Chapter 4. Red Hat Business Optimizer changes in Red Hat Decision Manager 7.0

Red Hat Business Optimizer is an embeddable planning engine in Red Hat Decision Manager that optimizes planning problems. Red Hat Business Optimizer is based on the community OptaPlanner project that is regularly updated and in some cases requires code changes for the latest Red Hat Business Optimizer features. For an overview of the latest OptaPlanner changes and migration requirements, see the OptaPlanner upgrade recipe archive. OptaPlanner upgrade information for versions 7.0 through 7.6, inclusive, is relevant for upgrading from Red Hat JBoss BRMS 6.4 to Red Hat Decision Manager 7.0.

In Red Hat Decision Manager 7.0, certain Red Hat Business Optimizer configurations in Decision Central must be updated to accommodate recent OptaPlanner changes.

4.1. Updating Red Hat Business Optimizer asset configurations in Decision Central

If you have any solver configuration assets (.solver.xml files) or solution-related data objects in Decision Central, you must make certain updates to these assets in Red Hat Decision Manager 7.0 to accommodate recent Red Hat Business Optimizer changes.

Prerequisite

Decision Central data has been migrated from Red Hat JBoss BRMS to Red Hat Decision Manager 7.0. For migration instructions,see Chapter 2, Migrating projects in Decision Central.

Procedure

  1. Log in to Decision Central for Red Hat Decision Manager 7.0.
  2. Go to Menu → Design → Projects and select the project name.
  3. Open any solver configuration asset (.solver.xml file), if present.
  4. In the solver configuration designer, click Save without making any changes. This step is required to generate the new code for solver configuration assets in Red Hat Decision Manager 7.0. Do this step with any other solver configuration assets.

  5. Under Data Objects in the Project Explorer (left menu), open any data object (.java file) configured as a Planning Solution, if applicable.

    To verify if this setting is selected for this data object, click the OptaPlanner icon on the right side of the data objects designer. If Planning Solution is not selected, then this procedure does not apply.

  6. Under general properties in the data objects designer, set the Superclass drop-down option to Nothing selected. This setting is no longer required by Red Hat Business Optimizer in Red Hat Decision Manager 7.0.
  7. On the right side of the data objects designer, click the OptaPlanner icon to reveal the Planner Settings. The Planning Solution option should be selected (if not, then this procedure does not apply).
  8. Select No selected, then re-select Planning Solution and specify the Solution Score Type. This step is required to generate the new code for planning solutions in Red Hat Decision Manager 7.0.
  9. Click Save in the data objects designer and make the same changes to any other data objects configured as a Planning Solution.
