Many thanks for the help. I just changed the value in the /etc/system file and rebooted,
showed the boss it had changed, and changed it back. Took a little explaining for the second
reboot, but oh well.

Here is my original message:

Hi all,
        The boss read a magazine that told him to increase the number of TCB's
on our web server to increase performance. SO, I get to figure out what
that means and how to do it. I do know that TCB's are Transaction
Control Blocks, and that on solaris systems the number of them is
controlled by the MAX USERS system varible. I just can't remember how
to set that varible (I forget commands as easily as I do birthdays.)
Our web server is a Sun Ultra 1 running Solaris 2.5 with the 2.5 jumbo
patch. Any help would be appreciated. Thanks -- I will summarize.
