Re: Kmtune help.

Dear FTP Denied,
Use kctune to change kernel parameter values in HPUX (kmtune is a wrapper and it in turns call kctune).

kctune parameter=value

For e.g.
Say to change the maximum size of data segment,

# kctune maxdsiz=1073741824

Re: Kmtune help.

....and which parameter??
Because some parameter required rebuilding of the kernel.
Also if you can reboot the server,make changes in /stand/system file and rebuild the kernel.
Don't forget to keep a backup of current system file and /stand/vmunix
