The purpose of this kit is to provide the means to get started with the Red Hat Decision Manager (RHDM) product, from introduction, to installation, to using the product to build a first application.

It will present the available content in a logical order, providing a learning path for first time users. With the video tutorials designed to be non-specific to a version, these initial steps will save you time spinning up your first process application or project. Just follow the numbered steps below and you will be on your way to mastering Red Hat Decision Manager.

This starters kit is currently targeting the product Red Hat Decision Manager 7.1.

  • developers evaluating open source rules and events tooling
  • architects tasked with evaluating technology for potential use in organization
  • business or information analysts interested in exploring rule design tooling

2. Rules, events and processes

[Updates in progress on this section]

Before you get started with products in this technology space, a bit of a background on what rules, events and processes are about in relation to Red Hat offerings is in order. Here you will find a nice walk through the concepts as they can be applied using Red Hat business rules and process automation products, all in around 15 minutes.



3. Get the products

The first thing one needs is the product, so with Red Hat Decision Manager this means we want the archives and a JBoss EAP server. We have two options depending on the what you are looking for:
  1. Red Hat Customer Portal - hosts all available versions of JBoss EAP & Red Hat Decision Manager that you can access via your credentials when you have a valid subscription for JBoss  products. 
  2. Developers Product Pages - hosts selected major versions of Red Hat Decision Manager and you can get selected versions of JBoss EAP without a full subscription. You only need a valid developers account and agree to a $0 developer subscription before gaining access to the available versions for download. 
Below you will find demo projects that are based on various versions of the products, some of which you can preview without a subscription by downloading at jboss.org. Please check the revisions available to pull a tagged version of a project that uses product versions you want to try out.

There is an extensive collection of example demo projects that range from a simple clean Red Hat Decision Manager installation to more complex multi-product integration scenarios and everything in between.

Each demo project has the same consistent template, the same user login unless specified in the documentation and install in exactly the same way as shown in the Quick Tour videos above. All these projects install on the OpenShift Container Platform, provided as optional installation, use your own, or make use of other options like the Red Hat Container Development Kit (CDK).

Workshop in a can
Looking for an easy way to promote, present or demonstrate how easy it is to get started with JBoss BRMS product?

Look no further as we have pulled together this workshop so that you can construct an evening, half day or full day session of learning around JBoss BRMS.

You can setup this workshop and run it at any event as it can be constructed to take from a half to full day to complete. Think of the following possibilities for this workshop:
  • local Java User Group (JUG)
  • local JBoss User Group (JBug)
  • local tech meetup
  • work interest group
  • after hours meetup at work
  • submit it to a conference (yes you can use this!)
The workshop outlines how to build an online retail shopping cart project that uses all the rules and events that JBoss BRMS offers. Not only that, you get to build them all hands on with the various web based tooling that the product offers.
