SQL Optimizer for DB2 ZOS 5.6.1 - Installation Guide

About Optimizing SQL

The Optimize SQL function analyzes the input SQL statement and uses an Artificial Intelligence Engine to produce a group of semantically equivalent versions of the statement, known as SQL alternatives. You can then test run these alternatives in the SQL Optimizer window to determine the best-performing version of the SQL.

Note: The Intelligence Level setting you select affects the duration of the optimization process and the number of alternatives SQL Optimizer generates.
