Clearing Stuck Queues

Dispatcher Flush Queues (on Publishers)

Dispatcher Flush queues exist on publisher nodes (cmsa-<tier>-02 and -03) and are the mechanism by which AEM tells the Dispatcher (cache tier) that a new version of a page is available).

1. Log in to CRX/DE on each publisher node
2. system/console/bundles https://cmsa-prod-02.db.vt.edu/system/console/bundles
3. Search for "Adobe Granite Replication (com.day.cq.cq-replication)"
4. Stop the bundle (VCR-style square button)
5. Wait until the status says "Resolved"
6. Start the bundle (VCR-style play button)
7. The status should now be "Active"

Publish Queues (on Author)

• There are two publish queues - one for each publisher, creatively named publish-02 and publish-03.
• Visual indication of queue length and performance on the AEM Author Dashboard Requires VT PID
• Queued item details: publish-02 and publish-03 Requires admin privilege on AEM

If there is a large item stuck in the queue

1. Determine the queue id of the stuck item with these links
2. publish-02 replication queue
3. publish-03 replication queue (should be the same item as publish-02)
4. This should produce a JSON output simliar to the output below

5. The first item is usually the one blocking the queue (and it will be large)

6. Find the queue.id value ("2017/9/25/13/21/b5508619-1f17-49a2-9a0f-27d84716ee9b_92596" in this example)

7. Switch to CRX/DE and log in if necessary (your normal session should carry over)
8. Locate /var/eventing/jobs/assigned//com.day.cq.replication.job.publish-02
9. Find the path corresponding to the queue.id you found above
10. Right-click and select "Delete"
11. Click "Save All" (top-left corner)
12. Repeat for /var/eventing/jobs/assigned//com.day.cq.replication.job.publish-03
