lseg C++ NIProvider query

Raisd on behalf of client

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 text


ibmHandle);

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.

Thank you for reaching out to us.

Typically, raising questions on behalf of client is not recommend. You can suggest the clients to post questions by themselves. The forum is public so anyone can access it.

Regarding this issue, you can change the values of BID and ASK in the update messages. For example:

provider.submit(update.clear().domainType(MMT_MARKET_PRICE).serviceName("DTS_KL").name("USDFON=MBBGM")


.payload(fieldList.clear()


.addReal(22, 5.21, OmmReal::ExponentNeg2Enum) //BID_1 - 23, BID - 22


.addReal(25, 5.22, OmmReal::ExponentNeg2Enum) //ASK_1 - 26, ASK - 25


.complete()), ibmHandle);

I changed the values of BID and ASK to 5.21, and 5.22 respectively.

Therefore, we will know that the values retrieved by the consumer is from the refresh message or update message.
