Overriding data source properties

Edit online

Optionally, you can associate a policy with a manufacturing node to override the data source configuration properties of message flows and message flow nodes at run time.

Before you begin

This task assumes that you have already created a policy project for the required manufacturing nodes.

Ensure that you have read the guidelines for creating policies.

About this task

You can associate a policy project with the manufacturing message flow nodes. Policy documents can be deployed to IBM App Connect as part of a BAR file. You create one or more policies in a policy project.

Policies are XML files; therefore, you can create a policy by using an XML editor.

You can add the policy project name for the following built-in nodes:
  • OPC-UA-Input
  • OPC-UA-Read
  • OPC-UA-Write
  • OP-UA-Method-Call

Procedure

  1. Click the Manufacturing drawer from the Palette view.

    The Manufacturing drawer list the available built-in nodes.

  2. Drag the node from the Manufacturing drawer list for which you want to add a policy project to the Flow Exerciser.
  3. From the node Properties view, click the Policy tab.

    The Policy property page loads.

  4. Specify the Policy Project name that you want to use for the particular manufacturing node.
    Note: By default, if there is no any policy project name specified in the policy property of a OPC UA node, it would take the policy name that is specified in the server.conf.yaml file.
