I don't know the details, but I know our "Tandems" go into a "store and forward" mode when anything on the mainframes slows down. That could be a processor down, CICS regions down, transaction failures, dasd contention, spin loops (Ok, that one hasn't happened lately), etc. I don't see their value lessening even if their function is needed less often. I also don't think the presence or absence of parallel Sysplex (or anything else relating to type of platform) can be singled out as the villian. It all depends on application and database design, etc. It doesn't mattter how many 9s worth of platform availability (hardware, operating system, transaction processors, network, etc.) if you have to regularly take a database offline for hours. And applications can be designed poorly on any platform.
