This book is an oldie, but a goodie, and I finally managed to get through all the pages. I hate my self for not having done that for many years ago.
This book is a technical book, and it covers a lot of serious aspects related to troubleshooting; from DBCC to Memory preassure; from IO problems to CPU problems.
The best thing is that it mentions a lot of Dynamic management views that are still very relevant.
So. If you a skilled SQL person, and you want to learn more about Troubleshooting, then this is a must have book.
