Oracle GoldenGate gets the name of the database it is supposed to connect to from the SOURCEDB parameter. To configure the connection for the SOURCEDB parameter, use the following format:

SOURCEDB dbname@hostname:port, USERID mysqluser, PASSWORD welcome

The dbname is the name of the MySQL instance, hostname is the name or IP address of the MySQL database server, port is the port number of the MySQL instance. If using an unqualified host name, that name must be properly configured in the DNS database. Otherwise, use the fully qualified host name, for example myhost.company.com.
