Hi Everyone,
I've been looking into the Maxusers parameters on all of our
systems and never considered 1024... We have 100+ interactive users on
one system with Maxusers at 128. Another system has a Maxusers parameter
of 256 with approximatly 52 gigs of data, no interactive, and approximatly
200+ people nfs mounting their home directory throught the use of the
bwnfsd. From what I understand you can't hurt the systems performance
through upping maxusers unless it is grossly overstated. I'm curious to
know if you take a performance hit as a result of upping it to 1024...
Unfortunatly I can't seem to find any literature with examples to specific
setups that you can use to make an educated guess. Any suggestions?
Thanks! (both systems are dec 3000/600 with 128 meg of ram)
See Ya!
BTW: Does anyone know of any books specific to Digital Unix? Does
Digital itself sell any good ones?

First I thank all the people who answer to the questions.
the os was 3.2D
The answers :

You have to increment the "pseudo-device pty" value in the
/sys/conf/mips/<MACHINE> file and rebuild (and reboot) your kernel. The new
devices you made are not seen by your kernel.
anyway, there are a few things you want to do.
1) more more ptys.
-- su - root
-- cd /dev
-- ./MAKEDEV pty3
-- ./MAKEDEV pty4
-- ./MAKEDEV pty5
2) recompile the kernel. up maxusers by a lot. (it's not actually a
measurement of users, but a number used to then calculate various
resource allocations).
I have maxusers set to 1024. we typically have 40-60 simultaneous
users, as well as a bunch of other processes.
3) install the new kernel and reboot
this should solve your problems.
good luck,
Jason

Try this:
# cd /dev
# ./MAKEDEV pty2 (not PTY_2)
It'll work fine.

Bonjour,
Il faut que les ptys soient contigues. Il faut donc faire un
MAKEDEV PTY_1 afin d'avoir la suite des pty0 et pty1 crees a l'install
du systeme.
CF: /dev/MAKEDEV
.
.
PTY_1)
devlist="$devlist pty0 pty1 pty2 pty3 pty4 pty5 pty6 pty7 pty8 pty9
pty10 pty11 pty12 pty13 pty14 pty15 pty16 pty17 pty18 pty19
pty20 pty21 pty22"
