Oracle Performance Tuning for 10gR2

by Gavin Powell

Tuning of SQL code is generally cheaper than changing the data model. Physical and configuration tuning involves a search for bottlenecks that often points to SQL code or data model issues. Building an appropriate data model and writing properly performing SQL code can give 100%+ performance improvement. Physical and configuration tuning often gives at most a 25% performance increase. Gavin Powell shows that the central theme of Oracle10gR2 Performance Tuning is denormalize data models to fit applications; tune SQL code according to both the data model and the application in relation to scalability; create a well-proportioned physical architecture at the time of initial Oracle installation; and most important, mix skill sets to obtain the best results.

About the author

Mike McCallister is devoted to the idea that technology need not be feared, and can be mastered by anyone. After all, he grew up in the days when computers filled entire rooms, and spent 13 years as a civil service clerk doing nothing more technical than recording WordPerfect macros.

He is devoted to making computing easier for the full spectrum of user levels and experience. As a technical writing consultant, freelance computer magazine writer, and book author, he understands that ordinary people can and should make the most of their tools.

Besides Linux and open source software, interests include tools for communicating via the Web (blogs, social networks, wikis, and the like) and bridging the digital divide.

McCallister has been running Linux as his primary day-to-day desktop operating system since 1999, but he also documents software for a variety of platforms as the Document Architect at PKWARE, Inc.

He writes a technology-oriented blog, Notes from the Metaverse. His technology stories have been published in places like:

LinuxJournal.com

LinuxWorld

Java Developer's Journal

SearchEnterpriseLinux.com

He is a compulsive joiner. Among the relevant groups: Senior Member of the Society for Technical Communication, and immediate past president of the Wisconsin chapter; Web414, Milwaukee's Web Community; and the National Writers Union, UAW Local 1981.

He absolutely loves going to BarCamps and BarCamp-style events, especially BarCampMilwaukee. Occasionally, you'll also find him at the Milwaukee Linux Users Group

When he's not staring at computer screens (which he admittedly finds strangely alluring), you'll often find him trying to make the world a better place. Or reading, watching a baseball game or other sporting event (live or on TV), hanging out with the grandkids and walking around urban landscapes. "
