SQL Optimizer for DB2 ZOS 5.5.1 - Installation Guide

Automatically Optimize SQL Statements

Use the Auto Optimize function to perform the optimization and testing processes simultaneously. The function optimizes your original SQL statement by generating alternatives and starts testing once SQL Optimizer generates the first alternative. The Auto Optimize function reduces the time required to find the best alternative by not waiting until SQL Optimizer generates all alternatives before starting the testing process. You can stop the Auto Optimize function once you find a satisfactory SQL statement alternative.
