2.3.3. Synchronizing Your System Profile

If you configured the Red Hat Update Agent to install the latest packages, the System Profile stored by Red Hat Network is updated after the packages are installed. However, if you only download the latest RPM packages using the Red Hat Update Agent, download the RPM packages from the website, or upgrade/install/remove RPM packages yourself, your System Profile is not updated automatically. You must send your updated System Profile to the RHN Servers.
To synchronize the RPM package list on your local system and on Red Hat Network, run the command:
up2date -p
After running this command, your RHN System Profile reflects the latest software versions installed on your system.
