EMA RSSL batch request error - RDMDictionary stream was closed with status message. streamId 4 R...

...eason State: Closed/Suspect/None - text: "Login stream was closed."

Hi ,

I am running EMA java application for streaming real time prices using a batch request. Service discovery is working and it choses below location to connect.
ap-southeast-1-aws-3-sm.optimized-pricing-api.refinitiv.net 14002
But I get error later when consumer runs. I have already read similar posts where similar issues are posted but I am not able to figure out a solution out of the conversations. I am running on a trial license with Refinitiv

The location and names of dictionary files are defined in the EmaConfig.xml.

        <Dictionary>
            <Name value="Dictionary_2"/>
            <DictionaryType value="DictionaryType::FileDictionary"/>
            <RdmFieldDictionaryFileName value="./RDMFieldDictionary"/>
            <EnumTypeDefFileName value="./enumtype.def"/>
        </Dictionary>

You can get them from https://github.com/Refinitiv/Real-Time-SDK/tree/master/Cpp-C/etc.

Regarding the channel dictionary, you can disable log and trace in the EMA.

Can you replicate this issue (ChannelDictionary failed) with ex113_MP_SessionMgmt? If yes, please share the EMA configuration file.

Normally Developer Community Forum is for how-to/general questions but your question seems to be more complex and requires investigation e.g. review source code, configuration, try to reproduce the problem etc. I recommend you raise a query through the Contact Premium Support. You can contact your LSEG account team or sales team directly regarding Contact Premium Support.

Thank you for reaching out to us.

Please run the ex113_MP_SessionMgmt example in the RTSDK Java package to verify what the problem is.

The example uses the Consumer_4 and Channel_4 configuarations. The Channel_4 configuration looks like this.

        <Channel>
            <Name value="Channel_4"/>
            <ChannelType value="ChannelType::RSSL_ENCRYPTED"/>
            <CompressionType value="CompressionType::None"/>
            <GuaranteedOutputBuffers value="5000"/>           
            <Host value="ap-southeast-1-aws-3-sm.optimized-pricing-api.refinitiv.net"/>
            <Port value="14002"/>
            <EnableSessionManagement value="1"/>
            <ObjectName value=""/>
        </Channel>

In the Consumer_4 configuration, please enable Tracing in the API and use the FileDictionary instead of the ChannelDictionary.

        <Consumer>
            <Name value="Consumer_4"/>
            <Channel value="Channel_4"/>
            <Dictionary value="Dictionary_2"/>
            <MaxDispatchCountApiThread value="6500"/>
            <MaxDispatchCountUserThread value="6500"/>
            <XmlTraceToStdout value="1"/>
        </Consumer>

Please share the XML trace when the problem occurred.
