trna via elektron on DACS

i have a client in Abu dhabi (ADIA) who have subscribed to TRNA via Elektron SAAs and also have DACS at their premises. The client is a little lost on how he can start using the data after the DACS id has been created by the client admin. Can someone please help?

Hello @Rishabh.Maheshwary

What is the API that the client currently using?

OMM

The Open Message Model (OMM) is a collection of message header and data constructs that running in Elektron/TREP infrastructure. If the client connects to Elektron via RSSL connection, the client is already using OMM interface.

Application ID and Position

Application ID: The DACS application ID. If the server authenticates with DACS, the consumer application might need to pass in a valid ApplicationId. This must be unique for each application. IDs from 1 to 256 are reserved for permanent market data applications. These are assigned by Refinitiv and will be uniform across all client systems. IDs from 257 to 65535 are available for site-specific use.

  • Datatype: ASCII
  • Range: 1-65535
  • Example Value: 256

Position: DACS position. If the server is authenticating with DACS, the consumer application might need to pass in a valid position which is an IP Address of the consumer machine in "IP Address/Hostname" or "IP Address/net" string format.

  • Datatype: ASCII
  • Format: IP Address/hostname or IP Address/net
  • Example: 192.168.1.1/net

Hello @Rishabh.Maheshwary

Please note that once you have setup DACS permission on your site, you need pass three parameters with the OMM Login request message to login.

  • Application ID
  • Position
  • Username (DACS ID)

You can find more detail in this [EMA C++] State: Closed / Suspect / Not entitled / 'A21: A required argument was NULL question (It can be applied to any Elektron SDK APIs).

@Wasin Waeosri could you please describe what OMM is? Also, could you tell me what the Application ID and Position would mean. Sorry if i sound super naive on this.
