Q: Setting kernel parameters permanently sysctl
Hello Folks,
I want to install the PostgreSQL 9.0 on my MAC OS X 10.6.7
now the basic requirement for the installation is that the shared memory is
kern.sysv.shmmax=1610612736
kern.sysv.shmall=393216
kern.sysv.shmmin=1
kern.sysv.shmmni=32
kern.sysv.shmseg=8
kern.maxprocperuid=512
kern.maxproc=2048
Now tried changing these parameter by editing the /etc/sysctl.conf file
but the issue is when I reboot the kern.sysv.shmmax values is not the same.
How can I set the kern.sysv.shmmax value once and for all?
