That is the mechanism for SunOS 4.x.
Solaris 2.x is SVR4-ish. On Solaris you add line(s) to the /etc/system file and
See Appendix A "Tuning Kernel Parameters" of the Solaris AnswerBook
document "Solaris 2.3 Administering Security, Performance, and Accounting" for
Our Pyramid running SVR4 has a completely different mechanism.
We are suppose to be getting a AT&T (NCR) SVR4 system real-soon-now and
I wouldn't be surprised if it was different yet again.
In other words, it depends a lot on your specific incarnation of SVR4.
The other thing is deciding which value to change - there are probably half
a dozen that have to do with semaphores :-)
