Flow 1: Design and Distribute First Control Loop

Testing Directions

Log into SDC as designer (cs0008)

Create a service

In Composition, create a resource instance in the service

On the composition canvas, click on the resource instance

On the panel on the right, click on the second tab (Deployment Artifacts)

Click "Add Artifact"

Assign values to the artifacts as in the below screenshot, and upload the provided blueprint.

Submit the Service for Testing

Log in as a Tester user (jm0007)

Test the Service and Approve It

Log in as a Governance User (gv0001)

Approve Service for Distribution

Log in as Operations User (op0001)

Distribute Service

Monitor Service to see that both DCAE and Clamp clients have successfully deployed the artifact

Flow 2: Configure and Deploy First Control Loop

Image Removed

Testing Directions

Log into CLAMP using credentials admin/password

Select Open CL from Closed Loop Menu

You will find the Closed Loop model that has been distributed from SDC.  Its name has the form: CLAMP + <Service name> + <version> + <resource name>.  For example, below there is a closed loop model for serivce 'intsrv1', version 1.0 and resource vLBMS0.

Image Removed

This will bring up a view of the control loop model.  This allows you to create the TCA configuration policy and Operational Policy.

Image Removed

Fill in the details of the Operational Policy by clicking on Policy

Image Removed

Fill in the details of the Configuration Policy by clicking on TCA

Choose Save CL from Closed Loop Menu

Choose Submit from Manage Menu

Choose Deploy from Manage Menu

Choose Save CL from Closed Loop Menu

Choose Submit from Manage Menu

The Status will change to "Distributed"

Choose Deploy from Manage Menu

This may take on the order of tens of seconds, as it waits for DCAE to report final success.

Once the Deployment is successful in DCAE, Status will change to "Active"
