Advance Query Tuning with IBM Data Studio
Tony Andrews, Themis
In my opinion, one of the best query tuning tools on the market. And if I’m running a project, every developer should have this tool on their desktop. If you are often curious ‘why’ the optimizer chooses a certain index, join order or access path then this tool will get you those answers. And by doing so helps to get the right solution for query improvement. This presentation is designed for the Db2 professional who desires to understand the fundamental issues with performance for Db2 applications. Emphasis is placed on understanding optimization, many access paths chosen by the optimizer, filter factors, along with how to read and understand visual explain access paths. Performance related issues in the areas of database design, indexing, application SQL coding, and data statistics will be addressed. Presentation has examples in both Db2 z/OS and LUW.
