Process for Running Order-related Requests Using EMS
This section explains the process for routing and running order-related requests using TIBCO Enterprise Messaging Service (EMS).
-
After receiving an order-related request, the system first identifies the instance ID (also known as instance_id) associated with the order.
-
The request is then dispatched to EMS. It includes a JMS header named originator, with the instance ID specified as its value.
-
The owner instance listens for this request by creating a listener with a selector matching the originator value.
-
The owner instance proceeds with processing the request as required.
When making requests to southbound systems, the system includes a header named originator, with the instance ID as its value, in one of the following ways:
-
For requests sent through EMS, the system includes this information in the JMS header.
-
For requests made through REST, the system includes this information in the HTTP Request header.
