Exception subscribing to market data: Exception Type='OmmInvalidUsageException',

I solved the problem. The error occurred when there was already a connection established with that user.

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?
