Hi there,

for an Oracle installation we need to set the SHMMAX parameter up to 32GB.

SLES default parameter is 4GB
#> ipcs -l
max seg size (kbytes) = 4194303

When I try to set /etc/sysctl.conf parameter to 32GB ipcs shows 0.

#>cat /etc/sysctl.conf | grep shmmax
kernel.shmmax = 34359738368

After a reboot ipcs shows
#>ipcs -l
max seg size (kbytes) = 0

But sysctl -p shows the right value
#>sysctl -p
kernel.shmmax = 34359738368

Do we have a problem here ? Why shows ipcs a zero value ?

Thanks a lot !
