The configuration in this case is a Dimensions Server hosting the database, a client node hosting libraries (a DFS client) and a normal client (for example just a PC with CD2 installed).

Check the file $DM_ROOT/dfs/email_config.dat on the Dimensions Server installation. Ensure that the databases listed are valid Oracle databases that can be connected to using for example Sql*plus. If any of the entries point to Oracle database connections that are no longer valid, then comment out these lines using the # character at the beginning of the line and restart the listener.
