Just thinking about it, your DB2 is probably on prem. In which case you`d have to have network connectivity directly between databricks and your on-premise servers, which probably doesn`t exist. In which case, you`ll probably have to start looking at a different way of data ingress (i.e. a cloud data orchestator with an on-prem connector like AF). Without knowing what your architecture\tech stack looks like it`s difficult to say.
