You have sent system information to Sun and have purchased an update management subscription. This service level expands the functionality available at the previous (basic) service level. You can use the Update Manager application for these tasks:
Managing all Solaris updates on your system
Selecting updates for automated download and installation
Receiving notification about all update dependencies
Deciding to remotely manage your system with the Sun Update Connection Hosted web application
If your update management environment includes a Sun Update Connection Proxy and your system is a client of that proxy, your client system does not need to be registered to use the Update Manager software. The system that acts as the proxy must be registered. If, however, you decide to use the Sun Update Connection Hosted web application to remotely manage your client system, that system must be registered.
