Heartbeats configuration in Apache.NMS.Stomp Version 1.5.4.3215

[richie...@gmail.com]

Hi folks. I'm using c#.net to create a connection to the RTPPM feed. Each night, my consumer service stops receiving messages (12:00 or 02:00) always on the hour. At this point, the consumer service stops receiving messages and doesn't "wake up" when a new one arrives, so I have to restart the consumer service. I've seen that it's a good idea to implement heartbeats and durable connections, however I'm finding the documentation for NMSConnectionFactory confusing. Has anyone out there implemented heartbeats / durable connection using a NMSConnectionFactory?

My code (extract) at present is this ...

IConnectionFactory factory = new NMSConnectionFactory(new Uri(_mySettings.DataFeed));

...where _mySettings.DataFeed = "stomp:tcp://datafeeds.networkrail.co.uk:61618"

Thanks in advance for any guidance you can provide :-)
Cheers, Richie, York.

once youve got an ISession there is a CreateDurableConsumer method.

There is some code in here, although it might be a bit confusing:

https://github.com/blueghostuk/trainnotifier-server/blob/master/NetworkRailDownloader.Downloader/NMSConnector.cs

see the CreateConsumer method. The ActiveMQDurableSubscriberId" setting is just a unique string i made up that I think registers itself as the durable subscription id, so if you lose connection and reconnect with the same id it will resend the missed messages.

Heartbeats Im not sure about, but I run my application as a service that restarts on failure (e.g. due to connection drop out) so I'm not too bothered about that.

I don't think they are supported, judging by the available configuration options:
http://activemq.apache.org/nms/stomp-uri-configuration.html

However if anyone knows otherwise please correct me.

(21 months later)
I can't find any documentation on the heartbeats either (still), just a "die after n milliseconds of inactivity" setting which is not helpful. I'm not really keen on dropping and restarting the connection just because of inactivity - seems a bandaid fix rather than preventing it in the first place.

Specific exception is:
Apache.NMS.Stomp.IOException: Channel was inactive for too long: tcp://datafeeds.networkrail.co.uk:61618/

So, 21 months later, is there still no solution or do I have to write my own client to handle the heartbeats properly? Or is there another STOMP client I can use for .NET?

Thanks.
