In our system which was pretuned by Oracle before delivery we have the following in our /etc/system file:

....cut....

forceload: sys/msgsys
forceload: sys/shmsys
forceload: sys/semsys
set shmsys:shminfo_shmmax=16777216
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmseg=10
set semsys:seminfo_semmns=200
set semsys:seminfo_semmni=70

set semsys:seminfo_semmsl=50
set msgsys:msginfo_msgmni=100
....cut....

Hope this helps!
