Dispatcher pipeline not enabled in Cloud Manager Adobe Experience Manager as a Cloud Service
In Adobe Experience Manager (AEM) as a Cloud Service, the dispatcher/web-tier pipeline cannot be triggered when another pipeline is already running for the same environment. Cloud Manager shows the affected environment with a Pipeline Running status until the existing pipeline reaches a terminal state.
This article explains why the dispatcher pipeline is not enabled and how to resolve the issue.
Description description
Environment
Adobe Experience Manager as a Cloud Service (all versions)
Issue/Symptoms
- The dispatcher/web-tier pipeline cannot be triggered for deployment (for example, during an update).
- Cloud Manager UI shows the relevant environments (such as production and stage) with the status Pipeline Running (not a terminal state).
- Attempting to trigger a new dispatcher pipeline is blocked, pausing release activities and impacting the planned deployment schedule.
- No production outage or customer-facing unavailability is reported, but deployment is blocked.
Cause
Cloud Manager does not allow triggering a new dispatcher/web-tier pipeline for an environment while another pipeline is still running for that environment. The previous pipeline must reach a terminal state (completed or cancelled) before a new pipeline can be started.
Resolution resolution
Follow the steps below to resolve the issue.
- In Cloud Manager, verify whether any pipeline (full-stack or web-tier) is currently running for the target environment (Production or Stage).
- If a pipeline is running, wait until it reaches a terminal state (such as Completed or Cancelled). Pipelines may remain in a running state if manual steps, such as production approval, are pending.
- Ensure that all required approvals are completed, or cancel the pipeline if it is no longer needed.
- Once the previous pipeline reaches a terminal state, the dispatcher/web-tier pipeline becomes enabled and can be triggered for deployment.
- For more details about pipeline behavior, refer to the official Adobe documentation.
