C++ NIProvider publishing to ADH service does not work

Deary · 2025-05-07T02:00:11+00:00

There was an error rendering this rich post.

I am testing according to lseg C++ NIProvider tutorial.I am testing on internal service “DTS_KL” of internal ric “USDFON=MBBGM”, the codes are like the following.OmmProvider.

provider(OmmNiProviderConfig("c:\\temp\\process\\x64\\EMAConfig.xml").username("drdwhw"));

UInt64 serviceId = 1000;

UInt64 sourceDirectoryHandle = 1;

UInt64 ibmHandle = 5;

RefreshMsg refresh;

UpdateMsg update;

FieldList fieldList;


Connector::ConnectionStateListener _connectionStateListener;


provider.registerClient(ReqMsg().domainType(MMT_LOGIN).name("drdwhw"),_connectionStateListener,(void*)0);


provider.submit(refresh.clear().domainType(MMT_MARKET_PRICE).serviceName("DTS_KL")

	.name("USDFON=MBBGM").state(OmmState::OpenEnum,OmmState::OkEnum,OmmState::NoneEnum,"UnSolicited Refresh Completed")

	.payload(fieldList

		.addReal(22, 4.21, OmmReal::ExponentNeg2Enum) //BID_1 - 23, BID - 22

		.addReal(25, 4.22, OmmReal::ExponentNeg2Enum) //ASK_1 - 26, ASK - 25

	.complete()).complete(), ibmHandle);


provider.submit(update.clear().domainType(MMT_MARKET_PRICE).serviceName("DTS_KL")

	.name("USDFON=MBBGM").payload(fieldList.clear()

	.addReal(22, 4.21, OmmReal::ExponentNeg2Enum) //BID_1 - 23, BID - 22

	.addReal(25, 4.22, OmmReal::ExponentNeg2Enum) //ASK_1 - 26, ASK - 25

	.complete()), ibmHandle);


provider.submit(StatusMsg().state(OmmState::OpenEnum, // Stream state

	OmmState::OkEnum, // Data state

	OmmState::NoneEnum, // Data status

	"All is good"), // Explanatory 

	textibmHandle);

Our IT has checked that the ADH service is running, and I can get call back saying that refresh is completed after I send refresh message. This shows that I can connect to ADH service. Now my problem is after I submit the update message the data is not updated.

support ticket raised as 14606472 as well.

Hello @Deary

I see that an application code has published a refresh message, an update message (single update), and a status message to ADH continuously without a pause between the messages. The values of BID and ASK fields of the Refresh and Update messages are also the same value (4.21 and 4.22) which make it harder to detect a change.

Could you please try the following tasks?

add some pause (sleep) between the message submit
add a loop to submit multiple update messages with various values updated

Then you can track on a consumer's update callback easier

Example:

provider.submit( RefreshMsg().serviceName( "DTS_KL" ).name( "USDFON=MBBGM" )

	...

	.complete(), itemHandle );


sleep( 1000 );


for ( Int32 i = 0; i < 60; i++ )

{

	provider.submit( UpdateMsg().serviceName( "DTS_KL" ).name( "USDFON=MBBGM" )

		.payload( FieldList()

			.addReal( 22,  5.5 + i, OmmReal::ExponentNeg2Enum )

			.addReal( 25, 10.9 + i, OOmmReal::ExponentNeg2Enum )

			.complete() ), itemHandle );

	sleep( 1000 );

}

You can see the full example on GitHub EMA C++ 100_MP_Streaming example.

Additionally, you can post a code by clicking on the menu on the left and choose "" —> </> Code Block option.

I did the code change and it does not work.

the quote in workspace does not change at all.

however if i use excel to publish, it works, now the values in workspace shows 4.31 and 4.32 for bid and ask respectively.

i only receive on refresh message callback of the following, OmmProvider registerClient does not allow me to listen to updatemsg and statusmsg callback, can you tell me how to check update status?

As far as I know, Excel uses posting or contribution to post data to a service. It uses a different mechanism from NIProvider.

What is the DTS_KL service? Is it the service from ATS or DTS server?

Typically, the cacheLocation and cacheType of a NI service must be ssl and sourceDriven respectively.

…*DIST_PUB*cacheLocation : ssl
…*DIST_PUB*cacheType : sourceDriven

Moreover, why does the ConsumerClient have the niProvider? It seems that it retrieves data and then republishes the data to another NI service. Please confirm the consumer's behavior.

Moreover, please share the ADH configuration file and the application diagram.

Deary

DTS_KL is DTS server

ConsumerClient is responsible to receive message update from niProvider, I am using to see if i get any error from refresh or update message.

I am getting IT to retrieve ADH configuration file and application diagram.

in the meantime, can you tell me where to set cacheLocation and cacheType?

Jirapongse

@Deary

DTS server is an interactive provider. You can't use NIProvider to publish data the to DTS server.

To contribute data to DTS, you need to use Posting. Please refer to the following articles:

Deary

By interactiveProvider do you mean refinitive workspace has to be loggon and the service must run at user's machiine?

in the codes, it does not set any remote service ip address, only a port.

in sample emaconfig i also do not see any ip address supplied.

		AppClient appClient;
		OmmProvider provider( OmmIProviderConfig().port( "14002" ), appClient );

@Deary

If you would like to post updates to items on the DTS service (DTS_KL), you need to use posting. Please see the example here.

Moreover, please refer to the following articles:

If not, could you please explain what you would like to do?

Deary

Thank you for your help, yes i need to post update to DTS service.

I managed to publish something to DTS on this RIC USDFON=MBBGM

However I have two questions:

the example shows publishing done inside onrefreshmsg after login, i move the post msg outside after getting the event handle.

is this recommended? is the event handle valid throughout the consumer lifecycle?

2. can you advise how to publish a value like 4.21 into BID filed? if i use Exponent0Enum, i can see only integer value 4 published.

Hello @Deary

I can help with the 2nd question. You can use the ExponentNeg2Enum to send OmmReal with power of -2.

Example Code:

.addReal(22, 421, OmmReal::ExponentNeg2Enum )

There is a document on <RTSDK C/C++ package>/Cpp-C/Ema/Docs/refman/ about each real number magnitude types:

Jirapongse

For the first question, it is fine. The login handle will remain valid as long as the application is still connected to the server.
