Every Oracle professional should feel the exhilaration of adding a single function-based index and seeing the execution speed cut-in-half for 500 SQL statements. It`s these silver bullets that can make you a hero in your shop and amaze your friends and associates.
All Oracle tuning professionals know that they must start by optimizing the database as-a-whole before tuning individual SQL statements. Only after you have tuned the external hardware (disk RAID, network, OS kernel parms) and the instance (indexes, CBO statistics, optimal parameter settings), is it appropriate to tune individual SQL statements and application code.
A single change to the optimizer can improve the behavior of hundreds of SQL statements, and database-wide tuning approaches such as adding a missing index, creating a materialized view or adjusting CBO statistics must be done before detailed SQL tuning can happen.
These silver-bullet recommendations have been codified inside the Oracle 10g Automatic Database Diagnostic Monitor (ADDM), and every Oracle professional must recognize the benefits of these important tuning techniques.
Oracle consultant Don Burleson shares his in-the trenches Oracle tuning secrets in this concise and practical book. Packed with actual techniques and tips, Burleson shows you how to perform system-level tuning on all Oracle databases, from small OLTP systems to giant data warehouses.
This is the definitive collection of professional system-level tuning secrets for every Oracle professional DBA.
