I am running the following configuration:
WebSphere Message Broker Toolkit - Message Broker
Version: 7.0.0.2
Build id: 7.0.0.2-20101130_1524
I am trying to configure a Collector node, but I get a bunch of issues to get it configured to work for me.
I have the following design:
From the MQInput, I store some variables, then (from the e-sql) I propagate to a number of labels (5) - one after the other. The labels connect to Sub-Flows that calls Web Services.
From the Output Terminal of the 5 Sub-Flows, I try to configure the Collector Node as such:
BASIC TAB - 5 terminals (IN1 - IN5), Correlation Name: DEALCORR, Collection Expiry: 45.
ADVANCED TAB - Non-persistent, Enabled
But when I eventually get this deployed, in the debugger, I see the Sub-Flows executing, but then nothing happens after the Collector Node.
Is there some configuration I am missing? |

You can't use the debugger to step over the Collector node.
You should be able to set a breakpoint on one of it's out terminals and have that work. |

mqjeff,
Thanks for the reply - my attempt here is to get to some kind of pattern that gives me, if not true parallel processing, at least 'overlap' processing. In other words, the call to any subsequent Sub-Flow shouldn't wait for the previous Sub-Flow to finish.
I believe there is a true way to get to pure parallel processing, but I am battling to get a pattern to work.

Collector node certainly doesn't do what you want it to do. It would allow you to assemble the results of your parallel processing, but not to perform parallel processing.
You need to do this:
MQInput--->Compute--(propagate 5 times)->MQOutput->(MQInput2)
MQInput2-->Route-(one of five)->SubFlow->Collector
Collector--->Rest of your flow logic |
