[SunRescue] RE: mainframes in our midst...

[Ken Hansen]

Jon,

Mainframes were "partionable" (on a hardware level) over 10, maybe even 15
years ago.

is a very good, solid operating environment, that enabled multiple OSs to
run on one processor complex (in the mainframe world, CPU maps to a box the
size of a commercial refrigerator) at the same time (and PR/SM allows you to
run multiple machine code levels ont he same machine, allowing you to try
out new microcode for the CPU without needing a "test" machine, all you need
is a test "partition"), and CICS, is well, quite efficient.

mainframe can do things that are simply absurd on the departmental server
level, and the overhaed involved in working in a mainframe environment is
equally absurd for a departmental server. Each has it's place.
