Aah ok :)
I've set my values now as follow (2GB RAM):
SHMMAX=`cat /proc/meminfo | grep MemTotal | cut -d: -f 2 | awk '{print
$1*1024/3}'`
echo kernel.shmmax=${SHMMAX} >> /etc/sysctl.conf
SHMALL=`expr ${SHMALL} / 4096 \* \( 4096 / 16 \)`
echo kernel.shmall=${SHMALL} >> /etc/sysctl.conf
sysctl.conf:
kernel.shmmax=708329472
kernel.shmall=44270592
postgresql.conf:
max_connections=500
shared_buffers=40000 # ~312MB, min. 1000, max ~ 83000
Hmmm - shmall set to 168G... err why? Apologies for nit picking a little
- but shmall seems unreasonably high. I can't see much reason for
setting it bigger than (physical RAM in bytes)/4096 myself. So in your
case this is 2*(1024*1024*1024)/4096 = 524288
