Re. Kernel Parameter - 'Max. num. of system processes'

Thanks to everyone who responded. I got a number of excellent tips. I found the explanation by Dr. Thomas P. Blinn very useful and informative. Here it is for the benefit of others who may be interested.

Dr. Thomas P. Blinn wrote -

"There is no "maximum number of system processes" on Tru64 UNIX. The reason
for having such a parameter would be to pre-size some table of process info
and Tru64 UNIX simply doesn't work like that. There is a quota system for
use of process resources that's done on a per-user basis, that's the limit
of max_proc_per_user and that might be what you need to set depending on
what the application really is doing and needs."

Hello! I need to tune some kernel parameters but cannot find what 'Max.
num. of system processes' is called on Tru64. The application vendors
documentation ( + 'Tru64 - System Configuration and Tuning' manual) has
not been useful. Any help or pointers would be appreciated.

Just FYI - After much digging around I was able to match the description
with the parameter name for the following -
- Max. num. of user processes --> max_proc_per_user
- Max. num. of system users --> maxusers
- Max. num. of per-process open files --> open_max_soft + open_max_hard

Thanks, Mathew
