The question was what are the ramifications of diddling with the shared
memory parameters? That didn't really get answered, but these things did.
1) How to diddle with it.
1.1) If you just want to diddle with the shared memory, you can do so
by playing with the /etc/sysconfigtab. Shared memory is controlled by
the ipc subsystem (interprocess communication), and the variable is
shm-max. See the man pages for sysconfigtab, sysconfig, and sysconfigdb.
1.2) If you have to play with other variables that aren't accessible
dynamically, you can get at them through ../sys/conf/MACHINENAME
kernel configuration file, then rebuild the kernel. In the special
options section, add a line specifying shmmax.
1.3) Diddle with param.h. Don't. It's probably better to play with
1.1) or 1.2).
2) How to get I-DEAS to work.
Following 1.2 above, change the following variables to something like:
> dflssiz 33554432
> maxssiz 67108864
> shmmax 16777216
And rebuild the kernel.
