As I understand it, their main objective for moving DB2 off z/OS onto z/Linux would be to save money. I don't think they know at this point if it actually would save them any money, but that's their objective. That's why my friend was wondering if anyone else has done it, and if it did actually save anything. > 2. What sort of applications access DB2? From where? (Some > shape/feel/size/number/intensity sort of information would be helpful.) I think most of their programs are written in COBOL, with perhaps a few written in Assembler, all running on z/OS. I know they use some stored procedures, but I don't know how many or what for. I'd guesstimate they have about 100 developers if that gives you some idea of size. > 3. Big databases? Growing? How big? I don't know how big, but I do know they're growing. Not be leaps and bounds, but I'd imagine a fairly steady rate of growth. > 4.

I think somewhere in the middle of that range; perhaps a little closer to missile launch control than Paris Hilton's blog . I have a feeling (but I could be wrong) that transaction speed is not a critical requirement for them. That's probably why they were originally considering moving the databases to Oracle on z/Linux, even though it would have meant going through an extra layer (which I assume must add something to the overall length of each transaction)? > I try to avoid the term "open system" since marketers have (unfortunately) > destroyed any meaning it once had (if it did).
