Book Review: Oracle PL/SQL Performance Tuning Tips & Techniques

“Oracle PL/SQL Performance Tuning Tips & Techniques” by Michael Rosenblum and Dr. Paul Dorsey is a book you should read soon. A quote from Oracle’s Bryn Llwellyn in the book’s forward says it all “Every professional PL/SQL programmer should study this book and act upon its teachings.”
Misha and Paul take the scientific route to performance, providing readers the how-and-why of effective performance. The first chapter sets the tone showing how performance is an aggregate typically of nine-steps from execution of code on the client side, through middleware, to server, and back again to the client. Learn how PL/SQL works from two of the best whose shared stories of actual issues underline the importance of performance planning and thinking.
Oracle database professionals rely upon PL/SQL to accomplish many important tasks. This book presents numerous opportunities to improve PL/SQL performance offering more than just code suggestions. Perhaps most importantly, each unit steps the reader through how to test and prove if an actual improvement has been made. Code examples include explanations of how to test results so that you know the impact of your actions. For each topic highlighted, the authors provide discussions of the tradeoffs being made; for instance, did CPU improve at the expense of I/O or vice-versa? Performance-related Oracle tools and instrumentation are explained and demonstrated clearly to illustrate and confirm results.
You can read this book straight through as I did, or, pick a specific topic like caching and skip around. However you choose to read this book you’re sure to learn lots about PL/SQL performance and how you can improve your systems.
