Hi Team,


I am trying to run example Consumer 100 and facing the below error. How to resolve this?


Code:
AppClient appClient = new AppClient();
OmmConsumerConfig config = EmaFactory.createOmmConsumerConfig();
consumer  = EmaFactory.createOmmConsumer(config.host("10.186.204.18:14002").username("test123"));
ReqMsg reqMsg = EmaFactory.createReqMsg();
consumer.registerClient(reqMsg.serviceName("DIRECT_FEED").name("IBM.N"), appClient);
Thread.sleep(60000);// API calls onRefreshMsg(), onUpdateMsg() and onStatusMsg()
ERROR:
16:24:29.584 [main] WARN com.refinitiv.ema.access.OmmConsumerImpl - loggerMsg
    ClientName: ChannelCallbackClient

    Ok, this is back to the basics question - do you have a local market data infrastructure - ADS? If yes, please contact your administrator for hostname and username details.

    If not, are you a Refinitiv Real Time Optimzed customer - i.e. connecting to a cloud setup? In this case, Refinitiv would have provided you with a machine name, password and you would have setup a client ID. For details on how to use RTO - I recommend that you start with this step by step Quickstart guide.

    Hello @Maha Rana Parthap Sing,

    Can you please post the complete log and error message. It seems like your application was able to connect successfully, but unable to login to the server. Is the username a valid DACS configured user?

    You can enable the raw logs from the API, but setting this configuration parameter in the configuration XML file:

    <XmlTraceToStdout value="1"/>

    Hi @Gurpreet,


    [Guru]: Is the username a valid DACS configured user.

    [Rana]: I have taken the sample and started running. I am not sure from where I get these actual values (host, username).

    I have added the following statement in EmaConfig.xml "<XmlTraceToStdout value="1"/>". Still, I don't see the raw data logs. 

    <Consumer>
    <!-- Name is mandatory-->
    <Name value="Consumer_1"/>
    <!-- Channel is optional: defaulted to "RSSL_SOCKET + localhost + 14002" -->
    <!-- Channel or ChannelSet may be specified -->
    <Channel value="Channel_1"/>
    <!-- Dictionary is optional: defaulted to "ChannelDictionary" -->
    <Dictionary value="Dictionary_1"/>
    <XmlTraceToStdout value="1"/>
    </Consumer>

    Hello @Maha Rana Parthap Sing

    Did you place the EmaConfig.xml file in the application working directory? The API looks for the file in the working directory by default.

    Alternatively, you can change the file location too. Please check EMA Java example ex111_MP_UserSpecifiedFileCfg for more detail
