Windows Registry as a Directory Service

Adaptive Server Enterprise only – you can deploy an application on multiple clients and enter the network information once in the Registry on the Adaptive Server computer without creating and maintaining a sql.ini file on every client.

Adaptive Server Enterprise and its bundled applications – the client applications that are bundled with Adaptive Server require a sql.ini file. Even if you are using the Registry for your own applications, you must maintain a sql.ini file if users are to connect from any of the Sybase client applications, such as Sybase Central.
