If you're actually interested in this, suggest you ask on LINUX-390 or IBMVM. > I also read in z/Journal that the lines between a mainframe computer (the > z10 to be specific) and a super computer are being blurred.

It means "big". And of course the T61 I'm typing this on outpowers a Cray 1 (well, maybe; not sure, but you know what I mean), so it's a moving target. As for WAS and Java and the like, that's why zAAPs exist. So I guess I don't quite grok your point. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
