You must provide a URL that identifies the Rational Synergy CCM Server. This location is where the installation is served. The URL has the format: http://ccm_server_host:ccm_server_port/install.html, where
primary_ccm_server is the host name of the server where the server is installed, and primary_ccm_port is the port number of the server.
These are items 16 and 17 in your installation worksheet.
The CM administrator must provide the URL to users who perform the Client installation by downloading it.
