The Distributed Data Facility (DDF) is a component of your IBM database. Its primary task is to route data from one database to another or from a client to another client (distributed unit of work). If distributed data has never been implemented, it may not be configured. Refer to the DB2 Administrator for the state of the component. The key information required for StarSQL is the RDB name and the LUNAME. You can find these names by running the VTAM change log inventory utility or through panels by using DSNTIPR. The line will look like this:

--->DDF LOCATION= locname, LUNAME=REMTLU(PASSWORD=....)
