server_name unique replication server name of publisher
(specified in [Replication] -> [ServerName] section in ini file of publisher).dsn data source name of publisher.replication_address host:port pair of publishing server where this subscriber will connect to.
This function defines a server that will participate in replication.
The name is a symbolic name that should match the name specified
as the ServerName configuration parameter in
the replication section of the virtuoso.ini file of the server being defined.  The address is the <host:port> where the
server designated by the name is listening. The DSN is an ODBC data source name referring to the server, so that the subscriber can retrieve schema and other information.  Note that replication communication itself does not take place through ODBC but that ODBC access to the publisher is required to initiate the subscription. In order to subscribe to
publications from a server the server must first be declared
with this function.  If this function is called to define the local server, i.e. the given server name is the ServerName in the Replication section of the local ini file,  an error is signalled and the function has no effect.
