270__SymbolList can not get the data

I run the Example: Cpp-C/Ema/Examples/Training/Consumer/200_Series/270__SymbolList

Consumer.cpp:

try {
AppClient client;

OmmConsumer consumer( OmmConsumerConfig().host( "localhost:14002" ).username( "user1" ) );

UInt64 handle = consumer.registerClient( ReqMsg().domainType( MMT_SYMBOL_LIST ).serviceName( "ELEKTRON_DD" ).name( "0#/MBD.HK" ), client );

}
but I get the result :

Item Name: 0#/MBD.HK
Service Name: ELEKTRON_DD

Item State: Closed / Suspect / Not found / 'The record could not be found'

how can i the the result success,
what the Consumer.cpp should be.?

Hi @luxiangyuan

The message means that the RIC you have requested is not available in a SymbolList Domain format.

The RIC is actually the older Chain format - so you would request using the default MarketPrice domain.

Please see the following two articles for an example of Chain handling using EMA

Simple Chain objects for EMA - Part 1

Simple Chain objects for EMA - Part 2

Hi @luxiangyuan

The techniques and mechanism described in the article for processing Chains is much the same in C++ and Java. So, you could refer to the articles and use the understanding to develop your own code to process chains in C++.

EMA does not provide any built in classes for processing Chains specifically.
