DB2 Connect is not included with any DB2/400 component.
The DB2 Connect component is available as a separate product (DB2 Connect
Personal Edition, Enterprise Edition, Unlimited Edition, Application
Server Edition), but also does come with DB2 UDB ESE. However ... the
license that comes with DB2 UDB ESE is limited to a certain # of
concurrent users (I think it's 5 but I'm not sure). If this is the way you
choose to implement it, you'd need to check with your local IBM rep.
