Subscriber message processing failure and retry

What I wish to do is two-fold:

 

1) Capture the error on processing from a subscriber.  I can do this by turning on auditing (which I have tested, works fine).

 

2) Submit the message for re-processing after I have corrected my code/data.  This I do not see a built-in way to do, but I'm hoping that I just don't understand how to properly fail.

 

What I have done is setup a simple test in a subscriber.OnReceive that displays the message and then uses the line below to notify the bus of a failure:

 

m_subscriber.FailMessage(Neuron.Esb.Internal.ESBHelper.Direction.Receive, e.Message, new Exception("Handling Failed!"));

 

This does cause the auditing report to pick up the entry, and I did see it in my database so I suppose I can roll my own re-sender, but if the message viewer dialog had a resend button (and perhaps a delete) I wouldn't have to do anything.  Unless of course there's a better way.

 

Thanks

Ken

Hi Ken,

You would have to roll your own resubmit logic. You'll need to deserialize the message into an ESBMessage.

Thank you, now I can quit looking.

I do wish you would add that feature in a future version. You're most of the way there. Additionally, please add the option to delete an individual failure item. Currently we can only do a purge on all.

Yea, deserialize the byte array from the message column into an ESBMessage. Er, how? The obvious (to me) don't seem to work. XmlESBMessage.ConvertBytesToMessage seems like the appropriate routine, but it throws.

Never mind. Message needs to be deflated first. Reflector is a nice tool, never knew it could disassemble.

Msmq network transport error logging

We have multi-casting one way messaging through a remote msmq server using wcf services for our system. One day one of our many environments got a message to multicast…and didn’t send anything out.  We have a pipeline step to audit the incoming message, topic properties to move msmq messages to a dead letter queue after a specific amount of time, and a service policy to move messages to the failed neuron db table after a specific amount of time/retries (matching the msmq network properties to…See More

Load-balancing using Neuron

I want to implement following scenario using Neuron ESB:- get big list of working items from somewhere (let's say some database)- split this list to small "batches" of working items- send these batches each to particular instance of specific subscriber (Worker), so each that instance will process assigned batch in parallel with other instances- collect feedback (is processing complete/failed) + implement some fail-over mechanism (resend failed batches, monitor if batches weren't processed…See More
