Elektron SDK C++ tutorial example - Unable to login

I am currently trying the tutorial example for contributing data "Elektron Message API - Consumer Tutorial - Posting data to TR Contribution Channel" on a Windows 10 machine.

The following line seems to timeout:

OmmConsumer consumer(OmmConsumerConfig().host("ecc01-emea1.fr.aws.thomsonreuters.com:443").username("GE-A-01281282-3-2411"));


And I get the following error:

Exception Type='OmmInvalidUsageException', Text='login failed (timed out after waiting 45000 milliseconds) for ecc01-emea1.fr.aws.thomsonreuters.com:443)', ErrorCode='-4052'


I believe the server and port are correct and the username is the one I received.

Any ideas?

Thanks

For Windows, EMA needs to have an encrypted protocol type set to SOCKET. Please see the Channel_3 configuration in EmaConfig.xml provided in Cpp-C/Ema/Examples.

The line is:

<EncryptedProtocolType value="EncryptedProtocolType::RSSL_SOCKET"/>

This encryption type requires OpenSSL libraries, which are not built by the Elektron SDK package. Please see chapter 4.3.3: Encrypted Connections in the EMA Developer's Guide for more information.

Hi @mitchell.katoTR

Is this a new thing? The current tutorial does not reflect this setting:

This functionality was added in 3.3.0, which was released in March 2019.

Thank you for pointing this out. It is working now.

Hi @emir.subasic

The above host value is a valid TRCC mount point and should be working fine.

Just want to check you are following all the steps in the tutorial - including changing the Channel Type to RSSL_ENCRYPTED from the default RSSL_SOCKET

Rather than hard coding the host:port into the source code, change the config file as described in the tutorial for now and confirm it all works.

Hi,

Below is a screenshot that illustrates the usage and the error I am getting. As you can see the xml is updated for Channel 1 and 2. It is in the same directory as the source. When run it is somehow still picking up localhost.

I guess that's the default when not specified:

OmmConsumerConfig& host( const EmaString& host = "localhost:14002" );


See error below.

Any ideas on whats wrong? Thanks

Hi @emir.subasic

The EmaConfig.xml files needs to be in the Working Directory which defaults to the location where the Project files etc are located i.e. $(ProjectDir)

For example, on my PC I placed the EmaConfig.xml file in

C:\Code\ESDKC131VS2017\Cpp-C\Ema\Examples\Training\Consumer\300_Series\341__MarketPrice__OffStreamPost

where C:\Code\ESDKC131VS2017 is the location of my main esdk.sln file.

If you copy the file to that location, it should pick up the contents of the file.
