Chapter 1. Example projects and business assets in Business Central

Business Central contains example projects with example business assets that you can use as a reference for the rules, processes, or other assets that you create in your own Red Hat Process Automation Manager projects. Each sample project is designed differently to demonstrate process automation, decision management, or business optimization assets and logic in Red Hat Process Automation Manager.

Note

Red Hat does not provide support for the example code included in the Red Hat Process Automation Manager distribution.

The following example projects are available in Business Central:

  • Evaluation_Process: (Process automation) Example evaluation process using business process assets. Evaluates employees based on performance.
  • Mortgage_Process: (Process automation) Example loan approval process using business process and decision assets. Determines loan eligibility based on applicant data and qualifications.
  • IT_Orders: (Process automation and case management) Example ordering case using business process and case management assets. Places an IT hardware order based on needs and approvals.
  • Traffic_Violation: (Decision management with DMN) Example traffic violation decision service using a Decision Model and Notation (DMN) model. Determines driver penalty and suspension based on traffic violations.
  • Mortgages: (Decision management with rules) Example loan approval process using rule-based decision assets. Determines loan eligibility based on applicant data and qualifications.
  • Employee_Rostering: (Business optimization) Example employee rostering optimization using decision and solver assets. Assigns employees to shifts based on skills.
  • OptaCloud: (Business optimization) Example resource allocation optimization using decision and solver assets. Assigns processes to computers with limited resources.
  • Course_Scheduling: (Business optimization) Example course scheduling and curriculum decision process. Assigns lectures to rooms and determines a student’s curriculum based on factors, such as course conflicts and class room capacity.
  • Dinner_Party: (Business optimization) Guest seating optimization using guided decision tables. Assigns guest seating based on each guest’s job type, political beliefs, and known relationships.

1.1. Accessing example projects and business assets in Business Central

You can use the example projects in Business Central to explore example business assets as a reference for the rules or other assets that you create in your own Red Hat Process Automation Manager projects.

Prerequisites

Procedure

  1. In Business Central, go to MenuDesignProjects and click Try Samples.

    If a project already exists, click the three vertical dots in the upper-right corner of the Projects page and click Try Samples.

  2. Review the descriptions for each sample project to determine which project you want to explore. Each sample project is designed differently to demonstrate process automation, decision management, or business optimization assets and logic in Red Hat Process Automation Manager.
  3. Select one or more sample projects and click Ok to add the projects to your space.
  4. In the Projects page of your space, select one of the new example projects to view the example assets for that project.
  5. Select each example asset to explore how the project is designed to achieve the specified goal or workflow.
  6. In the upper-right corner of the project Assets page, click Build to build the sample project or Deploy to build the project and then deploy it to Process Server.

    Note

    You can also select the Build & Install option to build the project and publish the KJAR file to the configured Maven repository without deploying to a Process Server. In a development environment, you can click Deploy to deploy the built KJAR file to a Process Server without stopping any running instances (if applicable), or click Redeploy to deploy the built KJAR file and replace all instances. The next time you deploy or redeploy the built KJAR, the previous deployment unit (KIE container) is automatically updated in the same target Process Server. In a production environment, the Redeploy option is disabled and you can click Deploy only to deploy the built KJAR file to a new deployment unit (KIE container) on a Process Server.

    To configure the Process Server environment mode, set the org.kie.server.mode system property to org.kie.server.mode=development or org.kie.server.mode=production. To configure the deployment behavior for a corresponding project in Business Central, go to project SettingsGeneral SettingsVersion and toggle the Development Mode option. By default, Process Server and all new projects in Business Central are in development mode. You cannot deploy a project with Development Mode turned on or with a manually added SNAPSHOT version suffix to a Process Server that is in production mode.

    To review project deployment details (if applicable), go to MenuDeployExecution Servers.
