- Connect to Consul: http://<Cluster IP><ANY K8S VM IP ADDRESS>:30270 and click on "Key/Value" → "dcae-tca-analytics"
- Change "eventName" in the vLB default policy to something different, for example "vLB" instead of the default value "vLoadBalancer"
- Change "subscriberConsumerGroup" in the TCA configuration to something different, for example "OpenDCAE-c13" instead of the default value "OpenDCAE-c12"
- Click "UPDATE" to upload the new TCA configuration

- Connect to the Policy GUI, either through the ONAP Portal (https://portal.api.simpledemo.onap.org:30225/ONAPPORTAL/login.htm) or directly (https://policy.api.simpledemo.onap.org:30219/onap/login.htm)
- If using the ONAP Portal, use demo/demo123456! as credentials, otherwise, if accessing Policy GUI directly, use demo/demo

distributing the closed loop from CLAMP to policy if we get error as - policy send failed PE300: Invalid template, the
...
template name closedLoopControlName was not found in the dictionary.
For proper operation via CLAMP, the rules template need to be uploaded to Policy. This can be achieved by executing the push-policies.sh script before creating the Control Loop via CLAMP:
kubectl get pods -n onap -o wide | grep policy | grep pap # identify the PAP pop
kubectl exec -it <pap-pod> -c pap -n onap -- bash -c "/tmp/policy-install/config/push-policies.sh"
Resolution: Replace the "input" field in the JSON template with "output"
- Connect to the SDNC container from the Rancher VM in the Kubernetes cluster, for example kubectl exec -it -n onap dev-sdnc-sdnc-0 bash
- Install your favorite text editor, for example apt-get update; apt-get install vim -y
Open /opt/onap/sdnc/restapi/templates/lcm-dmaap-publish-template.json and replace "input" with "output" in the JSON object body
Save the changes
If SDNC is deployed in cluster mode (3 SDNC replicas, dev-sdnc-sdnc-0, dev-sdnc-sdnc-1, dev-sdnc-sdnc-2), apply the same change to all the replicas in the cluster
