Session title: Let Me Make This Clear (Vol. 4): Explaining Often-Misunderstood Db2 for z/OS Concepts and Facilities


Speaker: Robert Catterall, IBM


Session abstract:

Some aspects of Db2 for z/OS technology are plain as day; others, less so. Questions I get from Db2 users worldwide have highlighted for me things that a lot of folks – even experienced Db2 people – tend to misunderstand. From AI in Db2 to dealing with old Db2 client code, from data set encryption to temporary tables, in this fourth iteration of my "Let me make this clear" presentation I'll try to take folks from "Uh" to "Oh!".
