RFA Dictionary Request returning "Source unavailable" for service hEDD

mktdata

Hi Support Team,
I am experiencing an issue where my RFA (Robust Foundation API) consumer application is unable to retrieve the data dictionary from the hEDD service. Instead of a RefreshMsg, I am receiving a StatusMsg indicating that the source is unavailable.

Issue Details:

• Service Name: hEDD
• Dictionary Names requested: RWFFld and RWFEnum
• Message Model Type: MMT_DICTIONARY
• Response Received:
• Stream State: OpenEnum
  • Data State: SuspectEnum
  • Status Text: "Source unavailable... will recover when source is up"

Code Snippet:

m_reqMsg.setMsgModelType( rfa::rdm::MMT_DICTIONARY );
m_reqMsg.setInteractionType( ReqMsg::InitialImageFlag | ReqMsg::InterestAfterRefreshFlag );
m_attribInfo.setDataMask( rfa::rdm::DICTIONARY_NORMAL );
m_attribInfo.setServiceName( RFA_String("hEDD") );
// Requesting Field Dictionary
m_attribInfo.setName( m_rdmFld ); // RWFFld
m_reqMsg.setAttribInfo( m_attribInfo );
m_rdmFldDictHandle = m_oMMConsumer->registerClient(m_eventQueue, &m_ommItemIntSpec, *this, NULL);
// Requesting Enum Dictionary
m_attribInfo.setName( m_rdmEnum ); // RWFEnum
m_reqMsg.setAttribInfo( m_attribInfo );
m_rdmEnumDictHandle = m_oMMConsumer->registerClient(m_eventQueue, &m_ommItemIntSpec, *this, NULL);

Questions:

1. Does the hEDD service support dictionary downloads (DictionariesProvided) ?
2. If hEDD does support it, are there specific configuration requirements on the ADS/upstream side to enable this for our ID?
3. If the hEDD service entry in the Source Directory explicitly includes RWFFld and RWFEnum in its DictionariesProvided list, why does a subsequent MMT_DICTIONARY request return a "Source unavailable" status?
   
4. Does the presence of these entries in the directory message guarantee that the upstream ADS is currently configured to serve these files, or is there a secondary configuration required on the ADS/upstream side to enable actual downloading for our DACS ID?

Thank you for reaching out to us.

I got the same error when requesting dictionary from the service that is down or unavailable.

I used the Consumer example. From the directory responses, it indicates that the ELEKTRON_DD service is up and the DIRECT_FEED service is down.

Therefore, if the application requests dictionary from the DIRECT_FEED (Down) or DIRECT_FEED1 (not in the service list), the application will get this status message.

Dictionary open/suspect received
Source unavailable... will recover when source is up

Therefore, from the directory response, please make sure that the hEED service is up and available.
