hpux dynamic or static kernel

[Shivkumar]

Dear Sirs,

Whether the kernel of hpux 11i is static or dynamic ?

What are the criteria to classify unix kernal as dynamic or static ?

Thanks,
Shiv

All versions of HP-UX 11i support both static
and dynamic kernel modules.

I guess you could say it is a little of both.

There are some kernel parameters that can be modified dynamically, which means you can change them, they take effect immediately, and you don't have to reboot the machine.

But there are still some kernel parameters that are static, meaning you have to modify the parameter, generate a new kernel and reboot the machine before the value will take effect.

Hi,

Some of the kernel parameters are static and some are dynamic. To find our if a particular parameter is static or dynamic, you can use kmtune to query system parameters

eg:-

kmtune -q nfile
Parameter Current Dyn Planned Module Version
===============================================================================
nfile 7822 - (16*(NPROC+16+MAXUSERS)/10+32+2*(NPTY+NSTRPTY+NSTRTEL))

Shiv,
just issue the command kmtune and the output will tell you if a given kernel parameter is dynamic or not.

The criteria for being static or dynamic is something to do with the design of the kernel and how the modules plug in.

thanks
