Automatic configuration

After RabbitMQ has been installed, we can configure the queues, exchanges and the bindings between the exchanges and queues. A default configuration is available (definitions.json). This is a JSON file which contains all queues, exchanges and bindings necessary for the DCM setup. It can be imported in the RabbitMQ dashboard in the "Overview" tab, under "Import definitions". 

...

After importing the file it might be necessary to reconfigure the users, to add a new user so you can remove the guest user. please see: https://www.rabbitmq.com/access-control.html

Manual configuration

Its possible to configure RabbitMQ manually using the following steps:

...

* This exchange publishes to the same queue as the dcmEvents exchange.

Application properties

For each component that uses RabbitMQ, one or more queues/exchanges need be configured including the properties of the RabbitMQ instance.

...

if the property ssl.enabled is not set at all it will default to false regardless.

Case Engine

Add the following exchanges and queues to the Case Engine properties when you want to override queues and exchanges with your own:

...

blueriq.dcm.lists-publisher.rabbitmq.exchangeName=dcmListsEvents
...

Runtime

DCM Maintenance App

Add the following to the DCM Maintenance App properties  when you want to override queues and exchanges with your own:

            rabbitmq:

          listener:
            rabbitmq:
              queueNames:
