Frequently Asked Questions

What is the recommended udpSocketBufferSize?

A: It can depend on the environment; our test shows that 8Mb is enough. So the best way is to do a few tests with different values and then choose.

Is there any notification given to the application when an incremental packet gap is detected by OnixS?

A: When the gap is detected, OnixS::B3::MarketData::UMDF::MessageListener::onIncrementalChannelGap will be fired to notify that market data is not valid.

Can more than one channel per Handler be processed? Alternatively, are multiple Handler instances necessary?

A: One instance of the Handler processes market data for a single channel only. Users must create multiple instances of the Handler to process data from multiple channels.
