Hello Alan, I would like to come back on your statement: <snip> It's certainly interesting from an academic perspective, but it doesn't meet the needs of business. </snip>
I would really like to understand IBM's view on this issue. Is it from a business point of view that Windows or Intel (x86) is not considered as a serious environment for running mission critical applications?? Unfortunately there are hundred thousands of applications out there that exist only on Windows and unfortunately not on Linux. And even when they would exist on Linux it does not mean that they would run on z/Series. So since long time I wonder myself what is the reason to simply ignore the fact that in a lot of organisations consider the costs of z/Series compared to WinTel Servers as terrible high and then this platform does not run Windows applications. (I do not want to discuss if this is true or not but this is what I hear from my management). I have all the time problems with my management to justify the costs. If x86 programs would run naively also on z/Series I would never had such problems any more. So I would see indeed a urgent need in solving this issue.
