Issue/Introduction

In VMware Telco Cloud Automation (TCA), CNF workflows fail to execute immediately. The failure occurs at the initial "Clean up" step with no visible logs or subtasks in the UI.

Log analysis reveals a java.lang.RuntimeException within the VroService thread indicating that the workflow cannot find the necessary orchestration configuration.

Symptoms:

  • Workflows fail at ~10% completion during the first step.
  • No workflow history or subtask details are available in the TCA manager.
  • Logs contain the following error in the tca-cp-cn_tca-app logs :

    Caused by: java.lang.RuntimeException: VRO configuration not found : Please add vRealize Orchestrator to TCA-CP appliance. Contact System Administrator for more help

Environment

TCA build : 3.2, 3.3, 3,4
TCP : 5.0, 5.0.1, 5.1

Cause

The TCA-CP (Control Plane) appliance is not configured with a vRealize Aria Orchestrator (vRO) registration, preventing the execution of SSH-based guest commands required for CNF recipes.

Resolution

To resolve this issue, register the vRealize Aria Orchestrator with the TCA-CP appliance:

  1. Log in to the VMware Telco Cloud Automation-Control Plane (TCA-CP) appliance management interface.

  2. Navigate to the vRealize Orchestrator configuration section.

  3. Add the details for your vRealize Aria Orchestrator instance.

  4. Verify the connection status shows as healthy.

  5. Re-run the CNF workflow to confirm the "Clean up" step completes successfully.
