Stack Clash (CVE-2017-1000364) was discoveredthat can result in a local privilege escalation by overwhelming memory protections put in place to prevent programs from accessing memory they are not supposed to. The bug affects Linux Kernel versions 4.11.5 and earlier and...

Vagrant is a tool to manage virtual machine-based environments. Read more about Vagrant here. Why use Vagrant? If you develop code that runs on Linux but use a MacOS or Windows machine to run your preferred browser, editor, debugger or development tools, Vagrant offers a consistent workflow to create disposable Linux environment whose configuration and dependencies are isolated from your development machine. Vagrant Boxes are pre-built base images that can be imported into...

The installation media ISO for Oracle Linux 6.3 is still "in the oven" but the RPMs are already available.  You can grab them on ULN, if you have an Oracle Linux support subscription, or anyone can get them from the Oracle Linux yum server.  Oracle Linux 6.3 includes a quarterly update of Unbreakable Enterprise Kernel Release 2 (kernel-uek-2.6.39-200.9.0.el6uek).  To install that kernel, make sure you have the ol6_UEK_latest channel or repo enabled.  Enjoy.
