Oracle Performance Tuning For 10gR2 by Gavin Powell ebook DJV, FB2, PDF
9781555583453 English 1555583458 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. *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 *Fully updated for Oracle Database R2, Tuning of SQL code is generally cheaper than changing the data model.

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, Tuning of SQL code is generally cheaper than changing the data model. This work includes the 3 aspects of Oracle database tuning: data model tuning, SQL & PL/SQL code tuning, and physical plus configuration tuning. It also offers guidance and examples using large datasets and emphasizes development as opposed to operating system perspective.
