server_name - SERVER_URL option

The server name refers to the name or the TCP/IP address of the server machine, where the server is running.

Usually, this value is set in the configuration or ini-file in the SERVER_URL option for the data source definition, but it might also be defined as global option variable.

When a SERVER_URL option variable is defined, dictionary and client are accessed via server (object or replication mode). In order to use a local dictionary or database, instead, DICTIONARY.CONNECTION=local or DATABASE.CONNECTION=local has to be defined.
