Chapter 2. New features

For complex DMN models, you can now use the DMN designer in Business Central to design multiple DMN decision requirements diagrams (DRDs) that represent parts of the overall decision requirements graph (DRG) for a DMN decision model. This improvement enables you to better organize DMN decision models with many decision requirements by dividing the model into smaller nested DRDs.

For more information about creating DMN models with multiple diagrams, see Designing a decision service using DMN models.

Dashbuilder runtime is a new add-on standalone web application, distributed as a WAR to run the dashboards on Red Hat JBoss EAP. If you have access to dashbuilder runtime, you can explore the dashboards created in Business Central. The following list provides a summary of dashbuilder runtime updates:

The following list provides a summary of process designer updates:

For more information, see Designing business processes in Business Central.

You can now use link events in the process designer to connect different parts of your process. The new link events include an intermediate throwing and catching link event. For more information, see Designing business processes in Business Central.

You can now directly add email addresses to send task notification emails. For more information, see Designing business processes in Business Central.

The traits functionality and its specific implementation code is moved to an individual module named drools-traits. To use traits, you can import the drools-traits module to Maven. The existing implementation is not supported in the executable rule model.

A new module named drools-metric is added, which can assist in the performance analysis of the decision engine.

For more information, see Designing a decision service using DRL rules.

You can now create a business process using the process fluent API. Following is a basic example of creating a business process using fluent API:

ProcessBuilderFactory factory = ProcessBuilderFactories.get();
Process process = factory
    // start process definition
    .processBuilder(processId)
    // package and name
    .packageName(packageName)
    .name(processName)
    .setMetadata("pepe", true)
    // start node
    .startNode(1).name("Start").done()
    // script node in Java language that prints "action"
    .actionNode(2).name("Action")
    .action(Dialect.JAVA,
            "System.out.println(\"Action\");").done()
    // end node
    .endNode(3).name("End").done()
    // connections
    .connection(1, 2)
    .connection(2, 3)
    .build();

For more information about process fluent API, see Interacting with Red Hat Process Automation Manager using KIE APIs.

Red Hat Process Automation Manager 7.9 provides enhanced search capabilities, including flexible search criteria for tasks, process instances, and cases. For more information, see Designing and building cases for case management.

You can follow the example in Creating a school timetable using Red Hat Business Optimizer with Spring Boot to create a school timetable.

The rotation pattern on the Employee Rostering Rotation window has been redesigned for ease of use. For more information, see Running and modifying the employee rostering starter application for Red Hat Business Optimizer using an IDE.

You can now replicate KIE Server audit data to a Java Message Service (JMS) message broker, for example, activeMQ or Artemis, After replicating the data, you can dump the data in an external database schema so that you can improve the performance of your Spring Boot application by deleting the audit data from your application schema.

For more information, see Creating Red Hat Process Automation Manager business applications with Spring Boot.

You can now create a PostgreSQL schema that uses the bytea column type instead of the oid column type by setting the value of the org.kie.persistence.postgresql.useBytea property to true.

For more information, see Creating Red Hat Process Automation Manager business applications with Spring Boot.

You can create a self-contained Red Hat Process Automation Manager Spring Boot JAR file that contains multiple versions of the same KJAR file.

For more information, see Creating Red Hat Process Automation Manager business applications with Spring Boot.

Red Hat Process Automation Manager now supports Red Hat OpenShift Container Platform version 4.6. In order to support this version, necessary changes in the operator bundle format are made. Red Hat OpenShift Container Platform version 4.6 provides an extended update support. For more information, see Red Hat OpenShift Extended Update Support (EUS) Overview.

When using LDAP authentication, Red Hat Process Automation Manager on Red Hat OpenShift Container Platform now supports failover to a different LDAP server if a server becomes unavailable.

For more information, see Deploying a Red Hat Process Automation Manager environment on Red Hat OpenShift Container Platform using Operators and Deploying a Red Hat Process Automation Manager environment on Red Hat OpenShift Container Platform using templates.

Red Hat Process Automation Manager on Red Hat OpenShift Container Platform now supports integration with the following new product versions:

Red Hat Process Automation Manager on Red Hat OpenShift Container Platform now supports customized Smart Router images. You can extend Smart Router to provide routing specific to the needs of your environment.

For more information, see Deploying a Red Hat Process Automation Manager environment on Red Hat OpenShift Container Platform using Operators.

You can now configure the logging level for Smart Router when deploying Red Hat Process Automation Manager on Red Hat OpenShift Container Platform.

For more information, see Deploying a Red Hat Process Automation Manager environment on Red Hat OpenShift Container Platform using Operators.

You can now deploy Red Hat Process Automation Manager on Red Hat OpenShift Container Platform using the operator with a KIE Server that is not managed by Business Central monitoring.
