25 Years of Missed Opportunities? SQL Tuning Revisited

Nothing is more expensive than a missed opportunity” (H. Jackson Brown, Jr).

This is especially true when it comes to SQL Tuning!

There are many low-hanging fruits within easy grasp of anyone tasked with tuning their systems. But how do you know what is dangling within reach if you can’t see it?

Find out how a modern DB2 z/OS SQL warehouse can collect and store all executed static and dynamic SQL (plex-wide) with basically no overhead.

By comparing SQL statements side-by-side, the “easy pickings” will immediately become apparent. But why stop there? Experts can effortlessly dig deeper and find the totally hidden gems: Disc Problem Detection, Delay Detection, Never executed SQL, SQL Timeline. Precisely pinpoint specific areas to target and get the most out of your DB2 system – while reducing costs.

 

Outlines

2 – Single SQL, package, application

3 – Tuning SQL – year 2004 – ACCESS PATH comparison and simulation

4 – Tuning SQL Revisited – A new methodology

5 – Harvesting the low hanging fruit
