Unhandled Exception: ThomsonReuters.RFA.Common.InvalidUsageException for OMMConsumerImpl::registerClient

Hello,

We are using RFA 8.1 api's to get market data from Reuters. We recently started seeing crash which is consistent with same symbol $IDRUSD IDRUSD=R. It's amazing that for others symbols subscribed before this, it works perfectly fine.

@mktdata

I don't think so. They are different processes. Each process has its own process address space.

According to the call stack, the application crashed while sending an item request. You may need to verify the parameters sent to the OMMConsumerImpl::registerClient method.

You may need to catch the exception and print the exception's detail, as shown in the StarterConsumer example.

catch (rfa::common::Exception& e)
    {
        ExceptionHandler::checkException(e);
        ...
        return -1;
    }
 

The ExceptionHandler::checkException method in the ExceptionHandler.cpp in the example code. It will print the status text which may provide useful information.

To investigate this kind of issue, you need to contact the API support team directly via Contact Premium Support, as mentioned by my colleague.

Thanks for reaching out to us.

I can run the StarterConsumer example in the RFA package to subscribe to IDRUSD=R and it can retrieve the data properly.

You may try to update the application to use the latest version of RFA C++ to avoid all known issues.

You can download the API from the Software Downloads and it is in the Category: MDS - API and Product: Robust Foundation API (RFA) - C++. The latest version is 8.2.2.L1.

I hope that this information is of help.

@Jirapongse , We tried with latest library but problem still persist. May I know possible use cases when "OMMConsumerImpl::registerClient" will throw an exception? How to troubleshoot? Could it be due to older dictionary?

@wasin.w @Jirapongse , could it also happen if two applications share same Reuters connection and both subscribe to the same symbol?

When I say they share same connection, what I mean is below configurations are same for both applications -

  • Connections\Connection_RSSL\ConnectionType
  • Connections\Connection_RSSL\hostName
  • Connections\Connection_RSSL\rsslPort
  • \RFAIdentity
  • \DataFeedAppId
