Loga..

To change the kernel parameters through command line, u can use "kmtune" command.
Pls see the man page of kmtune for further details.

otherwise,
- extract current system file
# /usr/lbin/sysadm/system_prep -s /stand/build/system

- Modify the system file to reflect ur change

- Create a new kernel with reference to modified system file
# cd /stand/build
# mk_kernel -s /stand/build/system

- it'll create a new kernel with the name "vmunix_test" in the current direc.

- Then run the "kmupdate" command to move the kernel & system file in place while reboot
# kmupdate

Saravanan

sorry.. kmtune is for 11.11

u can use "kctune" command for changing the parameters.

Also, u can change it through web (http). From any one of the windows PC, which has a connectivity to the server, open internet explorer & type the ipaddress of the server. In that page, u'll get a option to change the kernel param.
