Others have suggested a good start of display commands,
IPLINFO, SHOWZOS, etc. This is a good way to compare
running systems because the output will be in predictable
order and format. BUT....
Most parms can be overridden by commands. If/when a system
is IPLed, it will revert to the parms as specified in
parmlib. If you have proper change control, those parms
have been updated, too. But, if you had that level of
change control, you probably would not be in the situation
of trying to compare parms from one system to another.
So it probably does make sense to start with the easy
techniques, but you may still have to slog through checking
the parmlibs against each other the hard way.
But I have two thoughts on the above:
Do you have a sandbox where you can IPL those systems in a
test mode and compare the displays with the running
systems?
Are there (supported?) ways to generate parmlib members
from what's actually in effect? (ISTR that JES2 does.) If
so, they'll probably be in he same formats and orders, thus
easy to compare.
