Oracle Core: Essential Internals for DBAs and Developers by Jonathan Lewis provides just the essential information about Oracle Database internals that every database administrator needs for troubleshooting―no more, no less.
Oracle Database seems complex on the surface. However, its extensive feature set is really built upon upon a core infrastructure resulting from sound architectural decisions made very early on that have stood the test of time. This core infrastructure manages transactions and the ability to commit and roll back changes, protects the integrity of the database, enables backup and recovery, and allows for scalability to thousands of users all accessing the same data.
Most performance, backup, and recovery problems that database administrators face on a daily basis can easily be identified through understanding the essential core of Oracle Database architecture that Lewis describes in this book.

SHOCKING, ABSOLUTELY SHOCKING!
By Bassocantor
Yes, I was shocked by this book. Had absolutely no idea it would be as comprehensive as it is. Where does this guy get the time to do all this research? I agree with other reviewers who suggest this book sets the standard for Oracle internals. This book is definitely one of a kind.
The greatest value for me was Chapter 3, "TRANSACTIONS AND CONSISTENCY." I was investigating performance issues with a flashback query, and this chapter had the answer. It was due to the "Transaction Table" rollback. I have not found this valuable information anywhere else. There was not one DBA amongst the 24 I work with who knew this information (I admit I certainly did not.) The author gave me several good tips on how to identify when your database is performing lots of transactions table rollbacks. This was all excellent and very practical.
The main suggestion I have is on the writing style. The effort required to read this book is formidable. That is what kept me from giving the book six stars, instead of just five. Here's the point--we techies have difficulty presenting complex subjects in an understandable fashion--we just want to get into the details, and not waste time on preliminaries. That's why presentations by techies at conferences are often terrible and unreadable. (To clarify, I've attended talks by the author, and he does NOT make that mistake at conferences.)
When discussing a complex topic, the text sometimes goes quickly into very detailed specifics, with just a sketchy overview beforehand. The author is so anxious to get into the nitty gritty data, he doesn't give us a chance to catch up with him. This makes it tougher for mere mortals to follow Mr Lewis. I think far more people would benefit if there were more pages with overviews of a topic first, before showing hex dumps and details of x$ tables.
The point is, being technically correct is not good enough. When trying to explain complex subjects, presentation is not just an option--it is critical. For example, on page 27, discussing transaction tables and undo, there is a small visual at the top of the page, with scant discussion--then, a few lines later, the author immediately dives into hex dumps. The point is, most readers need to understand overall concepts first. The hex dumps can be supporting data--but not the primary focus of the discussion. So, in this section, without this preliminary, it took me some time to get the gist of what the author was saying. All the data got in the way. I wanted to know how something worked, not what the column "wrap#" means. Maybe afterwards I'll look over the raw data--but that should be secondary, not primary.
The smallish text didn't bother me too much. I guess my reading glasses were powerful enough.
I agree with the reviewer who questioned the "Beginning to Intermediate" note on the rear cover. I seriously doubt that any beginner DBAs are ready for this book (and probably no Intermediate either.) Also, I wonder if the book is really suitable for "DBAs and Developers," as stated on the back cover. I know of zero developers who would be able to follow the discussion on read consistency. Of course, I must admit that the developers who work with the author may be far more proficient than the ones I know.
Despite the above criticism, this is really a great book. The investigations and tests that the author present are really stellar, and I think the Oracle community really owes a debt to Jonathan Lewis. I'm pretty sure that much of this information is not easily available anywhere else (maybe nowhere else?)
This book sits on my desk with several "sticky notes" stuck in it. Still trying to figure out that hex dump on page 27 ...

very readable and helpful
By daniel zika
The book is extremely readable and understandable even for non-native engl. speakers. It gives a lot of insights and facts of how things work in a perfect way, as author says "in circles".
It doesn't make one better programmer, but helps one to understand what his/her code does ( or might do ) and why ( or why it can't ). I like are the summaries at the of each chapter, refreshers before next topic.
From my developer's point of view I can recommend the book to all who want not just to write a pl/sql code, but want to understand why Oracle is behaving the way it does.

By Martin Silveira
This book is great for Oracle freshers and for those who has some intermediate knowledge of the DBMS. It contains almost everything you need to know for regular troubleshooting, very good scripts for performance issues, storage, etc.
