Techdocs : Flashcopy & PPRC
It's been a while since I mentioned any interesting reading material from Techdocs. But now there's some nice presentations on Flashcopy and PPRC. The first one is "Flashcopy in a zSeries environment" describing how FlashCopy works, its different functions, and how to invoke those functions using DFSMSdss, TSO, or ICKDSF. Very related to the previous one is "Flashcopy for Open Environments". Another nice presentation is "PPRC Overview" discussing Metro/Mirror, Global Copy, Global Mirror, and Metro/Global Mirror. There's specific attention on how each of these maintains consistency. There's also advice on how to choose the best solution for each specific situation.

I thought another related topic, which might be of high interest these days is IBM Tivoli Storage FlashCopy Manager. I have put a small tutorial of it at IBM Tivoli Storage FlashCopy Manager tutorial
I believe this product is worth checking out when you are planning to deal with IBM DS FlashCopy as soon you start touching databases.
Enjoy,
