A completely revised version containing updates through to Oracle10gR2. Still includes from 9i to 10gR2. Oracle Performance Tuning for 10gR2, Second Edition Gavin JT Powell Independent Consultant and Oracle Certified Professional, U.S.A. KEY FEATURES: *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 DESCRIPTION: Because Oracle has cooperated in giving the author access to its beta program, this will be the first to market among 10gR2 tuning books. Powell shows that the central theme of Oracle9i-10gR2 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. Tuning of SQL code is generally cheaper than changing the data model.

Physical and configuration tuning involves a search for bottlenecks which will often point to SQL code or data model issues anyway. Building an appropriate data model and writing properly performing SQL code can give 100%+ performance improvement. Physical and configuration tuning often only gives at most a 25% performance increase.
