you can either add these parameters follwing the examples of any existing parameter for the file syntax and proceed with your kernel compilation, but looking at the question, please do not take it as denouncing your skills, you seem to be a little new to HP-UX, in which case I suggest the use of sam to make the kernel parameter modifications. This will protect you against a fatfingering and rendering your system useless for a while.

You shouldn't edit the system file directly. In your case, I would use SAM->Kernel Configuration->Configurable Paramteters

Select the desired tunables and modify them. Next choose Actions->Process New Kernel.

This will do all the steps involved in building a new kernel and keeping a safe bootable copy.

Now, after i have done that where will be the old system and vmunix files be. I mean if i have to reboot from the old copies what will be their path...
/stand/vmunix.old i assume !!!

Thanks

close but not quite. The "prev"ious kernel is found at :

/stand/vmunix.prev

Hope this helps
