Chapter 3. Technical preview

This section lists features that are in technical preview in Red Hat Decision Manager 7.0. You will see the following note where technical preview features are referred to in the documentation:

Important

These features are for Technology Preview only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend to use them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For more information on Red Hat Technology Preview features support scope, see https://access.redhat.com/support/offerings/techpreview/.

3.1. Technical Preview features

  • Aliases - You can use aliases instead of container IDs in the remote REST APIs of the Planner Server.
  • Application Lifecycle Automation - Part of Red Hat Decision Manager and disabled by default.
  • Content Management System (CMS) Perspective - Part of Red Hat Decision Manager and disabled by default.
  • OpenShift Container Platform - Comprised of the Decision Server, Planner Server, and Decision Central.
  • Provisioning User Interface - Enables you to provision a server on OpenShift while running the selected project build from Decision Central. It is part of Red Hat Decision Manager and disabled by default.

  • Predictive Model Markup Language (PMML) - The PMML feature is fully implementated for the following predictive model types:

    • Decision Tree
    • Regression

    • Scorecard

      PMML has a partial implementation of the Mining Model type; with the following model sub-types available:

    • Select All
    • Select First
    • Model Chaining

3.2. Technical Preview experimental features

The following Technology Preview features are experimental and may require additional API changes:

  • Multithreaded Execution - Solves a single data set by partitioning across multiple threads. It is turned off by default and can be enabled either with a KieBaseConfiguration option or with a system property as explained in Drools Documentation
  • Rule Units - Rule Units represent a declarative approach to partitioning a rule set in to smaller units, binding different data sources to those units, and the execution of the individual unit. A Rule Unit is comprised of data sources, global variables, and rules.

3.2.1. Enabling Application Lifecycle Automation and Provisioning User Interface

Red Hat Decision Manager settings allow you to enable the Application Lifecycle Automation and Provisioning User Interface features.

  1. Go to Settings → Roles → admin.
  2. Expand Pages and click the Read field to enable Deployments.

3.2.2. Enabling the Content Management System (CMS) Perspective

Red Hat Decision Manager settings allow you to enable the CMS Perspective.

  1. Go to Settings → Roles → admin.
  2. Expand Pages and click the Read field to enable Page Authoring.

3.2.3. Enabling Predictive Model Markup Language (PMML)

This feature uses a single configuration option, org.drools.compiler.compiler.PMMLCompiler. The valid values for this configuration option are:

  • org.kie.pmml.pmml_4_2.PMML4Compiler - This value should be used for the majority of cases where PMML support is desired.
  • org.drools.pmml.pmml_4_2.PMML4Compiler - This value provides backwards compatibility, and should only be used in cases where there is a reliance on the older drools-pmml and drools-scorecards modules.
