Chapter 5. Known issues in Red Hat Decision Manager 7.7.0

This section lists known issues with Red Hat Decision Manager 7.7.

5.1. Business Central

In a high-availability deployment of Business Central, deploying a service to a KIE Server using Business Central intermittently fails [RHPAM-2830]

Issue: In a high-availability deployment of Business Central, Sometimes the service is not deployed to a KIE Server when you use the Business Central user interface in a high-availability deployment.

Workaround: There is no workaround in an on-premise deployment using the Red Hat JBoss EAP. Do not use an on-premises high-availability deployment of Business Central to deploy services to KIE Servers.

In a deployment on Red Hat OpenShift Container Platform, the issue is resolved starting in Red Hat Decision Manager version 7.7.1. When you deploy a high-availability authoring environment on Red Hat OpenShift Container Platform in Red Hat Decision Manager version 7.7.0, you must enable the OpenShiftStartupStrategy setting. For instructions about enabling this setting, see Enabling the OpenShiftStartupStrategy setting to connect additional KIE Servers to Business Central in the Deploying a Red Hat Decision Manager authoring or managed server environment on Red Hat OpenShift Container Platform document. You must complete this procedure even if you do not connect any additional KIE Servers to Business Central.
