Friday Spotlight: Oracle Linux and MySQL TPC-C Optimizations Whitepaper

Happy Friday Oracle Linux fans, this week our spotlight is a new whitepaper that is co- authored by Rick Stehno of Seagate and Avi Miller of Oracle. This paper gives tips to optimize your Oracle Linux, MySQL and the PCIe card which increases the performance of your environment with just few steps:

Oracle Linux and MySQL TPC-C Optimizations When Implementing the Sun Flash Accelerator F80 PCIe Card 

Oracle Linux with Unbreakable Enterprise Kernel (UEK) was chosen for this study because of its upstream support for the latest hardware relevant to modern data center operations. In addition, MySQL database workloads benefit from the platform’s deep integration with the solution stack, optimizations resulting from industry collaborations and enhancements in the Unbreakable Enterprise Kernel.

Oracle Linux with the Unbreakable Enteprise Kernel includes extensive performance and scalability improvements to the process scheduler, memory management, file systems, and the networking stack. It was tuned to perform better and faster on leading-edge x86 configurations that feature many CPU cores and large amounts of main memory, and optimized libraries and system calls help to improve performance for MySQL queries. Because of these optimizations and pervasive testing that occurs within Oracle, Oracle Linux is able to address large transaction capacities and scale well as the number of database users or the number of databases increases. This document will present tuning and processes that can be applied to increase TPC-C performance when using the Sun Flash Accelerator F80 PCIe Card.  

By following the simple tuning tips outlined in this paper, a successful implementation of the Sun Flash Accelerator F80 PCIe Card with optimal performance can occur in most environments.

Friday Spotlight: Using Ksplice as a Diagnostic Tool with Oracle Support

Happy Friday! And for those of us in the US, happy Independence Day!

Our spotlight this week is on a new paper written by Oracle's Robert Chase (if you read the Oracle Linux articles over on Oracle Technical Network, you'll be familiar with his work). This paper focuses on the use of Oracle Ksplice -- well known as a kernel patching tool -- as a diagnostic tool to help you when working with Oracle Support. It's really a great use of the technology, have a read below:

Friday Spotlight: Frequently Asked Questions about Oracle Linux

It is Friday and that means it is time for our Spotlight! 

Our spotlight today is the recently updated Oracle Linux FAQ. This is an excellent document that features some of the questions that everyone asks about Oracle Linux and Oracle Linux support. We cover variety of topics including general definitions, compatibility, support, pricing, indemnification, migration and many more.. 

Here's one of the questions as an example:

Q: What is DTrace for Oracle Linux?

A: DTrace is a comprehensive dynamic tracing framework that was initially developed for the Oracle Solaris operating system, and is now available to Oracle Linux customers. DTrace is designed to give operational insights that allow users to tune and troubleshoot the operating system. DTrace provides Oracle Linux developers with a tool to analyze performance, and increase observability into the systems they own to see how they work. DTrace enables higher quality applications development, reduced downtime, lower cost, and greater utilization of existing resources. It is available to download from ULN for Oracle Linux Support customers.

Have a great weekend!
