Informatica dropped support for the DataDirect SQL Server Legacy ODBC Driver file
DWmsss27.x
because DataDirect no longer supports this driver. After you upgrade, existing ODBC connections that use the DataDirect SQL Server Legacy ODBC Driver file
DWmsss27.x
fail. You must use the DataDirect 8.0 New SQL Server Wire Protocol packaged with the Informatica installer, or any ODBC driver from a third-party vendor.
