error: trying to consult a RIC from the TREP server the data dictionaries exist on the server with reading permissions, it only works if downloadDataDict is changed from TRUE to FALSE and creating in a local way the dictionaries, in addition, you can add to the connection the routes/paths that were previously created
Attempt to download MarketFeed dictionary failed
You have mentioned that you can consume RICs using OMMViewer - which uses an RSSL connection on port 14002. Therefore, please test with another 8101 (SSL) example such as the MDSubDemo mentioned above by my colleague.
You stated that the problem has arisen after a recent TREP upgrade - so it is possible that whilst the RSSL related config is correct, there may be an issue with the SSL related config.
This problem arose recently after a reinstallation that was carried out in the TREP.
We query the rics through a MATLAB function, our connection is like the following:
The only way we can consult it is as I mentioned above if downloadDataDict is changed from TRUE to FALSE and creating the dictionaries locally.
In addition we can also consult rics through the OMM Viewer.
A little disclaimer. I am not familiar with MatLab adapter, only RFA. In addition to the suggestion from @wasin.waeosri, would it make sense to verify, that the newer dictionaries that are now being made available from local Refinitiv Realtime Distribution System (TREP) are compatible with MatLab adapter code? The local dictionaries you have continue to work, but likely are older. It may be worth finding out with MatLab what dictionary versions are supported and next inquiring with local market data group, what version of the dictionaries is downloadable, to see if this is the issue. Perhaps there is an adapter upgrade that is required. The version of the local appendix_a dictionary, just in case, can be found at the top of the dictionary file.
MDSubDemo is a code example, that was part of MD-enabled versions of RFA 7.x (8.X version do not support MD, only OMM). My understanding is that you are in Java, see Downloads-> rfaj7.7.0.L1.zip, you may need to request access to download it, should not be available for download automatically, as this is an old version and we discourage new development with it, should be done with Refinitiv Realtime SDK APIs.
Alternatively, it may be easier to test with pre-build operations test tool rmdstestclient that is part of Infra Tools package , operations package of test tools, that can be downloaded by clients ( use client account) via My Refinitiv -> Products -> Software Downloads -> MDS Infra -> Infrastructure Tools.
Hope this helps
