Adaptive Server version 15.0 and later contains ODBC drivers developed by Sybase. The third-party rebranded ODBC Kits included with earlier versions no longer ship.
The retired ODBC Driver Kit was installed in $SYBASE/ODBC, and registered with the ODBC Driver Manager as “Sybase ASE ODBC Driver.” The new ASE ODBC Driver by Sybase is installed in $SYBASE/DataAccess/ODBC, and is registered as “Adaptive Server Enterprise.” The version shipping with Adaptive Server 15.5 is version 15.5.0.1000.
Sybase recommends that you update your ODBC Driver to the new Sybase ODBC Driver as soon as possible. The third-party driver versions released after November 30, 2007 do not connect to Adaptive Server 15.0 or later.
See New Features Open Server 15.5 and SDK 15.5 for Windows, Linux, UNIX, and Mac OS X, for instructions on migrating to the new drivers.
