Troubleshooting Oracle Performance
What do you do when your database application isn’t running fast enough? You troubleshoot, of course. Finding the slow part of an application is often the easy part of the battle. It’s finding a solution that’s difficult. Troubleshooting Oracle Performance helps by providing a systematic approach to addressing the underlying causes of poor database application performance.
- Written for developers by an application developer who has learned by doing
- Gives a systematic approach to solving database application performance problems
- Helps you plan for performance as you would for any other application requirement
What youll learn
- See how to treat and plan for performance as a basic application requirement.
- Identify performance problems using a systematic and repeatable approach.
- Configure your query optimizer to meet your application performance goals.
- Optimize table accesses, joins, and physical table layout.
- Read and recognize inefficient SQL execution plans.
- Reduce inefficiencies from too much procedural code.

Most Thorough, Yet Compact Performance Tuning Book 9i-11g,
“Troubleshooting Oracle Performance” is the most thorough, yet physically compact book covering performance tuning with Oracle 9i R2 through 11g R1 on the market. It is quite clear that a great deal of effort was made by the author to carefully verify the tips and test results contained in the book and to organize the material in a logical progression, thus building a bridge between the reader’s current understanding to the understanding of complex tuning approaches.
What this book accomplishes, which most other performance tuning books seem to miss, is to indicate which performance tuning features are available in each Oracle release (and which are available at no additional licensing cost) as the various performance tuning approaches are discussed. Not only does the book indicate when a feature would be appropriate, but also potential problems (“Pitfalls and Fallacies”) associated with each feature.
The depth of coverage of Oracle 11g R1 features is surprisingly thorough given the short amount of time which that version has been on the market. A little more detail in a couple areas, such as hacking stored outlines, would have been helpful; at the same time, everyone who reads the book might have a different opinion of what needed additional detail, the book could have grown to 2500 or more pages, and likely would have been obsolete by the time it was published.
The Apress Roadmap on the back cover of the book indicates that this book should be read before “Forecasting Oracle Performance”, “Expert Oracle Database Architecture”, and “Cost-Based Oracle Fundamentals”. The “Troubleshooting Oracle Performance” book seems to assume that the Oracle database concepts are well understood. As such, it is probably wise to read “Expert Oracle Database Architecture” first, followed by this book, “Cost-Based Oracle Fundamentals”, and finally “Forecasting Oracle Performance”.

|A MUST for Developers and DBAs,
BOTH Developers and DBAs can learn from this book. Along the line of “Optimizing Oracle Performance” by Cary Milsap; this books shows by clear examples how to Identify Performance Problems (Chapter 3) and how to solve those problems (the remainder of the book).
Developers can learn how to Instrument code to help the tuning process.
DBAs can then trace the code and find the bottleneck/waits.
This book bridges the gap between Developers and DBAs and points out indirectly that Performance is a teams effort and solution.

|Excellent work,
This book is exremely useful for Oracle Administrators and Developers alike. It is easy to understand and contains valuable information for everybody interested in understanding Oracle performance issues. The author demonstrates an excellent method to identify wrong Optimizer estimates that lead to suboptimal execution plans.
The author shares dozens of “best-practices” and advices from his personal consulting experience as well es detailed information which is not available in Oracle documentation.
My personal highlight was the introduction to a sophisticated, yet easy-to-use SQL Trace Analyzer TVD$XTAT which overcomes the limits of tkprof for SQL Response Time Analysis.
This book is a must-have for every Oracle professional.
