...(timed out after waiting 45000 milliseconds)

Do you know how to configure my RFA to use local field dictionary file instead of downloading that from upstream system or TREP ?

We are receiving below error when try to connect one of publisher server.

Hello @ryusuke.kamimura

I must admit that I am not the C++ API Guy. However, based on my research the RFA C++ rfa::rdm::RDMFieldDictionary class also has the same kind of methods as follows:

readRDMEnumTypeDef()
readRDMFieldDictionary()

Hope this helps.

Hello @ryusuke.kamimura

The error message indicates that the API cannot get the Real-Time dictionary information (either RDMFieldDictionary or enumtype.def) from the OMM Provider on time.

About loading local data dictionary files, you can use RFA Java FieldDictionary.readRDMFieldDictionary() and FieldDictionary.readEnumTypeDef() methods as follows:

Please see more detail on the following RFA Java example in the API package

- StarterConsumer.java

- com.reuters.rfa.example.utility.GenericOmmParser.java

Hi @ryusuke.kamimura

Additionally, you can use the RFA Java parameter "dictionaryRequestTimeout" to adjust the time (in milliseconds) to wait for a provider to send back dictionary responses before timing out the dictionary request and sending a dictionary close request back to the application.
