I have an EMA C++ consumer appilcation which does offstream posting. I want to run multiple instances using the same machine account/password. Is this allowed?

I have an working consumer application with offstream posting based on :

https://developers.refinitiv.com/elektron/elektron-sdk-cc/learning?content=26452&type=learning_material_item

I would like to run multiple instances. Each instance posts (contributes) a different set of data.

Sometimes when I start up the 2nd instance, it closes the connection on the first instance and sometimes, it doesn't.

I am using the same machine account/password and the same EmaConfig.xml for both instances.

I'm not sure what I need to change, to make this work properly.

Thanks

Hello @efreeman,

Some fixes around mutli-consumer via the same machine id were introduced in ESDK version 1.4. Are you perhaps on 1.3 version? If no, please disregard. If so, please consider testing with the latest version that has all the latest fixes, 1.5.

Hi @efreeman,

I have received the response form Contributions product team. An application is not allowed to use same credentials more than once, concurrently. Hope that clarifies.

Hello @efreeman,

I don't think multiple instances are allowed to connect, using the same set of credentials. Your second instance might be getting past this by being routed to a different server by the load balancer - but it is not always guaranteed to work.

I will check with product team about the correct protocol for multiple applications.

Hi Gupreet,

I was waiting for your followup. It seems like I will probably need multiple credentials in order to have multiple connections.

Thanks.
