4.2.2 Installing with a Response File
Many Oracle software products provide tools and procedures for running OUI from the command line without displaying OUI screens or responding to questions during the installation.
This is called silent installation.
Instead of prompting you to select a series of installation
options, OUI installs the software using a predefined set of
options. These options are stored in a response file
(.rsp).
Note:
If you attempt to perform a silent installation on a UNIX computer where no Oracle products have been installed, you will receive an error message. Before you can perform a silent installation in this situation, you must first run theoraInstRoot.sh script located in the oraInventory directory. You must run this script with root privileges. This enables OUI to set up the Central Inventory on a clean host.
