Program document & console command to limit sessions

I have searched and found various syntax methods…

I want to limit user sessions while compacting databases by issuing a console command from a Domino program. In the program document I have the following:

Program name: nserver

Command Line: -c server_restricted=1 update

I tried these cobminations:

nserver -c server_restricted=1 …not recognized

nserver -c server_restricted=1 update …not recognized

I was also told to use quotes around the command, but that didn’t help.

Should I be using ‘Set Config’ or some other combination? If you have the answer, please illustrate the exact syntax.

Thanks for any help…
