Tha answer can be found in the Security, Performance and Accounting
Administration manual. More detail is available from the Answerbook.

The following can be put in the /etc/system file.

set semsys:seminfo_semmap=10
set semsys:seminfo_semmni=10
set semsys:seminfo_semmns=60
set semsys:seminfo_semmnu=30
set semsys:seminfo_semmsl=25
set semsys:seminfo_semopm=10
set semsys:seminfo_semume=10
set semsys:seminfo_semvmx=32767
set semsys:seminfo_semaem=16384

set shmsys:shminfo_shmmax=1048576
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmseg=6

The above values are the default values and can be increased
according to needs.

If new values are used, you need to do a touch /reconfigure and
reboot.
