Visit the Installation Manager information center at http://publib.boulder.ibm.com/infocenter/install/v1r2/index.jsp and search for performing silent installations.
To perform silent installation, you must configure a response file that contains the data required to perform the silent installation. The IBM® Rational® Project Conductor installation media contains a sample response file rpc.responsefile.xml that is available at disk1/sample_response_files. You can configure this response file by specifying your preferences.
