ECDA Option for ODBC requires ODBC drivers to provide connectivity to the client and to the target database.
Sybase ships an ODBC driver with ECDA to provide ODBC connectivity to ASE/CIS. The same driver can also be used for connectivity to Mainframe Connect. See the Mainframe Connect Overview Guide for more information.
Sybase no longer ships ODBC drivers for non-Sybase databases. Instead, you obtain the necessary ODBC drivers for DB2 UDB and Microsoft SQL Server.
For the ECDA Option for Oracle, native Oracle OCI connectivity is provided.
