Ok, it seems that Informix is a bit behind the times as far as Tru64 is
concerned. The two things they want changed in the /sys/conf/SYSTEM-NAME file
are not changed in that file. These days, all you need to do to change maxvas
(aka vm-maxvas) is change the max_per_proc_address_space under the proc:
subsystem, and to change the maxdsiz you change the max_per_proc_data_size under
proc:. Changing the sysconfigtab file and rebooting is the only recommended way
to change kernel parameters, and you don't need to rebuild the kernel.
Big thanks to Dr. Tom, and Johan Brusche.
