SOA is a platform neutral protocol. It can be implemented on z/OS as well as on Linux, MAC, *BSD, as well as Windows. The only "plus" of a non-z/OS platform is that there are more, cheaper, programmers on Windows et al. than on z/OS. It is easier to hire somebody with SOA and Windows background than SOA and z/OS. And those which such a background don't want to consider applying their knowledge on z/OS. I guess they're worried that we have "cooties". Also many z/OS shops seem to be "legacy oriented" and don't want to consider implementing new technologies. Well, hopefully I'm wrong, but it is definately true around here. Management doesn't want the mainframe to embrace new software technology. Neither do the programmers nor even others in my group. I'm still the only one who has any understanding of z/OS UNIX and what can be done with it (even tho it is inferior to Linux in many ways, IMO). But I cannot use it in production because "nobody else understands it". So, instead, I download stuff to my Linux/Intel box and run "ad hoc" stuff there most of the time. This gets me kudos because I don't use up "expensive" z/OS CPU. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
