Hi all,
please help me with this issue.
Context: EMA C++ based application, using an OmmProviderClient that downloads the Data dictionary over the Login connection.
Issue: timeout while downloading the dictionary (RWFFld is downloaded, RWFEnum isn't).
In the context of reqMsg for login request, the application starts the dictionary download as follows:
..registerClient(ReqMsg().name("RWFFld").filter(DICTIONARY_NORMAL).domainType(MMT_DICTIONARY), ..); ..registerClient(ReqMsg().name("RWFEnum").filter(DICTIONARY_NORMAL).domainType(MMT_DICTIONARY), ..);
From the EmaTrace logs, I can see that the application downloads all the 17255 entries expected in RWFFld within a single refresh message, but no messages at all are received for the request on RWFEnum.
After 15 seconds, the application is notified of the following event (I'd say by the EMA engine itself, due to RequestTimeout hit?):
StatusMsg streamId="-2" domain="Dictionary Domain" state="Closed, Recoverable / Suspect / None / 'request is timeout'" name="RWFEnum" filter="7" StatusMsgEnd
What could be the reason for this issue? A problem in the code, or something else?
Thanks
Best Regards,
Paolo
