Trausti Thor Johannsson's response (which is currently at the top there, but might not be
later) includes "[Java] not only made Mainframe computers not die but made them very
useful."
I don't think I've ever seen anyone claim that Java saved IBM Z, nor that it's
a major use case. Yeah, it's there, but even with zIIPs and zAAPs it's not all
THAT common, is it? Or have I just been working with the wrong sort of
customers?
I have said *many* times that z/OS UNIX nee OS/390 USS nee MVS Open
Edition saved the mainframe. Of course, by "mainframe" I meant
traditional z/OS mainframe environments.
Years ago, I met Bill Schoen at an IBM TDM reception in Poughkeepsie and
shook his hand so vigorously that he probably remembers it to this day.
I told him that I credited him, more than any other individual in the
world, with saving the mainframe. If Don Ault had been there, I would
have congratulated him too. That team (I think they were in Kingston at
the time) implemented a fundamentally-crucial difference in capability
that has been leveraged over the years by TCP/IP, Java, z/OSMF, and many
other critical components. And now Kershaw Mehta and his team, standing
on the shoulders of giants, continue that great work by fundamentally
improving z/OS UNIX to support native containers.
