We are trying to connect via EMA C++ API to an our assigned Service Name using port 14002
But we receive this error during login process:
Exception subscribing to market data: Exception Type='OmmInvalidUsageException',
Text='Closed / Suspect / User unknown to permissioning system, it could be DACS
, AAA or EED / 'name_of_our_user, unknown to system.''
name_of_our_user is the username used to connect omessed for security.
I solved the problem. The error occurred when there was already a connection established with that user.
Hello @cdefusco,
We appreciate you sharing the solution that you have found.
It really helps the next developers with similar questions.
Hi @cdefusco, are you using one of the EMA example programs.
You will need a valid DACS user name which is permissioned to get data for instrument of interest.
In the OMMConsumer example:
OmmConsumer consumer( OmmConsumerConfig().host( "ADS:14002" ).username( "user1" ) );
the username has to be a valid DACS user name. To get a valid DACS username, please contact your market data team which manages your ADS/TREP infrastructure.
Is strange because when we use the SpeedGuide_2.1 with the same information (host,port,servicename and username) it works fine and we receive data for example using as RIC "EUR=".
Could be a problem of configuration in DACS station associated to permissions?
EUR= is not a fee liable data. Are you requesting same RIC in the consumer example as well?
Can you configure EMA logging and attach the log file here. See configuration article on how to enable it.
Additionally you can ask the administrator to check the ADS logs.
