There's a huge gulf between what the platform is capable of and what people actually do with it. <SNIP> Perhaps if you stop and think about it for a few moments, the shops that stop and do all these batch updates (or come to a halt for 30-90 minutes) are the shops that seem to be able recover quickly during a Recovery practice. The ones that run 24x7 with no daily sync-point (across all systems) find that when they are forced to do a D/R practice, they have n number of platforms in various states (looking at a business day), and then realize that they have a secondary disaster on their hands. Meanwhile, continuing to think about the aforementioned situation (running in '85 compat mode), yes, there are things that can be done to allow real-time updates using VSAM. But when has a good business case been presented to upper management to go to that kind of processing? Understand, with a Bank, that may be forbidden by law (debits first processing being illegal...).
