Some applications do not connect to Adaptive Server directly through the Open Client software but through the Open Database Connectivity (ODBC) driver, or the jConnect driver instead. For example, PowerDynamo connects through the ODBC driver.
ODBC and OLE DB require the Microsoft Data Access Component (MDAC). You can download it directly from Microsoft's Web site http://www.microsoft.com/data
See Configuring Adaptive Server Enterprise for your platform for more information.
