A file name sql.ini must be present in the %SYBASE%\ini directory. This file contains server entries for each server in the network known to your system
To modify the sql.ini file for a new server, use the dsedit utility that is supplied with Open Client and Open Server. Using dsedit, enter the new server name, the TCP/IP host and port number.
For documentation on dsedit, see the Open Client and Open Server documentation.
In order for the server to start, the server name and
the configuration file name must be the same.
