When you have included an instance of a node in your message flow, you can configure it to customize its function. The node can be a built-in node, a user-defined node, or a subflow node.
Before you start
To complete this task, you must have completed the following task:
To configure a node:
If the node only has Description properties (for example, the FlowOrder node), these are initially displayed when you open the properties dialog.
For most other nodes, the Basic properties are initially displayed. A few nodes (for example, MQeInput) do not have Basic properties; for these, the first group is displayed.
For example, the Basic properties of the MQInput node include just one property, Queue Name. This identifies the queue from which input messages are retrieved by the node, and is a required property. On the properties dialog, it appears like this:
Queue Name* ________________________________
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.
If you have included a user-defined node, refer to the documentation that came with the node to understand if, and how, you can configure its 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 or data source with a value that is correct in this context.
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 and data source 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.
