Setting the event coordination property

Use the Event coordination property for controlling how message collections are propagated from the Collector node.

Before you start:

To complete this task, you must have completed the following tasks:

In addition to the dynamic input terminals that you can add to the Collector node, there is a static input terminal called Control. The purpose of this terminal is to allow an external resource to trigger the output from the collector node. Details are controlled via the Event coordination property settings.

To configure Event coordination:

  1. Switch to the Broker Application Development perspective.
  2. Open the message flow with the Collector node.
  3. Right-click the Collector node and select Properties.
  4. Click on the Basic tab.
  5. Set the Event coordination property on the Collector node. Select from the following options:
    • If you select Disabled, messages to the Control terminal are ignored and message collections are propagated when they are complete.
    • If you select All complete collections, complete message collections are held on a queue. When a message is received on the Control terminal, all message collections on the queue are propagated to the Out terminal.
    • If you select First complete collection, complete message collections are held on a queue. When a message is received on the Control terminal, the first message collection on the queue is propagated to the Out terminal. If the queue is empty when a message arrives on the Control terminal, the next message collection that is completed is propagated to the Out terminal.
You have completed configuration of the Collector node.
Next: if you have configured your Collector node to use control messages, see Using control messages with the Collector node.
