You can set non-default product and system tunable parameters using a tunables file. With the file, you can set tunables such as the I/O policy or toggle native multi-pathing. The tunables file passes arguments to the installer script to set tunables. With the file, you can set the tunables for the following operations:
When you install, configure, or upgrade systems.
# ./installer -tunablesfile tunables_file_name
See Setting tunables for an installation, configuration, or upgrade.
When you apply the tunables file with no other installer-related operations.
# ./installer -tunablesfile tunables_file_name -settunables [ system1 system2 ...]
See Setting tunables with no other installer-related operations.
When you apply the tunables file with an un-integrated response file.
# ./installer -responsefile response_file_name -tunablesfile tunables_file_name
See About response files.
You must select the tunables that you want to use from this guide.
