Query: Rare O-Reilly dissapointment

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.
