Chapter 3. Available installation platforms
Every Red Hat Decision Manager release is certified on a variety of operating systems, JVMs, web browsers, and database combinations. Red Hat provides both production and development support for supported and tested configurations in both physical and virtual environments, according to your subscription agreement. See the following pages for information about supported configurations and version numbers:
Red Hat Decision Manager 7.8 is available for the following application platforms:
- Red Hat JBoss EAP
- Red Hat JBoss Web Server
- Red Hat OpenShift Container Platform
- Oracle WebLogic Server
- IBM WebSphere Application Server
3.1. Red Hat JBoss EAP 7.3
Red Hat JBoss Enterprise Application Platform (Red Hat JBoss EAP) 7.3 is a certified implementation of the Java Enterprise Edition 7 (Java EE 7) full and web profile specifications. Red Hat JBoss EAP provides preconfigured options for features such as high availability, clustering, messaging, and distributed caching. It also enables users to write, deploy, and run applications using the various APIs and services that Red Hat JBoss EAP provides.
You can install both Business Central and KIE Server in a single Red Hat JBoss EAP instance. However, in production environments you should install them in separate instances.
3.2. Red Hat JBoss Web Server
Red Hat JBoss Web Server is an enterprise-ready web server designed for medium and large applications, based on Tomcat. Red Hat JBoss Web Server provides organizations with a single deployment platform for Java Server Pages (JSP) and Java Servlet technologies, PHP, and CGI.
You can install KIE Server and the headless Decision Manager controller on Red Hat JBoss Web Server 5.3.1.
3.3. Red Hat OpenShift Container Platform
Red Hat OpenShift Container Platform (OpenShift) combines Docker and Kubernetes, and provides an API to manage these services. Openshift enables you to create and manage containers.
In this solution, components of Red Hat Decision Manager are deployed as separate OpenShift pods. You can scale each of the pods up and down individually, providing as few or as many containers as necessary for a particular component. You can use standard OpenShift methods to manage the pods and balance the load.
You can install both Business Central and KIE Server on OpenShift.
3.4. Oracle WebLogic Server
Oracle WebLogic Server is a Java EE application server that provides a standard set of APIs for creating distributed Java applications that can access a wide variety of services, such as databases, messaging services, and connections to external enterprise systems. Users access these applications using web browser clients or Java clients.
You can install KIE Server in an Oracle WebLogic Server instance and then use the headless Decision Manager controller and the REST API or the KIE Server Java Client API to interact with KIE Server. You can also use standalone Business Central to interact with KIE Server.
3.5. IBM WebSphere Application Server
IBM WebSphere Application Server is a flexible and secure web application server that hosts Java-based web applications and provides Java EE-certified run time environments. IBM WebSphere 9.0 supports Java SE 8 and is fully compliant with Java EE 7 since version 126.96.36.199.
You can install KIE Server in an IBM WebSphere Application Server instance and then use the headless Decision Manager controller to interact with KIE Server. You can also use standalone Business Central to interact with KIE Server.
3.6. Development options
Developers can develop assets in Red Hat Decision Manager. However, you can optionally integrate Red Hat CodeReady Studio with Red Hat Decision Manager to enable developers to write complex applications and leverage code auto-completion.
Red Hat CodeReady Studio is an integrated development environment (IDE) based on Eclipse. It integrates tooling and runtime components by combining Eclipse, Eclipse Tooling, and Red Hat JBoss EAP. Red Hat CodeReady Studio provides plug-ins with tools and interfaces for Red Hat Decision Manager. These plug-ins are based on the community version of these products. For this reason, the Red Hat Decision Manager plug-in is called the Drools plug-in.
