Abstract

Release notes for Red Hat JBoss BRMS 6.4.

Chapter 1. Introduction

About Red Hat JBoss BRMS

Red Hat JBoss BRMS is an open source decision management platform that combines Business Rules Management and Complex Event Processing. It automates business decisions and makes that logic available to the entire business.

Red Hat JBoss BRMS uses a centralized repository where all resources are stored. This ensures consistency, transparency, and the ability to audit across the business. Business users can modify business logic without requiring assistance from IT personnel.

The list of supported configurations for Red Hat JBoss BRMS is available at the Red Hat Customer Portal.

What Is New in Red Hat JBoss BRMS 6.4

Red Hat JBoss BRMS 6.4 is a minor release over the previous version 6.3. Noteworthy new features and improvements in this release are described below.

User Interface Improvements

The Realtime Decision Server now allows filtering the containers based on status and GAV (Maven Group ID, Artifact ID, and version). For more information, see the Containers and Unmanaged Intelligent Process Server Environment sections of the Red Hat JBoss BPM Suite 6.4 Development Guide.

The guided rule editor now enables you to use formulas for composite field constraints. When adding constraints to a pattern, the Multiple Field Constraint selection (All of (and) and Any of (or)) supports the use of formulas in addition to expressions. For more information, see the WHEN Conditions in Guided Rule Templates section of the Red Hat JBoss BRMS 6.4 User Guide.

Integration and Miscellaneous

The Google Chrome browser version 54.0.2840.7 is now supported.

Support for Russian and Traditional Chinese is no longer available for Red Hat JBoss BRMS 6.4.

Support for Java Development Kit (JDK) version 6 is no longer available for Red Hat JBoss BRMS 6.4.

Red Hat JBoss Developer Studio Integration Stack 10.0.0.GA supports Red Hat JBoss BRMS 6.4.

Red Hat JBoss Fuse 6.3 integration pack now includes and supports Red Hat JBoss BRMS 6.4.

The Update-04 for JBoss Operations Network (JON) 3.3 plugin is available for use with Red Hat JBoss BRMS 6.4.

Spring integration has been upgraded from Spring 3.x to 4.3.

KieScanner support is now available in Blueprint integration. For more information, see the Integration with Aries Blueprint chapter of the Red Hat JBoss BRMS 6.4 Admnistration and Configuration Guide.

Error messages while uploading spreadsheet as multi-bytes name have been improved. Asset names in error messages are now in a human-readable format and are easy to troubleshoot.

Chapter 2. Known Issues

These are the known issues for Red Hat JBoss BRMS 6.4:

When all next moves are not doable, optaplanner get stuck in step and if termination is not based on time, it cycles forever [RHBRMS-1726]

If the Business Resource Planner is in a state where all the entities are immovable, it gets stuck and only time based termination can terminate it. To workaround this issue, call the Solver.terminateEarly() method to break the cycle.

Use of "contains" operator does not add values from enumeration with quotes in Guided Rules etc. [RHBRMS-2577]

When using enumeration for a field in guided rules, guided decision tables, or guided decision templates, the resulting rule does not contain the selected value from the enumeration drop down within quotes ("") resulting in validation errors. There is currently no workaround for this issue.

Backward-incompatible change in ModifyCommand [RHBRMS-2703]

The JAXB marshalled form of org.drools.core.command.runtime.rule.ModifyCommand has changed and is backward incompatible. If you are creating an XML for marshalled command manually, you need to modify the attributes annotated by JAXB for marshalling in the XML. For more information, see the Migrating from 6.X to 6.4 section of the Red Hat JBoss BPM Suite 6.4 Migration Guide.
