Chapter 9. Configuring the environment mode in Process Server and Business Central

You can set Process Server to run in production mode or in development mode. Development mode provides a flexible deployment policy that enables you to update existing deployment units (KIE containers) while maintaining active process instances for small changes. It also enables you to reset the deployment unit state before updating active process instances for larger changes. Production mode is optimal for production environments, where each deployment creates a new deployment unit.

In a development environment, you can click Deploy in Business Central 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 stop any running 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 in Business Central is disabled and you can click only Deploy to deploy the built KJAR file to a new deployment unit (KIE container) on a Process Server.

Procedure

  1. 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.
  2. To configure the deployment behavior for a project in Business Central, go to project SettingsGeneral SettingsVersion and toggle the Development Mode option.

    Note

    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.
