In The Raiser's Edge, users can view the Database Connection Viewer under Plug-Ins. This shows the users who are currently connected to the database. Sometimes, the same machine name will be listed multiple times in the Database Connection Viewer, and this solution explains what that means.
These are the connections The Raiser's Edge makes to the database during a process (such as an export, query, etc) to gather information from database tables. This process does not use multiple database user licenses.
