EMA Java - Request timeout

When we receive a StatusMsg like the following

StatusMsg    streamId="5"    domain="MarketPrice Domain"    state="Open / Suspect / None / 'Request timeout'"    name="TICKER"    serviceId="10"    serviceName="ELEKTRON_DD"StatusMsgEnd

Is it possible to close this stream with the given streamId when this occurs. This is to prevent EMA from sending repeated timeout status messages.

Thank you for reaching out to us.

Yes, you can unregister an item calling the unregisterClient method with a handle (UInt64) returned by the registerClient method.

However, if you use a batch request, you can get an item's handle from the AppClient::onStatusMsg callback method by calling the OmmConsumerEvent::getHandle() method inside the callback.

Otherwise, you can change the RequestTimeout value in the consumer configuration. The default value is 15 seconds.

Thank your for your earlier guidance, I've implemented the suggested changes using event.handle() method. However, after adjusting the request timeout value to 100 milliseconds, I've encountered a new issue.

I got the following message when creating the ommConsumer

c.refinitiv.ema.access.OmmConsumerImpl : loggerMsg

ClientName: ChannelDictionary

Severity: Warning

Text: RDMDictionary stream state was changed to suspect with status message

streamId 3

Reason State: Open/Suspect/None - text: "Request timeout"

loggerMsgEnd

This prevents me from even sending a request to the server, thereBy making it challenging to test the original "Request timeout" issue.

100 miliseconds is too small. You can use the default value (15000) or increase the value.
