Is Open Server part of ASE or SDK?
No. Open Server is a separate point product which is not included with ASE or SDK. If you wish to develop Open Server-based applications, you must purchase this product. Open Server contains the Server-Library and Client-Library components, in addition to the Connectivity Utilities such as isql, bcp, dsedit, and so on. It does not contain DB-Library, ESQL/C, ESQL/COBOL, jConnect or the .Net Data Provider for ASE.
