In this lesson, you will simulate using the Clips and Tacks policy.
You will use the Business Services perspective of WebSphere® Business Services
Fabric in WebSphere Integration
Developer to simulate the initial shipping policies and their impact
on the Order Handling process. Simulation allows you to run and validate
polices and assertions that are part of the initial scenario. The
initial scenario is pre-built for this sample and the Clips and Tacks
policy is ready for simulation.
The following table represents the Clips and Tacks service-provider endpoint capabilities (assertions) and the use cases for service consumers for the initial scenario. The top row depicts the available service providers, and the left column represents the service consumer use cases. The X represents the service-provider endpoint that is to be selected based on the context, content, and contract of the service consumer's request.
| Internal Shipping | Better Shipping | International Express | |
|---|---|---|---|
| Order Size = SMALL and Order Type = DOMESTIC | X | ||
| Order Size = LARGE and Order Type = DOMESTIC | X | ||
| Order Type = INTERNATIONAL | X |
The business services policies for the initial Clips and Tacks scenario were created based on this table.
To start the policy usage simulation, complete the following steps:
- Logout of Business Space if you have not done so and switch to WebSphere Integration Developer.
- Select the Business Service perspective and the Business
Service Explorer tab. Expand the Simulation node
and double-click Test Verify Shipper Selection.
- Verify the Simulation values against the screen below
and click Run. The Simulation Operations panel shows only green check marks and the InternalShippingEndpoint is selected.
When the simulation confirms that the correct policy is being
selected, it is time to try a runtime test.
