Hi @jaroslav.runstuk 

Check the oracle queue FND_TRK_LU_DMO_Q is enabled and subscribed to the FND_TRK_LU_DMO_Q_TAB

If the message queue is working, Queue Message Count should be 0.

If you see any queued messages, then try to stop the queue and start again.

Hope it helps!

Hello!

I do have a similar issue, so excuse me to ask your help here instead of asking a new question. 

• I do have the FND_TRK_LU_DMO_Q is enabled and subscribed to the FND_TRK_LU_DMO_Q_TAB.

• 

• I subscribed to get notifications and email for an order.

• 

• I expected to find some details in the Oracle Queue Subscribers for the 

  FND_TRK_LU_DMO_Q Queue but I found nothing at this point.

• So, I added a subscriber implicitly using the Pl/SQL code. 
  
  DECLARE
      subscriber sys.aq$_agent;
  BEGIN
      -- Create the subscriber object
      subscriber := sys.aq$_agent('SubscriberName', NULL, NULL);  -- Replace with the actual agent address
      -- Add the subscriber to the queue
      DBMS_AQADM.ADD_SUBSCRIBER(
          queue_name => 'FND_TRK_LU_DMO_Q',  -- Replace with the actual queue name
          subscriber => subscriber
      );
  END;
   

• Excuse my ignorance about the subject but I’m so confused what should the SubscriberName to represent - i.e. DB Username, IFS Application Username, the Entity Name, … - 

• I’m also not sure about submitting NULLS as the Agent’s Address and Protocol. 

• So, I used pervious code to add subscribers for the different types I’m confused about DB Username, IFS Application Username, the Entity Name,

• 

• I still get NO Notifications at all in the application nor Emails.
• I tried different user types _ App Owner, End Users,… - with all different scenarios in the subscriptions and still get nothing. 

I really appreciate your help as you both seem so familiar with the subject providing advice, or any reference documentations. 

Thank you so much.
