Summary: Rehash of information already in Parallel Server Documentati
Review: I found that this book contain lots of info that is already present in the Oracle Documentation. Actually some of the SQL queries (even with mistakes) are directly copied from the Oracle Parallel Server Doc (7.3+). I don't see any additional information added that is new in this book. Not sure if the authors have seen any large production Parallel Server systems, but there is no usefull real life information in this book. For example how to tune large Oracle Parallel Server Systems. If you want a summary of the oracle doc, then you should buy this.

Summary: An Excellent Book of O'reilly
Review: I refer this book as a Parallel Processing and Parallel Server MADE EASY. If you are a serious Oracle DBA then this book is for you. This book is the single point of Source for many of PARALLEL Processing/Server related questions. Use this book to boost your system performance. This is the only book all database professionals need to start working with Parallel Processing and Parallel Server. Every Oracle DBA should read and use this book. I strongly recommend this EXCELLENT book.

It completely touched all about Parallel Processing Architecture, Concepts, Tuning with numerous examples. It covers OPS architecture, Administration, Concepts, Storage, Tuning, Partitioning, Failover in depth in simple words. For me this is RIGHT BOOK AT RIGHT TIME.

Summary: Good For Novice DBA
Review: Some of the content in the book is an hardcopy of the Oracle Documentation. I expected more real time scenario's. This book is good for beginner in OPS Environment. Overall Content Presentation is good.But not upto Standards Middle level DBA or Senior DBA level.

Summary: Nice rocking chair reading
Review: The book describes the Oracle parallel concept and features in an easy understandable way by words, repeating the same information several times on different pages. But even basic admin knowhow (e.g. how to access a parallel server db by Net8), useful SQL-code examples (forget about the bunch of selects shown how to query a V$-view) and clear detailed strategies how to do (e.g. what is a good estimation for the value of the DEGREE parameter) are missing. I easily got through that book in one evening sitting in my rocking chair. And I did not miss my computer with Oracle on it. Make the philosophical text half as long by cutting away what is said twice, and use the pages for the "real stuff", then you will have a usefull book. The 3 stars rating basically reflects its repertoire value.

Summary: Well Done!
Review: There are not many books available, except for Oracle Documentation, on the topic of Oracle Parallel Processing and Parallel Server. Trying to learn the parallel processing concepts from documentation is not that easy. This book offers an excellent introduction to the world of Oracle Paralell Processing. Some parts may be rehash of Oracle documentation but then Oracle Parallel Server and Parallel Processing concepts are quite complex and the authors have done a great job in presenting the information in clear and concise manner. I agree that this book may not add value to people who are very well experienced in large (terabyte) parallel databases, but new comers to Oracle Paralell Processing will definitely benefit from this book.

Rating:
Summary: Well done . . .
Review: This is a excellent book that goes over what you need to know about Oracle Parallel Processing. The documentation is clear and concise. If additional information is need, references to Oracle Documentation are noted throughout the book. Picking this book up just for the Parallel Execution chapters (Ch 3 - Ch 5) is worth it even if you are not using Oracle Parallel Server.

Summary: Rare O-Reilly dissapointment
Review: Unfortunately, I usually trust that I can pick up an O'Reilly technical book and be confident that it is one of the finest works both for accuracy and completeness of content -- this title is the rare exception.

I have been developing for and managing terabyte plus Oracle databases for a number of years -- this title lacks the practical gotchas and information needed to effectivly manage and develop parallel systems with any degree of complexity.

If you have a large database and need to break simple jobs up then you may find the title has adequate coverage; however, if you are dealing with complex data models, with situations where you have a great deal of object colision (and hence waits and latch contention), then this title will not meet your needs.
