chain subsription

Hello @ranga.gugulothu

To subscribe to a RIC, EMA provides the method registerClient(…) of OmmConsumer class. The method can subscribe the RIC regardless of its domain types e.g. Market Price(i.e. your master RICs and your chain RICs), Market by Price, Market by Order, Market Maker. For more details of each domain type, please refer to [Elektron_SDK_Java_Package]\Java\Ema\Docs\EMAJ_RDMUsageGuide.pdf

The example snipped source code to subscribe to the master RICs TRACEBTDS.FINR and TRACEATDS.FINR to the service named ELEKTRON:

consumer.registerClient(EmaFactory.createReqMsg().serviceName("ELEKTRON").name("TRACEBTDS.FINR"), appClient); 
consumer.registerClient(EmaFactory.createReqMsg().serviceName("ELEKTRON").name("TRACEATDS.FINR"), appClient); 

The default domain type of registerClient(…) is Market Price which is the domain type of your master RICs. Hence, you do not need to specify the domain type in the method. For more details of registerClient(..) method, please refer to [Elektron_SDK_Java_Package]/Java/Ema/Docs/refman/emajava/com/thomsonreuters/ema/access/OmmConsumer.html

I suggest you use example200__MarketPrice__Streaming Consumer application. The application demonstrates how to access Market Price data, decode each field according to its type. Please replace consumer.registerClient(…) in the application with the two lines above. Modify .serviceName(..), .host(…).username(…) to be your service, host and username respectively. The example result when I run the application to subscribe to your master RICs:

Item Name: TRACEBTDS.FINR
Service Name: API_ELEKTRON_EPD_RSSL
Item State: Open / Ok / None / 'All is well'
Fid: 1 Name = PROD_PERM DataType: UInt Value: 5611
Fid: 2 Name = RDNDISPLAY DataType: UInt Value: 152
Fid: 3 Name = DSPLY_NAME DataType: Rmtes Value: CBA
…
Item Name: TRACEATDS.FINR
Service Name: API_ELEKTRON_EPD_RSSL
Item State: Open / Ok / None / 'All is well'
Fid: 1 Name = PROD_PERM DataType: UInt Value: 5928
Fid: 2 Name = RDNDISPLAY DataType: UInt Value: 152
Fid: 3 Name = DSPLY_NAME DataType: Rmtes Value: Freddie Mac

Your chain RICs is Market Price domain so you can use example200__MarketPrice__Streaming to subscribe to them as well.

To understand developing EMA Java Consumer application clearly, I recommend you lean this from EMA Consumer section in Elektron SDK - Java Tutorials

Hello @ranga.gugulothu ,

example200_MarketPrice_Streaming is part of Elektron SDK examples.

One can download the SDK from Downloads tab:

The examples are either consumer or provider, and are partitioned into sections in order of increasing complexity:

100s are the simplest, 200s are more complex, with 400 section containing the most advanced of the SDK examples.

The path to this specific example within SDK is:

Elektron-SDK1.2.0.java.rrg\

Java\Ema\Examples\src\main\java\com\thomsonreuters\ema\examples\training\

consumer\series200\example200__MarketPrice__Streaming

Hello @ranga.gugulothu ,

Please research the fids either RDMFieldDictionary found in in your SDK installation in etc folder or from the front page of this portal use Resources -> Data Model Discovery tool

Hello @ranga.gugulothu ,

Having searched through my copy of RDMFieldDictionary we have no fid named, for example, "PRIOR_DAY_TRADE_CANCEL"

Therefore, is not possible to search up fid number for this field name.

However, the content is likely available and you will need a content expert to guide you, not an API expert.
