Query: Where are the details?

The utilities explained in this book lack details. Which is a critical flaw for a book professesing to explain utilities. Virtually every utility explained in this book had to be researched further by me in the internet to gain a better understanding of when and how to use it, which, of course, defeated the purpose of me paying good money for this book.One exception, TKPROF is explained beautifully and in detail. Otherwise, the real value of this book is the author's list of Oracle's most useful utilities.
