Descriptor tables on Sun sparc systems under 4.1.1

[James Biard]

I am working on a project that requires a Sun 360 to have a larger than
standard number of files open concurrently in the system.  As a result, we
are going to have to configure the kernel to have a larger system descriptor
table.  My question is, for those who are in the know about Sun kernel issues,
is the only safe way to increase the table size by increasing MAXUSERS, or
can I edit the param.c file and set the variable nfile to, say, 1024, instead
of the formula based on MAXUSERS.  My concern is that I don't know how
interrelated the different kernel structures are, so I don't know if upsizing
the descriptor table requires upsizing other portions of the kernel that
would not be upsized if I made only the change to nfile.  If someone could
reply to me directly at

I would appreciate it, since I don't subscribe to either of the digests that
this message is going to.
