A very simple but very useful method of SQL tuning is described
Analysis of bottlenecks
Numerous examples facilitate to get into the subject
Enables SQL tuning by removal of brakes in the execution plans
Leonid Nossov was born in Yakutsk, studied mathematics in USSR and has worked in Germany as an Oracle spezialist for several software companies. In the last few years he has been in Advanced Customer Support at Oracle Germany. His work mainly involves performance tuning and troubleshooting.
Hanno Ernst comes from Zschopau in the Erz Mountains. Since qualifying as an electronics technician in communications technology at German Telecom he has been in Bamberg at the German Telecom subsidiary T-Systems. His main task is database administration and he is particularly interested in error and performance analysis.
Victor Chupis was born in Odessa, USSR. He studied electronics and information technology in Moscow. Since 2001 he has been working for Vodafone Germany. His special fields are database design, operations and performance tuning.
The target of SQL tuning is the improvement of the existing execution plan. The authors discuss the removal of brakes in the execution plan. Such "brakes" or bottlenecks can be recognized by a formal analysis of the execution plan. For this purpose no data model knowledge is needed. This is especially beneficial for database administrators because they are usually not or insufficiently familiar with the data model. The book presents numerous practical examples with this method.
Prefaces.- Introduction.- Some thoughts concerning the term "SQL Tuning".- Minimum minimorum to the subject "Execution Plan".- Approaches to formal SQL Tuning.- Bottlenecks in Execution Plans.- Procedure for formal SQL Tuning.- Practical experiences with formal SQL Tuning.- Appendix.- Application of the formal method for analysis of performance issues following Oracle migration.
