SVUB,x: the Unified Broker Server Option
When x=0 (or when this parameter is unspecified) and the DataServer is connected client/server (i.e., the -S and/or -H parameters are specific), the client attempts to connect to a DataServer server through the traditional ProBroker brokering environment.
When x=1 and the DataServer is connected client/server (i.e., the -S and/or -H parameters are specific), the client's broker connection is redirected away from the traditional PROBRKR broker environment. Instead the client adopts the protocol used by the Unified Broker framework to make the broker connection. You must ensure that you have started a DataServer broker instance in the OpenEdge Management or OpenEdge Explorer (or via the ubroker.properties files) before attempting to connect a client with the -Dsrv SVUB,1 parameter. There are additional configuration parameters to also consider for connectivity in the Unified Broker framework. See Table 30 for DataServer connection parameters and see Starting and stopping a broker process from OpenEdge Management/OpenEdge Explorer and connecting a client for additional connectivity information.
