Workspace Db2 AI for z/OS
Created by Guest
Created on Jul 24, 2025

Improve visibility of choosen access path after rebind

We are using Db2 AI for z/OS with and without validation of the provided optimizations in SQL Optimization.
For the option "with validation" you can see in the details table from the improvement which access path would be choosen after the rebind.
If you use "without optimization" there is no information about what will be used after the rebind. From our information in a recent case we now know that it is always the ML optimization model instead of the basic optimization model.

We think it would be a good enhancement if Db2ZAI could highlight the model which will be choosen after the rebind for all situations (with and without validation). So you can see much faster and clearer what will change after the rebind. This is especially important for packages which are used very often.
