Read Parameter Values from the Environment

Parameters configure the installation of the PIF product. They define installation paths and include or exclude components from the installation process. Product-specific parameters can also be passed to the installation. These parameters are used inside the installation procedure scripts.

The PIF product installation resolves parameters in the following sequence:

  1. PIF parameters passed by a response file are read. The user can specify a response at installation time using the lsm command with the -r switch. Parameters collected in an installation dialog are also passed to the installation process through a temporary response file.
  2. Environment variables overwrite response file parameters in case of an unattended installation. Environment variables must be set before the PIF product installation starts.
