Well, Domino *is* available on z/OS, but it's: a) a rather heavyweight product in terms of care and feeding and footprint b) it's a CPU hog if you have extensive custom scripting (LotusScript assumes that CPU is not a resource that needs conservation, but bandwidth and disk I/O are, mostly due to it's Intel roots) c) hard to scale -- MVS thinks best with small numbers of images doing lots of work; Domino is architected for larger numbers of images doing small amounts of work. Item C is one of the major reasons why many of us want Domino on Linux for 390. In terms of application architecture, it's a natural fit for Linux in virtual machines, and most, if not all, the hard work to make it work that way is already completed. Much of the discussion I've heard about Domino on Linux appears to be that it performs poorly with large numbers of users -- well, split them up into multiple server images, take advantage of the backplane network to do replication of common data, and _keep the images small_. Sounds like a perfect match for Linux in virtual machines... -- db
