When connecting to a cloud database server, specifying a server name on the connection string is only allowed for NODETYPE=DIRECT. When using other NODETYPE values to connect to a cloud database server, specifying the server name is not allowed. Typically, for connections to a cloud database server the HOST connection parameter or HOST protocol option is used to specify the address of one or more cloud database servers.
