Operation Orchestration Service (OOS) allows you to delete an execution in a final status. If the execution to be deleted is in a non-final status, such as Waiting or Running, you need to cancel the execution before deleting it.
- Log on to the Elastic Compute Service (ECS) console. Choose Maintenance & Monitoring > Operation Orchestration Service in the left-side navigation pane.
- Click the Executions tab.
- Find the execution to be deleted, and then click Delete in the Actions column.
- In the Delete Execution dialog box that appears, click OK.
