You created an ODBC data source, but no longer have the underlying native connectivity software or environment.
Reconfigure the native connectivity environment and then run the session.
A session with DB2 UDB EEE sources or targets failed when the Integration Service ran on AIX and used both the DataDirect ODBC driver manager and the DB2 UDB EEE CAE ODBC driver. This problem occurred because the DataDirect ODBC driver manager and the DB2 UDB EEE CAE ODBC driver are not compatible.
Do not use an ODBC connection. Be sure to only use a native DB2 CAE connection to a DB2 database.
