Oracle Database 11g Release 2 Performance Tuning Tips & Techniques (Oracle Press)

A must have. Read it all - bypassed admin stuff as im more interested in developing and this book really opens up all oracle internals and how higher level stuff gets implemented ..learn that those v$ views really are implemented via x$ that read oracle internal ram data structure - not that we will use x$ but was great to understand from ground up what an oracle instance does when loading up, lots of knowledge being shared about all things oracle uses to support its run time lovely book a must.. i would say 50% about oracle architecture insights and remaing 40% usefull developer lots of hints and usefull sql.. with 10% +/- just lots of reference tables in the end of book. Book also does good job explaining how to monitor via both admin console as well the sql that web admin tools use themselfs ..at least a more then good sql ..one will collect and learn a lot about common oracle views that help with lots of scenarios questions.. indexes also explained very well with all type of indexes, best use of each type.. concepts like index fragmentation etc lovely book and a must have.

I'll start with the good: The book is very comprehensive, and it's evident that the author put a great deal of effort into writing it. A few of the chapters, individually, are worth the price of the book.Unfortunately, the book is also filled with outdated advice, and statements I had considered flat-out wrong or at the very least ostensible. I actually kept track of these statements but eventually gave up because the list was growing too long; I bought the book to learn more about Oracle performance tuning, not to be a technical editor for it.In the end, I would recommend this book be used to strengthen your performance tuning knowledge. Use it to supplement the excellent documentation that Oracle makes available free of charge (including the Performance Tuning Guide).

I found this book very useful as it is direct, and points many ways of doing a tuning in a query, server, database or application code, even when it is a third party app for example. Rich Niemiec knows a way to teach that you learn easily and fast, and in a very productive manner. He gives real life examples and shows you the code for eeverything. It really is a must have DBA book, if you take Oracle for serious and want to take the most of your database.

This is really good book,pros - relates one thing to another like a real world examplecons- Dev, DBA related things are mixed and sometimes confuses if you skip chapters

i did not have time enough to go thru all of its content, but seems to be a good guide

Great book for DBA and developers as performance tuning reference. I can say it is fundamental on every topic but it is great in wide view on many topics associated with the performance tuning.

Se toma todo lo necesario para optimizar pero falta más profundidad en temas de racismo. . . . . .

The Oracle database versions have changed as much that you need a concise reference for the exact use to to put the database too. Getting more from your software and hardware you need tune the two elements to cooperate and help you make the most of your investment. This book does precisely that and helps you not fall into old habits from previous versions of the software.

Muy buen libro, vienen muchos tips que en lo personal ni tenia idea de las cosas que puede hacer Oracle con muchos ejemplos.

It's good

Atendeu totalmente minhas expectativas.Livro com bastantes aspectos tecnicos relevantes, em especial para o tipo de trabalho que preciso realizar.Att.

no llega en fecha estipulada, no existe claridad si llegara o no o si existe algun problema en la entrega final

Perche', esasperato dall'impossibilita' di leggerlo sul mio adorato Kindle, ne ho acquistato una copia cartacea: (fra tutto ho speso piu' di 60 euro!!)(siamo tornati all'epoca di Guttenberg). letta e riletta, la copia cartacea, mi sento di dire che e' una grande opera scritta, forse con troppa enfasi, da un grande tecnico:. Un po' troppo mistico ma grande tecnico!!Mi e' piaciuta l'esposizione lineare degli argomenti, Gli approfondimenti, e gli esempi.Non mi e' piaciuto come vengono presentate le parti che, pur essendo testo, sono circoscritte in box grafici che kindle non sa interpretare. Questa e' la ragione per cui, dopo aver chiesto support a Amazon che non ha trovato soluzioni, ho dismesso il libro in format Kindle e ho acquistato il libro cartaceo.Chi e' interessato ad Oracle in modo professionale (non hobbistico ohibo'!!) trae enorme vantaggio da questo volume di 1140 pagine.Un consiglio: Non perdetevi negli sperticati elogi che l'autore fa a tutto, anche al cane dell'editore: se si potessero eliminare queste stupide ridondanze, il libro sarebbe di meno di 500 pagine e sarebbe molto piu' leggibile.Torno a dire che lo consiglio a chi, come me, svolge giornalmente una professione di Consulenza sull'internal di Oracle.Oracle non e' un paese per vecchi!!
