Solaris 10:

If you want to count number of processes in the Interactive class
casued by interactively logged on users.

ps -elc | grep IA | wc -l

Default number of user procs is 29.995
youll need a 100 MB Ram per user
each JDS user will run an average of 35 processes

29995/35 = 857 users *100 MB = 86 GB Ram

therefore the smallest machine where this can become a concern
is a SunFire 2900 with 12 ultrasparc IV CPU and 96 GB ram.

This is wrong, as most of the memory allocated would be pointing to the same
phsyical mapped pages hense shared.

How to check the number of "user processes" in the system?
