Adding Pipeline Pair Nodes to Message Flows

Message flows can include zero or more pipeline pair nodes: request and response pipelines for the proxy service (or for the operations on the service), and error handler pipelines that can be defined for stages, pipelines, and proxy services. pipelines can include one or more stages, which in turn include actions.

Before you begin

These instructions assume you are already editing a message flow in the Edit Message Flow page, as explained in Creating, Editing, and Viewing Message Flows.

To add a Pipeline Pair node to a message flow

  1. Click the  Proxy Service icon, then click Add Pipeline Pair.
  2. To change the default name and add a description for the pipeline pair node, do the following:
    1. Click the  Pipeline Pair Node icon, then click Edit Name and Annotation.
    2. Change the name and description, as desired.
    3. Click Save.
    4. Note: When you rename a pipeline or a route node, the number of messages displayed on the Dashboard page in the Monitoring module may not correlate with those of other components due to the pipeline counters being reset to zero. This is because ALSB treats the rename as a delete and recreate action. The numbers should correlate again after a time period equal to the service's monitoring interval has elapsed.
  3. To add stages to the pipeline, see Adding Stages to Pipelines
  4. To add actions to stages in the pipeline. See Adding and Editing Actions in Message Flows
  5. On the Edit Message Flow page, continue to construct the message flow, as described in Creating, Editing, and Viewing Message Flows.
  6. Click Save to commit the updates in the current session.
  7. To end the session and deploy the configuration to the run time, click Activate under Change Center.
