New Features and Upgrading Guide
CHAPTER 4. Behavior Changes
As new operating systems and network protocols are introduced, and as older ones become obsolete, the range of platforms supported by Adaptive Server Anywhere changes.
Operating systems There are several changes to the list of supported operating systems.
Several UNIX operating systems are supported for the first time.
DOS and Macintosh operating systems are no longer supported for client or server.
No network database server is supplied for Windows 3.x (no network server). The personal database server now requires the Win 32s subsystem, version 1.30.
Not all operating systems may be made available at the same time.
Network protocols NetBIOS datagrams (NetDG) is no longer supported as a communications protocol. NetBIOS sessions are still fully supported
Programming interfaces The HLI and DDE programming interfaces are not supported in Version 6. If you have existing HLI or DDE applications that you wish to run against a Version 6 database engine, you can do so using the Version 5 HLI and DDE interfaces in conjunction with the Embedded SQL interface compatibility library included in Version 6.
For information about the Embedded SQL interface compatibility library, see Using the compatibility library.
JDBC is provided as an additional programming interface.
TCP/IP change UDP is a transport layer protocol that sits on top of IP. Adaptive Server Anywhere uses UDP on top of IP to do initial server name resolution and TCP for connection and communication after that, while SA used UDP for everything.
