qiang.zhu

I compiled "RFA .NET Tutorials\step8\MRNExample_VS120.sln", with visual studio 2013

updated below stuff

*** file "ExampleRFA.cfg"

\Connections\Connection_RSSL\rsslPort = "MY_PORT"

\Connections\Connection_RSSL\hostName= "MY_HOST"

*** source code : "RFA .NET Tutorials\step8\RDMExample.cs"

private static readonly RFA_String UserName = new RFA_String("MY_ACCOUNT");

private static readonly RFA_String ServiceName = new RFA_String("MY_SERVICE");

private static readonly RFA_String ItemName = new RFA_String("EUR=");

can connect to the server, but failed to login (Login Denied, NotAuthorized).

Basically the status text was generated by Infra because the Login request does not contains valid DACS Position. I guess that you are connecting to ADS or TREP component which turn on DACS Entitlement so it require a valid DACS position from OMM Login request message.

The example leave the Position to blank so you need to modify it to a valid DACS Position like "<You Client IP>/net", "10.42.20.33/net"

You have to modify the follwoing line from RDMExmaple.cs in class RDMExample

private static readonly RFA_String Position = new RFA_String("");


to the new position like the following sample


private static readonly RFA_String Position = new RFA_String("127.0.0.1/net");

Don't forget to change UserName and ServiceName property to valid one as well.

Hope this help.

Hi @qiang.zhu,

Are you using a valid user name? The error message says clearly the user you used to login is not authorized. Have you checked with your MarketData group or whoever provided the connection host information to you?

I confirmed with the team. ther user name is good.

We can confirm that your username is authorized
access in DACS as shown in screenshot below, also attached.

We have also verified that your username can get
data for EUR= on the MY_HOST server.

regarding to error msg :

A21: A required argument was NULL

is it possible to find more info??

I can enrich add source code on necessary

thanks

I can connect to server successfully. modify below line
private static readonly RFA_String ItemName = new RFA_String("EUR=");

try to get data for "EUR=".

but the log shows:

2017/07/11 12:17:01.501 INFO : <- Received MMT_MARKET_PRICE Status EUR=

serviceName : EED_DELAYED

symbolName : EUR=

streamState : Closed

dataState : Suspect

statusCode : NotFound
statusText : The record could not be found

confirmed with server side, "username/positions/etc" are all good to get data for "EUR="

could you advise??

thanks
