Troubleshooting Top Updates in HCL Connections

Orient Me shows Top Updates on the startpage of Connections, but sometimes this view is empty, how is this generated? Last week, I had three systems with issues displaying the Top Updates in the Orient Me. So I tried to find out which applications and containers are involved in generating the content for this view. First, we need to know that Top Updates are part of the Component Pack, and the content of Latest Updates is the Activity stream data, which is read from the homepage database. If the Top Updates tab is not visible after deploying the Component Pack, check LotusConnections-config.xml; the serviceReference for orientme needs to be enabled. There is only one serviceReference allowed for an application in this file, so check for duplicate definitions when the tab is still missing.
