I believe that documentation is telling you that each OS governs the amount of shared memory you can have in different ways. Linux, for example, has a variable called shmmax, accessible as /proc/sys/kernel/shmmax, which controls how much shared memory you are allowed to allocate. I think Solaris' setting lives in /etc/system somewhere. Cory 'G' Watson http://gcdb.spleck.net
