Re: shmget problem on solaris

You need to check into setting the following values in /etc/system

set shmsys:shminfo_shmmax = 16000000
set shmsys:shminfo_shmmin = 1
set shmsys:shminfo_shmmni = 100
set shmsys:shminfo_shmseg = 20
set semsys:seminfo_semmns = 200
set semsys:seminfo_semmni = 70

This is how mine is currently set. It probably isn't optimal but it gets
the job done. :)
