Expert Oracle: Signature Edition (Expert One-On-One) ReviewThis book belongs on every developer, team leader, or DBAs desk that works with Oracle. Kyte has written a masterpiece in advanced Oracle knowledge. He does three things very well in this book: tells you what is important in Oracle, why it is important, and what happens if you do things the wrong way.
Kyte starts out giving the foundations for Oracle databases, the architecture, locking schemes, and table and index considerations. He gives a good treatment of the types of tables and indexes that Oracle offers including the appropriate times to use them and the trade-offs to weigh.
Another key topic that he covers is redo and rollback. These features are handled in a unique way in Oracle, and a lack of understanding can lead to inefficient and incorrect databases and applications.
Armed with the foundations, Kyte then takes the reader through performance tuning and optimizing databases. The best advice in this section is that performance cannot be thrown in at the end. The design decisions for a database will determine how it performs and scales. As he says, "There is no fast=true setting in the init parameters."
Then the book tackles some more advanced features, such as autonomous transactions, dynamic sql, and C and Java extensions for stored procedures. Kyte again gives good advice for when these are appropriate over standard PL/SQL stored procedures.
The size of the book can be intimidating at first glance, but it is pleasant to read. Kyte uses a conversational style rather than a lecturing delivery. This book has a lot to offer, and you won't find yourself tired after reading it.Expert Oracle: Signature Edition (Expert One-On-One) Overview

Oracle 11g Streams Implementer's Guide ReviewI went through the sample chapter of this book at the Packt Publishing site, "N-Way replication" and found it with good technical deepness and detail, so I decided to go for the whole book after wards. I'm greatly surprised because got practically 2 books for one, let me explain: the first 3 chapters provide a foundation on Replication and Oracle Streams, but the Replication part is really good for anyone getting serious about replication, with detailed explanation, proper terminology, a very good implementation methodology proposal, and so on. I've worked with replication for 5 years now on SQL Server, MySQL and Oracle and for instance chapter 2 provided me a complete new framework and refreshed my own method. Chapters 4 and 5 provide a very detailed implementation, a commented walk through on the newest Enterprise Manager windows specific to "Information Movement" that allow you to grasp the basics in one hour if you're in a hurry... however, my suggestion is don't get in that position and buy this book right away and read it cover-to-cover, at the end you'll be at strong-intermediate level, with knowledge to cover all bases, and hungry for getting more advanced on Oracle Streams and replication.Oracle 11g Streams Implementer's Guide Overview

Oracle E-Business Suite Development & Extensibility Handbook (Osborne ORACLE Press Series) ReviewI've been an Oracle Applications technical consultant for over 10 years and during that time I often used Anil's web site [...] as a resource when I ran into new issues. Now with this book, I have a well-organized volume with all that info and more. In every section, I find new nuggets of information and new techniques that I haven't run across before, each with examples so I can readily make use of them in my work.
There are a lot of OA extension and customization requirements that just don't come up often enough to stick in your memory. If you're like me you remember that you did something like that before and you think it was for this client or that, but you certainly don't remember the name of your program and finding it can be a chore. Chances are good that whatever that technique is, it is either in this book or something here will be close enough to trigger the memory banks to bring it to the surface.
Because everything is explained with examples, this is a great book for someone starting out as a Oracle EBS techie also. I would strongly recommend that anyone doing customizations and extensions, or forms, reports and interface development buy this book. You won't be sorry.Oracle E-Business Suite Development & Extensibility Handbook (Osborne ORACLE Press Series) Overview

Oracle Performance Survival Guide: A Systematic Approach to Database Optimization ReviewMr. Harrison has been a respected author in this field for more than a decade. His writing back in the days of version 8 first opened my eyes to the world of Oracle performance tuning. When I learned that he published this new book, updated and greatly expanded in scope, I just had to read and devour it.
This book is an encyclopedic overview of all aspects of Oracle performance. Mr. Harrison takes a layered approach, starting at the top with application and data model design where the focus is minimizing the demand for database resources. He then moves down into database code internals, where the focus is maximizing concurrency through reduction of lock, latch, and mutex contention. The next step is to optimize memory usage to minimize the need for physical IO. Finally, he moves to the bottom layer, where the focus is on optimizing physical IO at the disk layer.
Each of these layers is worthy of its own book, so to combine all these topics in a single book is an ambitious goal. Indeed, experienced readers will often want a bit more detail, or wonder why their favorite optimization was not mentioned. However, Mr. Harrison strikes a very good balance between depth and coverage. He also provides a very useful bibliography, including the Oracle documentation, books, and Internet sites and blogs.
For each chapter, Mr. Harrison provides extraordinarily clear, concise, and helpful introductions and summaries. He also uses boxed borders to highlights particularly important points within the text. One can learn a great deal by simply reading these summaries and boxed items, and these can also be used to help the reader find relevant sections, which is especially valuable in a book of this length.
This book is not the last word on SQL tuning, optimizer internals, Oracle troubleshooting, the SGA, nor latch contention. However, its coherent approach, useful summaries and highlights, and efficient organization, make it a valuable and essential guide to anyone wishing to expand their Oracle performance skill set.
The target audience includes both application developers and DBAs. It covers 10g, 11g, 11gR2, with context from 8i and 9i.
