maxuser - kernel tuning solaris 8

Hi all

Seem to have a concurrent processes issue on a server of mine. At peak times, the application vendor reckons we need to up the amount, as it is reaching its limit and preventing any more processes.

Looking in /etc/system, nothing has been set, so server is running with default levels.

been searching the net, and have sort of figured that setting maxusers correctly, will inturn update all other paramters, including the number of processes. Reading sun's docs / internet manuals / user views, I should set the maxusers to the amount of physical memory, aka ive got 24576Mb.

How does this sound to you experts ?

Currently, my server has 2048 for maxusers

mdb -kw; maxusers/D shows me 2048

So, Im planning to enter "set maxusers=24576" in to /etc/system. but, should I then leave the kernel to then calculate the other parameters accordingly ? or should I also add enteries for them too e.g. max procs, max_nprocs etc etc.

some advice would be gratefully appriecated :0)
