Hi,

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

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.

regards.

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.
