Kernel OS= hp-ux 11

[Shaamil]

Is it possible to rebulid a kernel without rebooting the server.
Also can U add your own kernel parameters in /stand/system.
The OS is hp-ux 11.00

Well, you can build the kernel and postpone re-booting, but, obviously, none of your changes will take effect until you do re-boot.

What do you mean by your own kernel parameters? You can't set foobar=1. You can change legitimate kernel parms in /stand/system, though.

Personally, I always go through SAM. You can still postpone the re-boot and SAM will update /stand/system and build the kernel for you.

To answer the question Yes, you can rebuild the kernel without rebooting the server. But it's not recommended, since you may experience improper behaviour of the system. It's strongly recommended that you reboot the system after a kernel change.

You can add your parameter in /stand/system file. You need to make a copy of original system and vmunix files, then change the system file. After the file change, build new kernel from the new system file, do kmupdate and reboot the system.

The changes you made on kernel parameters will not come in to effect unless you reboot the server.

You can use kmtune to do these changes .. look at my reply on this post ..

Having said that I did a quick test on 11.0 ..
# kmtune -q maxuprc
==> shows value=75
# kmtune -s maxuprc=125
# kmtune -q maxuprc
==> shows value=125
# grep maxuprc /stand/system
==> shows maxuprc 125
Now at this point you can manually compile your kernel and reboot for the changes to take effect. So a reboot is still require.
