SQL Wait Stats Joes 2 Pros (Paperback) Price: Rs.164

When you see the word ?I? followed by a business or client example, it will be a first person experience account from author Pinal Dave during his vast experience consulting in the field. Some of the experiences of Rick Morelan will be added as concepts. Bear in mind that the study of wait types is a vast subject, and it would be difficult for one person to understand every wait type and its associated statistics. SQL Server 2008 R2 includes nearly 500 wait types, and this number will increase in the next version of SQL Server (codename ?Denali?).

Wait types are not new to SQL Server but the techniques to interpret this feature are not widely available. Performance tuning has been a mainstream concern for SQL professionals for many years. There are many tactics which experts use to tune servers, queries, and systems; however, techniques for using wait types, wait queues, and wait statistics in performance tuning are understood by relatively few in our industry.

This book is a humble attempt to make these concepts more accessible to SQL developers. We consider this book a first version of the ongoing research in this area. Of the hundreds of wait types, this book covers the most visible ones. This initial volume doesn?t cover the wait statistics with less significance or ones seldom seen. Again, every wait type potentially has multiple solutions and we have attempted to cover the common solutions. While you read and implement suggestions, we highly recommend that you attempt them first on your development server before implementing them on your production server.

Please send us feedback as you try out various solutions based on the wait types. We will incorporate your experience in a future version of the book, which will include an expanded write up with more real world scenarios and many more wait types.

About the Author
Pinal works as a Technology Evangelist with Microsoft India. He has been a part of the IT industry for more than seven years. During his career he has worked both in India and the US, primarily with SQL Server Technology - right from version 6.5 to its latest form. Pinal has worked on many performance tuning and optimization projects for high transactional systems. He received his Master of Science from the University of Southern California and a Bachelors of Engineering from Gujarat University.

Additionally, he holds many Microsoft certificates. He has been a regular speaker at many international events like TechEd, SQL PASS, MSDN, TechNet, and countless user groups.

Pinal writes frequently on his blog http://blog.SQLAuthority.com on various subjects concerning SQL Server technology and Business Intelligence. His passion for the community drives him to share his training and knowledge. Before joining Microsoft, he was awarded the Microsoft Most Valuable Professional (MVP) in SQL Server Technology for three continuous years for his outstanding community service. He was also awarded the Community Impact Award ? Individual Contributor for Y2010. When he is not in front of a computer, he is usually travelling to explore hidden treasures in nature with his toddler daughter, Shaivi, and very supportive wife, Nupur.

In 1994 you could find Rick Morelan braving the frigid waters of the Bering Sea as an Alaska commercial fisherman. His computer skills were non-existent at the time, so you might not imagine such beginnings would lead him to SQL Server expertise at Microsoft. However, every computer expert in the world today woke up at some point in his or her life knowing nothing about computers. They say luck is what happens when preparation meets opportunity. In the case of Rick Morelan, people were a big part of his good luck.

Making the change from the fishing industry seemed scary and took daily schooling at Catapult Software Training Institute. Rick got his lucky break in August 1995, working his first database job at Microsoft. Since that time, Rick has worked more than 10 years at Microsoft and has attained over 30 Microsoft technical certifications in applications, networking, databases, and .NET Development.

Great book, highly recommended

This book could be called 101 Best Wait Stats Solutions, and the title would probably only be inaccurate because there are more than 101 solutions in this book. There are almost 500 different wait types in SQL Server 2008, and that number is only going to increase over the next versions, so learning how to deal with wait stats now is very important. I think the best part about this book is that the author uses real world examples from his own experience in dealing with SQL Server, and also encourages feedback from his readers about what to add and improve. It’s almost like taking a SQL Server wait stats course, but you just have to pay for the book. There are ten chapters in this book, and they are laid out from simple ideas (“Introduction to wait stats”) through more complex. This makes the book a good reference for beginners and professionals. I would highly recommend SQL Wait Stats!

Practical Book on Wait Stats

In a recent customer performance trouble shooting exercise they were getting into some sort of slowness in their application. Running couple of queries found some interesting insights into Wait Stats which was nicely explained in a whole chapter for CXPACKET.

More than just a reference this is a practical book on some of the major WAIT STATS which even a novice DBA can also easily understand.

A must buy for any DBA monitoring critical production environments and for those who are into advanced performance tuning.
