Screencast 12 - Get WLM Set Up Right For DB2

In it I talk about the important topic of ensuring DB2 is protected against shortages of CPU (and zIIP). There are a couple of quite nice examples to illustrate the point.
I should note that I don’t see instrumentation that explicitly shows what happens when IRLM gets heavy competition for CPU. I’m more concerned to show - as one of the examples does - that DBM1 can be significant so it’s worth keeping below IRLM.
This was the first time using Camtasia where I pruned out silence at the final - audio and video recombined - stage. I think I’m finally getting the hang of the tool and there’s a certain amount of muscle memory developed now.
Also, and I hope it doesn’t show too much, my editing of the audio (with Audacity) involved getting rid of a lot of huffing and puffing. I’d like to believe I wasn’t getting (too) old (to record) and that this was just a cold. It seemed to me the more excited I got the less the huffing and puffing. I’m not sure if there’s a life lesson there or not.
