Yes, it is set by ulimit shell builtin or the ulimit system call.
This is standard System V, but on most systems it is set very high.
You have to be super user to increase it, but anyone can decrease it.
IBM has also add other things you can set with ulimit.  I would guess 
that this value is set in /etc/master which would mean that you 
would have to relink the kernel to change it but it not that big of 
deal to do.
