Hi,
I have a front end from where the message ise sent and is consumed by WMB for further processing and is sent to AS400 m/c i.e backend.
I have DB logging which shows that the message reached WMB and was further passed down.
How do I make the front end know that WMB consumed the messages?
I initially thought of using COA or COD, but after searching through the forums found that its not a good practice.
In what other can I make the front end notify that the message was consumed by WMB?
Thanks |

What is wrong with COD?
Or do you want to get notified only if the message was consumed successfully? Then you can send a PAN, but you must code it in the flow. After output terminal 2 of a FlowOrder node for example.
You may also want to edit the topic header and replace "Identify" with "Notify"... |

There is nothing wrong per-say with COD but will the sending system understand a COD message? That has always been the stumbling block when I've suggested this in the past.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

The problem where the original message turns up but the COD gets delayed on the back leg causing the original system to believe delivery has not taken place & initate some kind of retry. Duplicate messages and other tangles rapidly become possible.
If all you want is logging, i.e. the front end system is correctly reling on assured delivery, it's not a bad option.
