Guys,
I am running WMB 7.0.0.2.
I am attempting to use the Collector Node and I have set it up with two MQ queues feeding into two terminals created on the Collector Node.
The properties on the 'Basic' tab I have set up with a Correlation path as '$Root/MQMD/CorrelId' - for both input terminals.
So, I am expecting that the Collector Node will collect the first message, start a new collection, wait for the second message, and if the 2nd message matches the Correlation Id of the 1st message, complete the collection and spit it out on the Out terminal to be processed further.
But, it doesn't matter what my Correlation Id is set to, the collection completes once it received *any* two message, regardless of the Correlation Id of the messages.
Obviously I am missing something somewhere....
Thanks |

Why 2 input terminals?
Each collection is unique to the input terminal you've defined. So if you have a Collector node with an input terminal A set as you've described, and another input terminal B likewise then the first 2 messages with the same correl id that arrive on A within the collection expiry should come out as a collection called A. Likewise on B.
If 1 message arrives on A, and another arrives on B with the same correl id you should get 2 collections started, both of which should come out of the expiry terminal after expiry.
Are you sure your messages are a) in the same collection and b) emitting from the Out terminal not the expire terminal?
Also what do you have the collection name set to? If it's blank that may be disgusing the fact these messages are in 2 different collections. Try * to name them for their handler.

Ok, so you are saying if I configure the collector node with an input terminal (IN1), and I expect to get 2 messages from different queues (Q1 and Q2), these queues should be connected to the terminal IN1 for it to constitute a collection? If this is the case, then I have mis-intrpreted it completely.
Thanks for your reply. |

You should get 2 messages in a collection called IN1 (if you use * in the collection name).

No problem.
I suffer from the same problem sometimes.
