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.
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.
The Case Engine depends on the following components:
The 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 |
Specific for the case engine there are multiple properties that need to be set.
These properties are divided into three files:
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 |
### Users ### blueriq.security.auth-providers.local01.type=in-memory blueriq.security.auth-providers.local01.users.location=users.properties blueriq.security.auth-providers-chain=local01 ### Customerdata ### blueriq.customerdata-client.url=http://localhost:30002/customerdata/api/v1/ blueriq.customerdata-client.username=blueriq blueriq.customerdata-client.password=welcome ### Exports ### blueriq.exports.description=Exports blueriq.exports.prefix=export blueriq.exports.folder=exports blueriq.exports.enabled=true ### Security settings ### blueriq.security.csrf-protection.enabled=false ### Blueriq logging ### #logging.level.com.aquima=DEBUG #logging.level.com.blueriq=DEBUG logging.file.name=logs/case-engine.log ### Default Queue configuration, can be ommitted when overruled at specific configuration in application-case-engine.properties ### blueriq.default.rabbitmq.host=localhost blueriq.default.rabbitmq.port=30010 blueriq.default.rabbitmq.username=guest blueriq.default.rabbitmq.password=guest blueriq.default.rabbitmq.virtualHost=/ blueriq.default.rabbitmq.ssl.enabled=false |

#### Datasources PostgreSQL ### blueriq.datasource.process-sql-store.url=jdbc:postgresql://bq-postgres:5432/blueriq blueriq.datasource.process-sql-store.username=blueriq blueriq.datasource.process-sql-store.password=welcome blueriq.datasource.process-sql-store.driverClassName=org.postgresql.Driver hibernate.process-sql-store.hbm2ddl.auto=validate |
When using a production database, please use 'validate' instead of 'update' in combination with the supplied database scripts. |
# queue configuration from blueriq.default.rabbitmq can be overruled blueriq.dcm.lists-publisher.rabbitmq.exchangeName=dcmListsEvents |
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.
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.
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 |
StartTask event logline:
2024-04-25 13:43:09.100 INFO c.b.d.c.c.CaseEngineRestController httpSessionId="43C5CF48C812F97E301843659A09A04A" runtimeSessionId="" userId="caseengine" projectName="" projectVersion="" currentPageName="" tenantName="" [trace=662a41cd99970f5e778c9835294b1413,span=be8f45537809ead6] - [startTask] Starting transaction - task ID: '6' case ID: '662a41c4fcab766683cab7c5'
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:
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
.
