If the launchpad is used to start Installation Manager, the repository information is passed to Installation Manager. If the Installation Manager is started directly, you must specify an installation repository that contains the product packages that you want to install. See Setting repository preferences in Installation Manager.
Some organizations bundle and host their own product packages on their intranet. For information about this type of installation scenario, see Installing from a repository on an HTTP or HTTPS Web server. Your system administrators will need to provide you with the correct URL.
By default, IBM Installation Manager uses an embedded URL in each Rational software development product to connect to a repository server over the Internet. Installation Manager then searches for the product packages as well as new features.
