Ways to Provide Parameter Values

Values for PIF product parameters can be provided in different ways, as follows:

As default parameter values: The default value of a parameter is defined in the Default section of the prototype file. The default value ensures that a value always exists for that specific parameter.
From the environment: During product installation, the Installer examines the environment of the running shell. If a parameter value has been assigned on the shell, it will overwrite the default parameter value defined in the product.
From a response file: A response file, which is provided by the user to configure an unattended product installation, contains parameter value assignments that overwrite the default parameter values defined in the product.
From a script: You can define parameter value assignments in pre-install scripts (scripting parameters). These scripts insert the parameter values in the product when they are run during the product installation process.
