Current value for Kernel parameter

OLIVA_1 — Wed, 13 Sep 2006 09:22:27 GMT

Hello,

I would like to know which is the current value for a kernel parameter for instance "maxdsiz".
I would like to know the real value not the set value....

Because I have the error message :
xcalloc: Unable to allocate 4096 blocks of 1 bytes

generated by Squid
My OS is HPUX 11.00

Thanks for your help.

# kmtune -q maxdsiz

This will achieve what you need.

kmtune -l -q maxdsiz
Should give you what you are looking for.
Unless I misunderstand your question.

Hi

/usr/sbin/kmtune -l -q maxdsiz
l - prints a detailed report;
q - query the value of specified system parameter.

Cheers,

Squid is not a big memory user by today's standards, perhaps a hundred megs or so. maxdsiz only has one value -- the one reported from kmtune. The default is 64 Megs (far too small for almost any big program) so change it to 1500 Megs. Squid won't come close to using that value. But maxdsiz is not the only limitation. Now check that ulimit is not set to limit memory usage. Type the command:

ulimit -a

to verify that memory is unlimited (which means up to maxdsiz). NOTE: You must be logged in as the Squid user to view the ulimit setting in case ulimit is different for other users.
