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.
