We have used Built-in Functions since the beginning of DB2, however nowadays when DB2 releases come out some of our old friends do not quite work the way they used to. This presentation will explain :
- What a BiF is
- How you can find out details
- Show real customer results from a BiF hunt
“But that’s the way we’ve always done SQL Tuning” – sound familiar?
The definition of madness is to keep doing the same thing and expecting a different outcome.
Find out how to stop the madness.
“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.
1 – Tuning SQL – how we always done it
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
