Nack / [500]: Unknown Item: [MYRIC]

I'm trying to publish some items on an internal channel, my code looks like this


UpdateMsg nestedUpdateMsg = EmaFactory.createUpdateMsg()
.streamId(_postStreamID)
.name(ric)
.payload(nestedFieldList);

PostMsg postMsg = EmaFactory.createPostMsg()
.postId(_postID++)
.serviceName(serviceName)
.name(ric)
.solicitAck(true)
.payload(nestedUpdateMsg)
.complete(true);

And in response I get a Nack

Received AckMsg. Item Handle: 1 Closure: com.thomsonreuters.ema.access.OmmConsumerImpl@41545752 ackMesgAckMsg
    streamId="1"
    domain="MarketPrice Domain"
    ackId="1077"
    nackCode="DeniedBySource"
    text="[500]: Unknown Item: TESTABC794481179="
    name="TESTABC94481179="
    nameType="1"
    serviceId="431"
AckMsgEnd

  • Hello @robert.coles

    I sent the same post message as you to the infrastructure which has ATS version 1.4.3.L1:

    <!-- Outgoing Reactor message -->

    The RIC could be created successfully. I got:

    Received AckMsg. Item Handle: 1 Closure: com.thomsonreuters.ema.access.OmmConsumerImpl@7254ddcc
    Item Name: ATS_INSERT_S
    Service Name: not set

    The same post message works on my ATS but does not work on your ATS. Hence, your ATS should be investigated why it sends nacked with "Denied By Source".

    You can reach out to ATS support team who can help you to investigate ATS via Product Support | MyRefinitiv and select Product to be Advanced Transformation System (ATS) .

  • Hello @robert.coles

    Does the item TESTABC794481179= exist in your environment? Are you contributing data to your internal TREP or ATS server?

  • Hello @robert.coles

    The application can receive "[500]: Unknown Item" when the application publishes data of a RIC which does not exist on ATS. Hence, please make sure that TESTABC794481179= is a correct RIC that you would like to publish. If so, you should contact the ATS admin who can create a RIC on ATS. Moreover, you can create the RIC on ATS using EMA application as well. For more details, please refer to the following articles:

    Implementing Elektron API applications to work with ATS - Part 1

    Implementing Elektron API applications to work with ATS - Part 2

  • This is on an internal distribution channel which will have some older SSL subscribers, The RIC does not exist already, The intention is to create the RIC if it does not exist. I'd like to create new RICs dynamically from the applicaiton.

  • It does not exist, my goal is to create it dynamically.If I do use an older RIC that we created via the SFR library it does seem to take the update, but if I use a new RIC I get this error.

  • Hello @robert.coles

    Does your system like below?

    EMA application -> TREP(ADS and ADH) -> ATS

    If so, you can refer to Sample Posting with Adding RIC and Fields section in Implementing Elektron API applications to work with ATS - Part 1 which show how to create a new RIC from EMA application

  • Thanks, so looking at the example, . so if my infrastructure is " EMA application -> TREP -> ATS"

    then if I get this NACK publishing an update, I can assume the RIC needs to be created and then post to name( "ATS_INSERT_S" ) an initial message to "create" the RIC ?

  • Hello @robert.coles

    Yes. That's right.

  • So my createRIC "ATS_INSERT_S" message is nacked with "Denied By Source" too.. The dictionary does have -1 "RIC_NAME" and RSSL is enabled..

    This is my function:


    int pid = Kernel32.INSTANCE.GetCurrentProcessId();

    try(final DatagramSocket socket = new DatagramSocket()){
    socket.connect(InetAddress.getByName("8.8.8.8"), 10002);

    ip = ip + Byte.toUnsignedInt(part);
    }
    } catch (Exception e) {
    logger.warn("problem finding host ip ",e);
    }
    RefreshMsg nestedRefreshMsg = EmaFactory.createRefreshMsg().domainType(DomainTypes.MARKET_PRICE);
    FieldList nestedFieldList = EmaFactory.createFieldList();
    nestedFieldList.add(EmaFactory.createFieldEntry().ascii(-1, ric));
    nestedFieldList = createPayLoad(td,nestedFieldList);
    nestedRefreshMsg.payload(nestedFieldList );

    // .publisherId()

    _ommConsumer.submit(postMsg, _streamHandle);
  • Hello @robert.coles

    Based on your given source code, I sent a Post message below:

    <POST domainType="MARKET_PRICE" streamId="1" containerType="MSG" flags="0x66 (HAS_POST_ID|HAS_MSG_KEY|POST_COMPLETE|ACK)" postId="2" postUserId="24424" postUserAddr="10.46.226.31" dataSize="36">

                    </fieldList>
                </dataBody>
            </REFRESH>
        </dataBody>
    </POST>

    Then, I got an ack message indicating that the RIC was created successfully.

    Received AckMsg. Item Handle: 1 Closure: com.thomsonreuters.ema.access.OmmConsumerImpl@47c063ba
    Item Name: ATS_INSERT_S
    Service Name: not set
    Ack Id: 2
    Text: [4]: Creation Accepted

    Could you share the post message which is sent then you get nacked with "Denied By Source" back?

    You can see the sent/received messages by enabling EMA trace log, set XmlTraceToStdout in EmaConfig.xml to 1. For example:

    <Consumer>
        <Name value="Consumer_1"/>
        <Channel value="Channel_1"/>
        ...
        <XmlTraceToStdout value="1"/>
    </Consumer>
  • Hello @robert.coles

    Please make sure that dictionary does have "X_RIC_NAME" not "RIC_NAME" like below:

    X_RIC_NAME "RIC NAME"   -1  NULL        ALPHANUMERIC       32  RMTES_STRING    32 
  • Confirmed it is in the dictionary as above.
