If you like YAPP, just get it! 11 janvier 2005
Par Amazon Customer - Publié sur Amazon.com
Format: Broché
if you're into the whole wait event thang, get this book. This is a great resource. Very interesting reading! Chapter 4 presents an event data collector (page 86: Sampling for performance data using pl/sql procedure), a very nice idea. The logoff trigger discussed in the same chapter is nice too. Chapter 5 gives a good overview of some of the most important I/O related wait events. Chapter 6, Locks and latches. Chapter 7, latency related wait events. And then there's tons more, look inside the book and see what I mean...
All in all, this is one of the best Oracle books of the past six months. My other favorite would be 'Oracle Insights' from Oaktable press.

I've implemented the data collector mentioned inchapter 4 to diagnose some performance problems. If you're interested, you can download the code for free from my website, www rhdba dot com. Look under Oracle SQL Scripts -> Event data collector.

Other must have books:
- Tom Kyte's 'Expert one-on-one' and 'Effective Oracle by Design'
- Cary Millsap and Jeff Holt 'Optimizing Oracle Performance'
- Oaktable press 'Oracle Insights'

Authoratative landmark work on Oracle internals 23 octobre 2004
Par Tim Gorman - Publié sur Amazon.com
Format: Broché
The book is simply spectacular, both for the quality of its writing as well as the depth of the material. Practical? Indeed, indispensible!

The three authors, Richmond Shee, Kirti Deshpande, and K Gopalakrishnan, have done a wonderful job in organizing a enormous subject area into manageable chunks. They have also managed to render potentially bone-dry source material into very readable text, interspersed heavily with code examples and output, sidebars, and analogies. This is a good read as well as an authoritative reference. I'm still unable to read it steadily for long periods of time, as the analogy of trying to drink from a fire-hose is relevant here. But picking it up and reading different sections, treating it like a reference, has proved rewarding. Richmond, Kirti, and K had an absolute "dream team" of reviewers on this book in Kyle Hailey, John Kanagaraj, Craig Shallahamer, and Graham Wood. The combined efforts of the three authors and the four technical editors blows my mind.

All I can say is - get it! You may (like me) not read it immediately. But, keep it handy. Along with the Google, Ixora, Asktom, JLComp, MetaLink websites, this book is the place to find explanation for the unexplainable in Oracle. Start skimming through it and recognize situations that had previously baffled now being explained (and proved) in full. It is like a light coming on.

Great book 3 septembre 2004
Par Angela Simmons - Publié sur Amazon.com
Format: Broché
I recently attended a local OUG Meeting in which Richmond gave a presentation on the efficient use of the Oracle Wait Interface to diagnose and solve performance problems. His presentation and philosopy corroborated another source that I had read "Performance Tuning 101" Unfortunately, I didn't win one of the three copies that he was giving away at the meeting. Instead, I went straight back to the office to order this book. It is everything I expected and more. I particularly appreciate chapter 4 in which the authors provide step by step instruction on how to create your own tool for monitoring and collecting wait interface data. I just implemented this new tool in a production environment and have already been able to diagnose some potential application "issues". This book rocks.

OWI explained as it should be 22 novembre 2004
Par N. PINTO-DO-SOUTO - Publié sur Amazon.com
Format: Broché
A lot of people have been talking about monitoring and tuning using the "wait interface". There are too many sites around with bits and pieces of the necessary information, but up until now there wasn't a complete source on the subject.

Having used Oracle since 1984, I have read just about every advanced book on Oracle databases. This one is right at the top of the list for anyone wanting to learn how to accurately monitor and tune Oracle databases.

Here at last is a single, complete and authoritative reference for all to use. And what I like the best: it is not restricted to a single version of Oracle. Simply the best reference right now.

OWI Gold Mine !! 5 juin 2006
Par Vinod Haval - Publié sur Amazon.com
Format: Broché
An excellent read, I have to say that it exceeds my expectations. For those who are just getting exposed to the myths of OWI, a must read from cover to cover.

Having worked in Performance Tuning for the last few years I never come across a book which is complete in itself and needs no additional reference to other books or documents.

The authors of this book have done an excellent job in exposing invaluable information on Oracle wait Interface. Particularly, they targeted the most important waits that one must pay attention to while dealing with Oracle performance issues. On the contrary to misconceptions floating around usage of x$ which was thought to hamper performance the author clearly demonstrates its use throughout the book.

This is one of a kind book available. A book like this should be part of all serious DBAs reference collection. More importantly one of the very very few books that helps not only identifying the problem but actually offers a solution for the same....provides a cause for the event and ways to alleviate it.

Kudos to the authors for writing such a wonderful book and would highly recommend it for anybody wanting to plunge into the OWI gold mine.

Fantastic work
