Getting out of buffer exception due to slow consumer (EMA C++ OMM API)
I'm building a interactive provider (EMA C++ OMM API) for streaming the market data to different downstream applications, which are Refinitiv Consumer, through TCP socket. I'm testing the scenario that how my provider behaves when I have very slow consumer connect to it. I found that the provider will throw an out of…

Several times during the market hours the application logs misses updates due to buffer overflow (logged internally by the application). Are the below [numOutputBuffers] setting enough for high volume data updates? What other parameters can be tuned…

Java TREP UPA API - Choosing an Optimal Buffer SIze
Hi, my application is using the Java UPA API and requesting data from RWF. I have a large subscription list (~400k) and request data in batches of 2048. I have noticed that with such a large list of subscription, the subscription requests drop some symbols in random every time and end up subscribing to a lesser number of…

OMM Provider settings to avoid RSSL buffer failures
We have a high throughput provider application that from time to time disconnects after an OMM Error "Attempt to get rssl buffer failed" is triggered. From what we understand, this can occur when there are issues sending data between the provider and the ADH (network blip, capacity issues, ...). We increased…

Buffer owerflow when Running RFA7 and contributing RICS (SSL)
When contributing RIC:s to the feed I'm running into buffer owerflow. I do not know how to adjust this - is it possible and is if any configuration parameter for my RFA libraries (rfa_registry.xml or property config) or any settings in the AHD/AHS required to chance to increase the buffers. The problem is intermittent and…

JRFA objects not garbage collected?
When running a server side app with 1000+ subscriptions, profiling from VisualVM shows that number of instances of some internal objects for eg com.reuters.rfa.internal.rwf.RwfTypedBuffer keep increasing (into millions) and don't get garbage collected for some reason. We're trying out a few scenarios with larger Java heap…

Adjust Buffer size when encoding a message
Hello When encoding a message using the rssl functions, often the size of the resulting message is unknown so at the start a big buffer needs to be created (sometimes way larger than the resulting message size). Is there a clean way of creating a buffer and then making it bigger if it is not large enough? Thanks
