You are viewing the documentation for Blueriq 16. Documentation for other versions is available in our documentation directory.
The Case Engine manages all operations on cases, case data and tasks. It communicates with the Blueriq Runtime through asynchronous messages and a REST API.
The Case Engine is essential to use the event driven DCM architecture and depends on multiple other components to function properly.
This section explains how to install the Case Engine, how to configure it and which other components are needed to be installed.
Installation
The Case Engine currently is a Runtime with specific configuration. It is installed by deploying the Runtime WAR to a supported application server, see Installing Runtime. Alternatively you can use the Blueriq DCM Development Installation which includes the case engine with configuration.
Dependencies
The Case Engine depends on the following components:
- Audit component
- DCM Lists Components
- Timeline SQL Store component
- Trace SQL Store component
- DCM queueing
- Document database MongoDB
- Customerdata service
- Process SQL store component
- Case Engine Scheduler
- Case Engine Scheduler Quartz
The bootstrap.properties
file needs to have the following content to enable these profiles:
spring.profiles.active=native,\ case-engine,\ customerdata-client,\ dcm-lists-publisher,\ externaldatasources,\ process-sql-store,\ timeline-event-publisher-amqp,\ trace-event-publisher-amqp,\ audit
Configuration
Specific for the case engine there are multiple properties that need to be set.
These properties are divided into three files:
application.properties
: common properties that concern security, logging and the connection to the customer dataapplication-
: properties for several queues, MongoDB and Quartzcase-engine
.propertiesapplication-
: properties that enable the Case Engine to communicate with the Process SQL Storeexternaldatasources
.properties
Create the files in the additional config location of the case engine and copy and paste the corresponding properties into each file.
When using the Blueriq DCM Development Installation this configuration is included

Authentication
The synchronous operations are protected with basic authentication. To specify the credentials required to log in to the Case Engine, create a user in user.properties
with the case-engine
role.
#format: USERNAME=PASSWORD,PRIVILEGE1,PRIVILEGE2,... #example: admin=welcome,agent,customer,underwriter # User for Case Engine caseengine={noop}caseengine,case-engine
If you are using a different authentication provider, like LDAP, you can create a user in that provider instead of users.properties
, as long as it has the proper role.
Event logging
It is possible to enable logging for events sent to the Case Engine. A line is logged when the Case Engine starts processing the event and when it is finished.
Events list
- AbortTaskService
- AbortTaskWithoutUnlocking
- AssignTask
- CompleteTask
- CreateCase
- DemuxedThrowMessageEvent
- GetCaseInfo
- GetTaskInfo
- RemoveCase
- ScheduledEvent
- StartTask
- ThrowMessage
How to enable
By default, the events are logged on INFO level. To specifically enable logging for the events only, configure the following package on INFO level:
logging.level.com.blueriq.dcm.caseengine.service=INFO
Example output
StartTask event:
Finishing a case
Whenever the process for a case finishes, the case will be closed. This means that the following persistent parts of a case will be removed:
- The process and its tasks and data in the process-sql-store
- The case and its manual tasks in the DCM Lists Service's MongoDB database
- The case document in MongoDB
- Any remaining entries in the scheduler database
- The case aggregate and the case data aggregate
We are aware that it may not be desirable to remove the aggregates, for example if your process doesn't have steps for archival. Therefore, we introduced a property to control this behavior:
blueriq.case.engine.data.general.remove-aggregates-on-case-close = false
The default value for this property is true
