System Tunable Parameters

[Frank J. Henigman]

Chapter 8 of the Iris-4D Programmers Guide Volume II Version 1.0, the chapter
on inter-process communication, mentions "system tunable parameters."

These parameters set limits on various aspects of inter-process communication.

My questions are:  where are these parameters documented in full and
how does one change them?  Do you need source to do it?  Thanks in advance.
