Jim,
this is copied from /etc/rc...
\
if [ -f /etc/sysctl.conf ]; then
awk '{ if (!index($1, "#") && index($1, "="))
print $1 }' < /etc/sysctl.conf | while read
do
sysctl -w ${REPLY}
done
fi
sysctl -w kern.sysv.shmmax=4194304
sysctl -w kern.sysv.shmmin=1
sysctl -w kern.sysv.shmmni=32
sysctl -w kern.sysv.shmseg=8
sysctl -w kern.sysv.shmall=1024
this is copied and pasted from my /etc/sysctl.conf:
kern.sysv.shmmax=33554432
kern.sysv.shmmin=1
kern.sysv.shmmni=32
kern.sysv.shmseg=8
kern.sysv.shmall=65536
here is my responce from the terminal
postgres$ sysctl kern.sysv.shmmax
kern.sysv.shmmax: 33554432
postgres$ sysctl kern.sysv.shmall
kern.sysv.shmall: 65536
It looks like my settings in /etc/sysctl.conf are
sticking just fine
