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
WARNING: The automatic 'backup' configuration currently contains the
configuration that was in use before the last reboot of this
system.
==> Do you wish to update it to contain the current configuration
before making the requested change? y
* The automatic 'backup' configuration has been updated.
* The requested changes have been applied to the currently
running system.
Tunable Value Expression Changes
maxdsiz (before) 1073741822 1073741822 Immed
(now) 1073741824 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
