Do I need to install any software on the local system to use Sun Update Connection, System Edition software, or can I manage updates only from the hosted web application?
You must install the Sun Update Manager client software on each client system where you want to manage updates. This software enables you to manage updates locally on a system. You must install this software on any system that you want to remotely manage. If you want to configure a Sun Update Connection proxy, you must install the Sun Update Manager software as well as the proxy software. For more information, see “Installing the Sun Update Manager Software” in the Sun Update Manager 1.0 Administration Guide.
