5.0 étoiles sur 5 Does Richard Niemiec need any comments 18 décembre 2012
Format:Format Kindle|Achat vérifié
As a DBA, I need from time to time some very precise input and Richard is very good at that.
He has understood what we need on the job and put it in a way it's a valuable repository of excellent receipts.
Thanks so much for that.

4.0 étoiles sur 5 Good but not perfect 13 mai 2012
Par John Watson - Publié sur Amazon.com
Format:Broché
The book is aimed at "helping beginner and intermediate Oracle professionals" (page 2). Presumably that means knowledge equivalent to OCA or OCP qualifications. For the intended market it should be excellent, if (like me) you are OCM, you will learn not that much. But there are some issues.
The good stuff first: chapters 2 (indexes), 6 (explain plan), 7 (hints), 8 (query tuning), 9 (joins), 10 (pl/sql), 11 (parallelism only - ignore the stuff about Exa% and RAC, they can't be covered in just a few pages), 12 (v$ views) and 13 (x$ tables) are excellent and make the book worth the price. They get it the 4 star rating.
Some other chapters (and the 3 appendices) may be interesting, but they aren't essential reading: chapters 1 (new features), 5 (Enterprise Manager), 15 (a system review method), and 16 (some Unix commands).
Three remaining chapters are good, but have problems. Chapter 3 on discs and ASM does go on about placing files on different discs to eliminate contention. This is dreadfully old fashioned, and I assume has been copied from previous versions of the book. I hope everyone knows that best practice is to stripe all your file systems across all your discs. Chapter 4 (initialization parameters) is also out of date: it goes on about tuning with hit ratios, which is very 20th century. Chapter 14 (AWR and Statspack reports) is good as far as it goes, but it misses a critical topic: there is no mention of DB Time and v$sys_time_model, even though this is the first part of a report that many DBAs will go to.
Now the bad stuff. First, the technical editing is poor. All authors make mistakes (I certainly do) and the tech editors are meant to catch them. Just a few incontrovertible examples:
Page 4, the description of Exadata storage indexes is wrong, "...which cells need to be accessed..." should read "...which blocks need to be accessed..." Pages 21,22 include an example of code to set up a flashback data archive, which ends with a query that can't work because it projects a column that isn't in the table. On page 334, the first example can't work because the hint is missing the table name. There are many more like this, I'll send all the ones I spotted to McGraw-Hill for inclusion in the errata sheet. Things like this are not trivial, they can be confusing or misleading. Be sure to download the errata.
Second, the bad one: the author is wrong on how redo is generated. Page 147 gives a description of redo which suggests that only committed changes and changes to undo segments generate redo, but that uncommitted changes do not. Page 782 compounds the error by suggesting that redo is no longer written to disc in near-as-damnit real time (and of course it is real time on commit), and page 866 makes it even worse by saying that whole blocks (not change vectors) go to the log buffer (as in release 5, perhaps?). Related to this is the wrong description of the log_buffer parameter (page 204, repeated on 1004) which states that the log buffer is used for "uncommitted transactions in memory". It also says incorrectly that you cannot set the parameter in an spfile. Understanding redo is critical, and is why I chopped a point off the score.
So overall, the book is good, but read it with your eyes open.

5.0 étoiles sur 5 Comprehensive Guide for Developers and DBAs 4 mars 2012
Par Robert Stackowiak - Publié sur Amazon.com
Format:Broché
You'll find plenty of examples of techniques to use when tuning for Oracle Database 11g Release 2 performance, especially at the command line level. However, the book also does a credible job of providing examples of tuning using Enterprise Manager. It clearly lays out which chapters that will be especially relevant for DBAs, developers, or both, and at what level of expertise (from beginner to advanced). Exadata users will find a chapter devoted to this topic including the unique features available on that platform. This is a must have book for DBAs that want a single resource to go to when faced with a performance issue.

5.0 étoiles sur 5 Essential Tools for any Oracle Professional 6 mars 2012
Par Ken N - Publié sur Amazon.com
Format:Broché
This book is an essential tool that should be in every Oracle Professional's bookcase. It has value as a reference to fix performance issues that are currently present or as a study guide to take a beginner/intermediate DBA and/or Developer to an expert. Rich Niemiec brings performance tuning down from a mystical art down to a science with each topic covered concisely and thoroughly with clear instructions on how to implement them. Readers of previous versions of this book have a section that documents how each chapter has been updated. My favorite chapter is the one on Exadata as it really brought it home for me. It is a great tuning reference for developers, also it is one very few books cover the rare V$ views, X$ tables including how to query them.

I highly recommend this book especially for everyone looking to get the most out of their hardware. Why pay for new hardware when you can dramatically improve the performance of your current one using the information contained in this book?

5.0 étoiles sur 5 Packed full of practical advice 12 mars 2012
Par Chip Dawes - Publié sur Amazon.com
Format:Broché
There are several books that I proudly keep on my bookshelf and reference frequently (in addition to my own PL/SQL pocket reference and my OCP study guides). Tom Kyte's Database Architecture, Craig Shallahamar's Forecasting Performance, Steven Feuerstein's Programming PL/SQL and Rich Niemiec's Tips and Techniques. There is so much good stuff in these books and from these smart guys. Whenever I'm asked "how do you know so much?" I explain... On Mondays I read a man page (from Linux, Solaris, AIX or HPUX), Tuesdays I read AskTom, Wednesdays is the PL/SQL challenge, Thursdays is a deep dive into a Shallahamer topic and on Fridays I read a Rich Niemiec tip or technique. Each day of the week brings a review and insight into the how-to and best practices that experienced engineers need to know.
In this book, Rich has shared a vast knowledgebase of information on what actually works in managing Oracle databases. The information in this book comes from real life experiences. Rich's tips and techniques are firmly rooted in practical experience. There are lots of experts but they mostly reference the really smart guys - Tom, Rich, Steven, Craig. Learn the best from the smartest - get this book and every week, discover something insightful.

5.0 étoiles sur 5 A Cookbook For Success 13 mars 2012
Par Michael Anthony - Publié sur Amazon.com
Format:Broché
This book is a must for every Oracle professional. It is full of information from the Intro which gives us a nice history of Oracle and the future ahead of us to the plethora of technical tips and techniques.

Richard Niemiec has always been a fantastic author and teacher; and continues to be with this book. It has over 1100 pages of useful tuning tips and techniques. Rich takes the time to provide real life examples and illustrations to guide us through solving the performance problem du jour.

In today's times with budgets being cut and time being so precious we may not be able to spend 3 - 5 days or several thousand dollars on a training class. If that's the case this book is well worth the price. And if you can afford the time and money to take a tuning class this book is a great tool to augment what you learn.

My recommendation is to use this book like a cookbook. Read the intro to get a sense where the author is coming from and then the first couple of chapters to get a feel for the book. Then every day or so read a different chapter; by the time you are done you will know what to do when a problem arises and more importantly what to do to prevent the problem in the first place. Like any good cookbook full of fantastic recipes that we all can follow this book will soon be dog eared, have notes in it and spills on it.

Another superb job by Richard Niemiec.
