    The consumer can get StreamState::NON_STREAMING when using snapshot request. In EMA, the consumer can set interestAfterRefresh(false) to send snapshot request.

    consumer.registerClient( ReqMsg().serviceName( "ELEKTRON" ).name( "IBM.N" ).interestAfterRefresh(false), client );

    After that, the stream state of the response will be Non-streaming.

    Item Name: IBN.N
    Service Name: ELEKTRON
    Item State: Non-streaming / Ok / None / 'All is well'
    Fid: 1 Name: PROD_PERM value: 213
    Fid: 2 Name: RDNDISPLAY value: 153
    Fid: 3 Name: DSPLY_NAME value: BARCLAYS     LON
    Fid: 5 Name: TIMACT value: 08:20:00:000:000:000

    From the response, you got the XML tracing. Please provide the full XML tracing. We can know the available service names from the XML tracing.

    You can enable XML tracing by using <XmlTraceToStdout> or <XmlTraceToFile> under the channel (Channel_1) of the default Consumer (Consumer_1). The EMA configuration file is EmaConfig.xml.

    <Channel>
    	<Name value="Channel_1"/>		
    	<ChannelType value="ChannelType::RSSL_SOCKET"/>
    	<CompressionType value="CompressionType::None"/>
    	<GuaranteedOutputBuffers value="5000"/>
    	<ConnectionPingTimeout value="30000"/>	
    	<TcpNodelay value="1"/>
    	<Host value="localhost"/>
    	<Port value="14002"/>
            <XmlTraceToStdout value="1"/>
    	<XmlTraceToFile value="1"/>
    </Channel>

    The available services are in the refresh message of RSSL_DMT_SOURCE domain.

    <refreshMsg domainType="RSSL_DMT_SOURCE" streamId="2" containerType="RSSL_DT_MAP" flags="0x168 (RSSL_RFMF_HAS_MSG_KEY|RSSL_RFMF_SOLICITED|RSSL_RFMF_REFRESH_COMPLETE|RSSL_RFMF_CLEAR_CACHE)" groupId="0" dataState="RSSL_DATA_OK" streamState="RSSL_STREAM_OPEN" code="RSSL_SC_NONE" text=""  dataSize="3206">

    Each mapEntry will contain the service information. You can find the service name from the "Name" elementEntry.

    <mapEntry flags="0x0" action="RSSL_MPEA_ADD_ENTRY" key="2115" >

    <filterList containerType="RSSL_DT_ELEMENT_LIST" countHint="0" flags="0x0"> <filterEntry id="1" action="RSSL_FTEA_SET_ENTRY" flags="0x0" containerType="RSSL_DT_ELEMENT_LIST">

    <elementList flags="0x8 (RSSL_ELF_HAS_STANDARD_DATA)">

    <elementEntry name="Name" dataType="RSSL_DT_ASCII_STRING" data="API_ELEKTRON_EPD_RSSL"/>
