Friday Spotlight: Optimizing Oracle Database Performance on Oracle Linux with Flash

Happy Friday!

This week, I'm dipping into the archives for a really interesting white paper, "Optimizing Oracle Database Performance on Oracle Linux with Flash." It talks about one of my favorite benefits of running Oracle Linux or Oracle Solaris with Oracle database called Database Smart Flash Cache. From the summary of the paper:

"This document explains how to increase Oracle database performance and improve user response time by deploying Oracle’s Flash Accelerator hardware with Oracle’s Database Smart Flash Cache feature. Oracle’s Database Smart Flash Cache feature is supported only on Oracle Linux and Oracle Solaris operating systems beginning with Oracle 11gR2.

The benefits outlined here apply to all Oracle Flash products on Oracle Linux or Oracle Solaris. For this particular study Oracle’s PCIe based in-server Sun Flash Accelerator F40 PCIe Card and Oracle Linux with Unbreakable Enterprise Kernel were used. The findings apply to both the Sun Flash Accelerator F40 and F80 PCIe Cards."

You can read the full paper here.

I also wanted to give a reminder for our webcast next week on Docker. This is a fantastic opportunity to learn not only how to get your feet wet with Docker and Oracle Linux, but you'll also learn the sorts of use cases where Docker really shines from one of our top experts, Avi Miller.

Friday Spotlight: Get The Story Straight From The Source

Happy Friday!

One of the great things about webcasts is that you get to hear directly from Oracle experts and even ask questions about your own environment. They are a great way to get in-depth information straight from the source, especially if you weren’t able to come out to Oracle OpenWorld this year.

Coming up next Tuesday, we have an excellent webcast hosted by Oracle Linux Product Management Director Avi Miller, “Spacewalk and Ksplice: Keep Oracle Linux Systems Up to Date and Secure.” In the webcast, Avi will explain the details on using Spacewalk and Ksplice with Oracle Linux. And you’ll be able to ask Avi questions through the chat interface. And since Avi is based in Australia, we’ve scheduled this webcast at 3PM PST, allowing our friends in that part of the world to be able to tune in at a reasonable hour.

And thank you to those of you that joined our webcast this past Tuesday on Building the Modern Cloud-Enabled Data Center! If you missed that one, it’s a great introduction to Linux Containers, Docker, OpenStack, and more. The replay is just over 20 minutes, so you can head on over and check it out for a very concise overview of these technologies:


Have a great week!

Oracle Linux images for Docker released

The Oracle Linux team is pleased to announce an update to Docker on Oracle Linux, along with the release of official Docker images for Oracle Linux 6 and 7. With this update, customers will have access to the tools needed to create, manage and deploy Docker containers on Oracle Linux.

The Docker Engine and Official Oracle Linux images are fully supported as part of Oracle Linux Basic and Premier support subscriptions. The scope of Oracle Linux support for Docker can be found in My Oracle Support, Document ID 1921163.1.

Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. Consisting of Docker Engine, a portable, lightweight runtime and packaging tool, and Docker Hub, a cloud service for sharing applications and automating workflows, Docker enables apps to be quickly assembled from components and eliminates the friction between development, QA, and production environments. As a result, IT can ship faster and run the same app, unchanged, on laptops, data center VMs, and any cloud.

You can learn more about using Docker on Oracle Linux in the Oracle Linux Administrator's Solutions Guide for Oracle Linux 6 and the Oracle Linux Administrator's Guide for Oracle Linux 7.

You can install Docker for Oracle Linux from the Add-ons Channel for Oracle Linux 6 and 7, either via the Unbreakable Linux Network or the Oracle Public Yum Server

You can browse the available Docker Images on the Oracle Public Yum Server at http://public-yum.oracle.com/docker-images/

Happy Friday!

If you're heading to the beautiful city of Seattle for USENIX LISA14 next week, you'll have a great opportunity to get your questions answered about Oracle Linux, Oracle VM, and Oracle OpenStack for Oracle Linux.

Oracle has three main things going on at the show:

- On Wednesday November 12, Oracle is sponsoring the Expo Happy Hour, from 5:30pm to 6:30pm. You'll be able to enjoy some beverages and chat with your peers (and Oracle folks, too!) in a relaxed environment.

- On Thursday November 13 from 11:45am to 12:30pm, join Oracle's Ken Crandall for "Building the Modern Cloud-Enabled Data Center with Oracle Linux", in Redwood AB.

 - And on both Wednesday and Thursday, Oracle experts will be at booth #308 to talk to you about your environment and how Oracle can help.

It should be a great show and we're looking forward to meeting some of you there!
