WARNING: XSW com.reuters.rfa.omm.OMMException

We encountered this exception from RFA library, and no more dispatchToClient be called after that. What could be the cause to this?

Hi @karshiang

Looking at the stack trace and the error message, this could be because you are using old Data dictionary files. New FIDs or new enumerated values could have been added to the dictionary files being used by the feed you are consuming from - but if those items are not present in the data dictionary files you are using then the API cannot parse those fields.

If you are loading RDMFieldDictionary and enumtype.def locally then these could be out of date. If you are downloading from the ADS server, then it could be that your Market Data team has not updated the files on the TREP servers.

TREP Template Service Pack 4.19.6 is the latest Data Dictionary package. You can download the latest data Dictionary files as described in this post.

If you check your data dictionaries and they are up to date - then the exception would require further offline investigation. Please raise a Premium Support ticket (if the link does not work please speak to your Refinitiv Account manager or your Market Data team to confirm if you have RDC membership).

Hi @karshiang

TREP Template Service Pack 4.19.6 is the latest Data Dictionary package. You can download the latest data Dictionary files as described in this post.

Hello @karshiang

What
is the version of the RFA Java API that encounters the problem? If the
version is below 8.1.0 and you can replicate issue in non-production
environment, I suggest you test the issue with version 8.1.0 E2 which is
the latest version.

If you still encounter the problem with the latest version of API and Data dictionary, please

Please raise a Premium Support ticket as my colleague suggest above.

we were using RFA 8.1, and tries the RFA 7.6.1.E2 (2019). both are giving various exception from library. We will check if dictionary is out dated. Our code will download from server automatically daily, will check with market data team as well!

Thanks for your advice, I am also suspecting if dictionary is outdated from the server we downloaded from. We will check with the data team.
