Hi, and welcome!
Can you provide more details about the problem? Are you exporting your data from Access then trying to import it into DB2? Are you connecting the two with ODBC? Is this a one-time requirement, or are you going to need to repeat this import on a regular basis?
While not specifically what you're trying to do, the article by Paul Zikopoulos
DB2 9 and Microsoft Access 2007 is worth a look.
