Createing a remote UDF for a Federated DB2 LUW 9.5 database

There are a couple good references for federated DB's that I've found in my research, but none really laid out the high level process for connecting a DB2 federated DB to a UDF on a data source.

Here are the steps.

  1. Create Function on Datasource DB
  2. Create Function Template on Federated DB
  3. Create Function Mapping on federated db



For details on how to perform each of these steps, consult

  • The DB2 9.5 Info Center. There's an entire section on Federation that's OK.
  • The Federated Systems Guide. Google it. It's a PDF.


Good luck!
