Correct, try
Add the following lines to the /etc/system file to modify the
parameters. Then Reboot the system for the parameters to take
effect.
set shmsys:shminfo_shmmax=268435456
set semsys:seminfo_semmap=256
set semsys:seminfo_semmni=4096
set semsys:seminfo_semmns=4096
set semsys:seminfo_semmnu=4096
set semsys:seminfo_semume=64
set shmsys:shminfo_shmmin=100
set shmsys:shminfo_shmmni=500
set shmsys:shminfo_shmseg=100
