You need the data source name (DSN) values for each ODBC target when you set up connectivity for ECDA.
Sybase does not ship ODBC drivers with ECDA to provide connectivity to non-Sybase target databases. You must obtain a separate driver from IBM, Microsoft, DataDirect, or other vendors, for the ODBC driver that is needed on the particular platform where ECDA is running.
Do not continue installation until connectivity is running successfully between the machine that hosts the DirectConnect server and the target database.
