Hi Louis,
There is a Solaris Tunable Parameters Reference Manual available at:
http://docs.sun.com:80/ab2/coll.707.1/SOLTUNEPARAMREF/@Ab2TocView?Ab2Lang=C&Ab2E
nc=iso-8859-1
It will describe what these mean. All of these are valid Solaris variables.
Basically the msgsys values refer to the msg IPC layer. The semsys values
refer to the semaphore IPC layer. The pln, soc, socal and fcaw variables refer
to settings in various device drivers. The tune_t variables are solaris tuning
variables.
See the above manual for more information.

>On Solaris, I've heard that it isn't a good idea to fool around
