Kernel Question

Andre Lemon — Tue, 19 Dec 2006 14:45:13 GMT

I made some changes to a few parameters in the Kernel. And after rebooting the system, I see that the changes did not affect the "Current" column but the values in the "Planned" column do show the new values.

Why? Did something go wrong?

you need choose process the new kernel and choose reboot in SAM.

Make sure you issued a 'mk_kernel' and 'kmupdate'.

But now that your here, diff the /stand/system and system.old files for diffeences and 'ls' for time stamps.

Andre,

Here how it should be, (Looks like you missed the mk_kernel portion.)

--
change the values of the parameters,

maxfiles 60
maxfiles_lim 1024
maxusers 100
maxvgs 16
msgseg 2048
msgssz 128
nflocks 4096
npty 200
nstrtel 200
swchunk 4096
vps_ceiling 64

1.# kmtune -s maxfiles-60
# kmtune -s masfiles_lim=1024
....

2. # kmtune -q maxfiles
( To check current value and planned value.)

3. # ./mk_kernel

4. # ./kmupdate

5. # shutdown -r -y 0

6. After reboot verify the kernel paramters:
# kmtune -q maxfiles.

Hope this will help,

Cheers,
Raj.
