data size in ulimit

Ricky_4 — Mon, 14 Oct 2002 00:12:54 GMT

Hi All,

We would like to modify the data size in ulimit to 1Gb and its default is only 500mb. This configuration is required by the application during installation. So we used ulimit -d 1000000 but it prompts us exceeding the limit. By the way we're using K class and hpux 11.00.

Is there a way to modify the data size in ulimit and why we can't adust it to 1Gb?

Have a look at these, regarding maxdsiz:

or

$ ulimit -aS

file(blocks) unlimited
data(kbytes) 65536 max determined by maxdsiz
stack(kbytes) 8192 max determined by maxssiz
memory(kbytes) unlimited

Hi,

You have to change this in the kernel. The parameters you would have to change are maxdsize and maxdsiz_64bit. The only thing I'm not sure about is the maximum size allowed for these parameters.

Hi,

Have you tried modifying the /var/adm/cron/.proto file to resolve the ulimit warning.
Your /var/adm/cron/.proto file should contain this information:

# @(#) $Revision: 27.1 $
cd $d
if [ "$l" = "4194304" ]; then
ulimit unlimited
echo was number
else
ulimit $l
echo was unlimited
fi
ulimit
umask $m
$<

Thanks
