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.
Not a good book for beginners.
Misha and Dr Dorsey follow a very effective pattern in this manual Each topic is introduced and all of the options are laid out, then they illustrate the performance impacts of those varfious options They share the code for each example so that we can use to prove the performance differences for ourselves to our peers.
The discussion and analysis is not a simple do it this way or your performance will really suck but is generously supported by their own experiences You couldn t ask for two experienced authors.
The book covers provides historical perspectives on a number of their approaches For instance, limitations in earlier releases affect many of our assumptions about performance tuning They point out where the old practices prejudices came from and roll it forward to the functionality available in today s 11g and 12c releases.
DBAs will benefit from the insights here, par This relatively thin book had been sitting on my desk unread, taunting me since it arrived this summer Now the leaves have turned, the book has been read, and I can move it to my bookshelf as it certainly deserves a spot next to my collection of Steven Feuerstein s classic PL SQL works Let s start with what Oracle PL SQL Performance Tuning Tips Techniques is not This book is not a step by step primer on how to tune PL SQL It does not provide a guide for analyzing trace output and diagnosing the cause of wait events in the database Instead, authors Rosenblum and Dorsey start by describing the many vectors by which performance problems can arise in modern multi tiered architectures They then describe tools and techniques that can be applied to instrument code and measure performance Once this groundwork has been laid, they proc
