Directory domain with warm standby

Question

Hi. question regarding RTSDK example 470_MP_WarmStandby.

I am subscribing to Directory domain stream to get service statuses.

with ChannelSet failover when after registering to dictionary domain, I can see refresh as expected.

when using WarmStandby mode onRefreshMeg handler in client is not called (Login and dictionary streams on refresh handlers are called after registering)

modified 470_MP_WarmStandby - I registered to domains adding following lines to example

LoginHdl = consumer.registerClient(refinitiv::ema::access::ReqMsg()

                                              .domainType(refinitiv::ema::rdm::MMT_LOGIN)

                                              .initialImage(true)

                                              .interestAfterRefresh(true)

                                              .serviceName("ELEKTRON_DD"),

                                          client);

std::this_thread::sleep_for(std::chrono::seconds(60));

            DirectoryHdl = consumer.registerClient(refinitiv::ema::access::ReqMsg()

                                              .domainType(refinitiv::ema::rdm::MMT_DIRECTORY)

                                              .initialImage(true)

                                              .interestAfterRefresh(true)

                                              .serviceName("ELEKTRON_DD")

                                              .filter(refinitiv::ema::rdm::SERVICE_INFO_FILTER | refinitiv::ema::rdm::SERVICE_STATE_FILTER),

                                          client);

            std::this_thread::sleep_for(std::chrono::seconds(15));

            DictionaryFieldHdl = consumer.registerClient(refinitiv::ema::access::ReqMsg()

                                              .domainType(refinitiv::ema::rdm::MMT_DICTIONARY)

                                              .initialImage(true)

                                              .interestAfterRefresh(true)

                                              .serviceName("ELEKTRON_DD")

                                              .filter(refinitiv::ema::rdm::DICTIONARY_NORMAL)

                                              .name("RWFFld"),

                                          client);

std::this_thread::sleep_for(std::chrono::seconds(15));

            DictionaryEnumdHdl = consumer.registerClient(refinitiv::ema::access::ReqMsg()

                                              .domainType(refinitiv::ema::rdm::MMT_DICTIONARY)

                                              .initialImage(true)

                                              .interestAfterRefresh(true)

                                              .serviceName("ELEKTRON_DD")

                                              .filter(refinitiv::ema::rdm::DICTIONARY_NORMAL)

                                              .name("RWFEnum"),

                                          client);

std::this_thread::sleep_for(std::chrono::seconds(60));

if(DirectoryHdl != 0)

            consumer.unregister(DirectoryHdl);

        if(DictionaryFieldHdl != 0)

            consumer.unregister(DictionaryFieldHdl);

        if(DictionaryEnumdHdl != 0)

            consumer.unregister(DictionaryEnumdHdl);

        if(LoginHdl != 0)

            consumer.unregister(LoginHdl);

Warm Standby feature works as expected, only problem is with DirectoryDomain consumer.

internal directory stream (on consumer creation) gets refreshes from Directory for both active and standby server. Directory refresh at this stage contains the same same set of services, but order of service is not exactly the same.

How can I get Directory messages with warm standby with/without wsb fallback

Hi @Jirapongse

I added delay between domain registration just for test. I don't want to introduce any sleeps in client code. I removed delay, and filters to match your code. still no response.

in trace file I can only see DirectoryCallbackClient logs, I think related to consumer instantiation

I am using RTSDK/2.3.0.L3 but there is nothing in changelog for RTSDK-2.3.1.L1. that would suggest this might be identified or fixed

loggerMsg

    TimeStamp: 12:45:10.882

    ClientName: DirectoryCallbackClient

    Severity: Verbose

    Text:    RDMDirectory stream was open with refresh message Open / Ok / None / ''

loggerMsgEnd

client logs:

I can't see logs related to Directory domain after 12:45:12 (when I issued domain request)

client logs (OmmConsumerClient handlers)

Thank you for reaching out to us.

I would like to clarify the problem.

I am using the following code.

consumer.registerClient(refinitiv::ema::access::ReqMsg()
			.domainType(refinitiv::ema::rdm::MMT_LOGIN)
			.initialImage(true)
			.interestAfterRefresh(true)
			.serviceName("ELEKTRON_DD"),
			client);

sleep(5000);
		printf("
Login Wake Up
");
		consumer.registerClient(ReqMsg().domainType(refinitiv::ema::rdm::MMT_DIRECTORY).initialImage(true).serviceName("ELEKTRON_DD"), client);
		sleep(5000);
		printf("
Directory Wake Up
");
		//while(true)

Without the warm standby, the application could display the directory response correctly.

However, with the warm standby feature, the application didn't receive the directory response.

However, if I remove the sleep between the login and the directory requests, the application can get the directory response properly.

consumer.registerClient(refinitiv::ema::access::ReqMsg()
			.domainType(refinitiv::ema::rdm::MMT_LOGIN)
			.initialImage(true)
			.interestAfterRefresh(true)
			.serviceName("ELEKTRON_DD"),
			client);

//sleep(5000);
		printf("
Login Wake Up
");
		consumer.registerClient(ReqMsg().domainType(refinitiv::ema::rdm::MMT_DIRECTORY).initialImage(true).serviceName("ELEKTRON_DD"), client);
		sleep(5000);

I am using RTSDK-2.3.1.L1.

Please confirm whether this is the issue you’re encountering and specify the RTSDK version you’re using.
