Oracle Performance Tuning for 10gR2by Gavin JT Powell
Tuning of SQL code is generally cheaper than changing the data model. Physical and configuration tuning involves a search for bottlenecks that often points to SQL code or data model issues. Building an appropriate data model and writing properly performing SQL code can give 100%+ performance improvement. Physical and configuration tuning often gives at most a 25%
Tuning of SQL code is generally cheaper than changing the data model. Physical and configuration tuning involves a search for bottlenecks that often points to SQL code or data model issues. Building an appropriate data model and writing properly performing SQL code can give 100%+ performance improvement. Physical and configuration tuning often gives at most a 25% performance increase.
Gavin Powell shows that the central theme of Oracle10gR2 Performance Tuning is four-fold: denormalize data models to fit applications; tune SQL code according to both the data model and the application in relation to scalability; create a well-proportioned physical architecture at the time of initial Oracle installation; and most important, mix skill sets to obtain the best results.
• Fully updated for version 10gR2 and provides all necessary transition material from version 9i
• Includes all three aspects of Oracle database tuning: data model tuning, SQL & PL/SQL code tuning, physical plus configuration tuning
• Contains experienced guidance and real-world examples using large datasets Emphasizes development as opposed to operating system perspective

This is the first book I have read from Gavin Powell and Digital Press. The book is excellent. Gavin's approach to helping you understand the concepts are displayed well with code examples. You will read a passage and then see an example to really enforce the principle. The examples support the concepts and using both together helped me out a great deal. The chapters on Tcp/ip and DSM SUBSYSTEM I found to be really helpful. This architecure chapter goes in much needed detail as so many books just glance over the different Oracle tuning. What the processes are used for and how they can be tuned is well documented. The ODBC chapter helped me understand how to configure and best to take its advantage its fullest level for a given situation. At the end of the sql/mx chapter Gavin has a section on specific tuning and this section should be required reading for all DBAs and developers. Something else I got from the book are methods for writing SQL and tuning it. The SQL that the author puts together looks so easy and natural for him to write. He is a master of SQL*Plus and that is a side benefit to reading the book. The techniques I picked up from reading Gavin's examples will help me just as much or more so than content of the book. This book is an excellent addition to my Oracle collection of books and I highly recommend reading it.
