NFILE

[Shoghi_1]

Hello everyone!

I was having problems with the OS file table so I change the system parameter NFILE with :

kmtune -s nfile=40448

After I rebooted the server and I query the parameter with kmtune -q nfile I get the parameter I just entered (40448) but when I use sar -v 1 5 I get the old value (16394)

Did I make something wrong?
Do I need to do something else?

Thanks to all!!!!

Hi Shoghi,

Did you rebuild the kernel & move it into place?

mk_kernel -o /stand/vmunix

HTH,
Jeff

Hi Shoghi,

Can you run the following command and print the output? :

# echo nfile/D|adb /stand/vmunix /dev/kmem

The kmtune command will only query the system (or applicable) files, not the kernel. Did you rebuild the kernel and update it? Also, please mention the OS you are using - HP _currently_ support about six versions and from these three different ways to generate kernels.

Cheers,

James.

did you seen the new entry in /stand/system?

If not add it, then run

mk_kernel -o /stand/vmunix & then reboot

Thanks!!!!!!!!!!!!

I think the step I'm missing is to rebuild the kernel.

I will try doing it.

Hi

you can use SAM to rebuild the kernel nice and easy

after you make the kernel - don't forget

kmupdate - on hp 11, or (use SAM to mod your kernel)


on hp10.20 -
mv /stand/vmunix /stand/vmunix.prev
mv /stand/build/vmunix_test /stand/vmunix


reboot required in both.

In 11 - you can use kmtune to dynamically bump the value of the parameter.
