Dynamic Kernel Parameters

[Paddy O'Connell]

Hi,

Can someone please confirm for me that if i change a dynamic kernel parameter, the change is actually keep after a system reboot?

In case you need the info the kernel parameter i'm changing is maxfiles_lim.

Thanks
Paddy

Paddy,

The new kernel parameter is kept after a reboot.

hi,

for dynamic kernel para., its value can be changed without a reboot unlike static para., whose value cannot be changed witout rebooting the system as a kernel rebuild is required.

Hi,

All parameter changes are stored in files which lies in /stand directory and are scanned during bootup. The difference in static & dynamic is that dynamic do not require reboot whereas static requires a kernel rebuilt and hence reboot.

HTH,

Yes. It will be getting effect after reboot.

If you want to know the value of parameter then,

use kctune ( 11.23 > on wards)
kmtune -q (11.23 <)

use same for getting kernel parameters.

hth.
