You can install a product package silently by using either Installation Manager in silent installation mode or by using IBM® Installation Manager installer. When you run Installation Manager in silent mode, the user interface is not available; instead, a response file inputs the commands that are required to install the product package.
The Installation Manager information center contains the most up-to-date information about using Installation Manager to silently install the product. Visit the information center for Installation Manager at http://www-01.ibm.com/support/docview.wss?uid=swg27010911.
