Configuring a message flow node

Before you start:

When you have included an instance of a node in your message flow, you can configure its properties to customize how it works. The node can be a built-in node, a user-defined node, or a subflow node. You can choose whether the properties appear in the Properties view below the Message Flow editor, or in the Properties dialog box. By default, properties are shown in the Properties view. To switch to the Properties dialog box, take the following steps:

  1. Click Window > Preferences to open the Preferences dialog box.
  2. Expand Broker Development and click Message Flow Editor.
  3. Select Show node properties in a Properties Dialog.

Viewing a node's properties

To view a node's properties:

  1. Switch to the Broker Application Development perspective.
  2. Open the message flow with which you want to work.
  3. Click Selection above the node palette.
  4. Right-click a node and click Properties to open the Properties view or Properties dialog box. Alternatively, you can double-click the node to display its properties.

Editing a node's properties

Properties are organized into related groups and displayed on tabs. Each tab is listed on the left of the Properties view or Properties dialog box. Click each tab to view the properties that you can edit.

For details of how to configure each individual built-in node, see the node description. You can find a list of the nodes, with links to the individual topics, in Built-in nodes.

Promoted properties

You can promote node properties to their containing message flow. Use this technique to set some values at the message flow level, without having to change individual nodes. This can be useful, for example, when you embed a message flow in another flow, and want to override some property such as output queue with a value that is correct in this context.

Overriding properties at deploy time

A small number of node property values can be overridden when a message flow is deployed. These are known as configurable properties, and you can use these to modify some characteristics of a deployed message flow without changing the message flow definitions. For example, you can update queue manager information.

Even though you can set values for configurable properties at deploy time, you must set values for these properties within the message flow if they are mandatory.
