Setting tunables with an un-integrated response file

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.


Certain tunables only take effect after a system reboot.

To set tunables with an un-integrated response file

  1. Make sure the systems where you want to install SFCFSHA meet the installation requirements.
  2. Complete any preinstallation tasks.
  3. Prepare the tunables file.

    See Preparing the tunables file.

  4. Copy the tunables file to one of the systems that you want to tune.
  5. Mount the product disc and navigate to the directory that contains the installation program.
  6. Start the installer with the -responsefile and -tunablesfile options.
    # ./installer -responsefile response_file_name -tunablesfile 

    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.

  7. 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.
  8. The installer validates the tunables. If an error occurs, exit the installer and check the tunables file.
