Hi All,
Just wondering if anyone new about documentation as how to change kernel parameters without using SAM.

Thanks All

Hi:

You can do this with 'kmtune'. See the man pages for more information.

Simlpy use a script to create you /stand/system file to what values you want then build the kernel. If it builds ok then youre done.

Use the /usr/lbin/system_prep command to first create your new /stand/system file from the currently running kernel, then edit it as required, then build the new kernel.

You can change the values with "kmtune" command. Read man pages of:
# kmtune
# kmupdate
# mk_kernel
# config

etc.

# mv /stand/vmunix /stand/vmunix.prev
# mv /stand/build/system /stand/system
# mv /stand/build/vmunix_test /stand/vmunix
# shutdown -ry 0

For 11.x
========
