Original question:
********************************************************************************
I need to increase the amount of shared memory a process is allowed to use.
The Solaris FAQ says to add a line like the following to /etc/system.
set shmsys:shminfo_shmmax = <value>
Does <value> represent the # of bytes like my Digital Unix systems?
Is there a way to increase for a particular user or can I only do it
on a system-wide basis?
Is there a tool that will show me parameter settings for the kernel modules
that are loaded?
How can I show the amount of physical memory on my system from Solaris?
Thanks for any help.
Ernie

Yes.
See docs.sun.com for compleet descriptions of these parameters.

No, system wide only.

sysdef will show you once the modules are loaded.
sysdef -i shows the main current kernel parameter settings.
www.sun.com has links to documents on kernel parameter tuning and manipulating
shared memory.

Check out the following tools:
ftp://usc.edu/pub/sysinfo/sysinfo-3.2.2.tar.gz
ftp://ftp.ece.uc.edu/pub/sun-faq/Utils/whatami.sh
OR
prtconf
prtconf -v
/usr/sbin/prtconf | grep -i mem or dmesg | grep -i mem
OR
If your Solaris architecture supports its, usr/platform/sun4d/sbin/prtdiag
is a good tool to show the amount of RAM you have installed.
