You can use the installer to set tunable parameters with an un-integrated response file. You must use the parameters described in this guide. Note that many of the parameters are product-specific. You must select the tunables that you want to use from this guide.
See Tunables value parameter definitions.
To set tunables with an un-integrated response file
# ./installer -responsefile response_file_name -tunablesfile tunables_file_name -settunables
Where response_file_name is the full path name for the response file and tunables_file_name is the full path name for the tunables file.
Certain tunables are only activated after a reboot. Review the output carefully to determine if the system requires a reboot to set the tunable value.
