Third party tools
RabbitMQ
The DCM Lists Service receives events from the Blueriq Runtime application via the RabbitMQ Messaging system (see DCM queueing). The DCM Lists Service should be able to connect to the RabbitMQ instance.
MongoDB
The DCM Lists Service stores its data in MongoDB (see Document database MongoDB). The DCM Lists Service should be able to read and write data into a MongoDB instance.
Place these tools on their own dedicated server, with sufficient resources. We refer to the websites of MongoDB and RabbitMQ for advice on hardware requirements for these components.
Configuration
The DCM Lists Service requires a blueriq-dcm-lists.yml
file in the spring.config.additional-location
blueriq: dcm: lists: mongodb: host: mongodb.yourdomain.local port: 27017 database: DcmListsService username: youruser password: yourpass event: consumer: rabbitmq: # can be used to override queue configuration from blueriq.default.rabbitmq setting and default queueNames queueNames: dcmListsServiceEventsQueue errorExchange: dlx.dcmListsServiceEvents concurrency: # can be used to tune the queue consumption on high load.
