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.
