I looked into this yesterday and the problem is that the managed connection information does not tell what database driver to use. Yes, it says DB2_DRV but that is the DataFlex Connectivity kit and not the ODBC driver "IBM DB2 ODBC DRIVER" or something like that. That means you better add DSN to the connection information or build up the connection string with the connection string builder in v6.2 and v7.0.
