NodeType nodes are set as 'Untyped' on startup



The -DNodeType is applied to the JVM argument to classify a Pega node within the cluster. 
During the startup, the NodeType value is ignored and error displays. As a result, the Node type is set to 'Untyped'.

Error Messages

Error in the PegaRULES.log file

(internal.NodeClassificationImpl) ERROR - Ignoring Invalid NodeType passed: ADM
(internal.NodeClassificationImpl) ERROR - Ignoring Invalid NodeType passed: PegaMKTEmail
(internal.NodeClassificationImpl) ERROR - Provided NodeTypes: ADM,PegaMKTEmail is not Valid. Hence turning off NodeClassification

Steps to Reproduce

Pass the -DNodeType JVM argument with Pega standard values such as, Search, Background, Custom1, etc.

Root Cause

The -DNodeType argument was passed twice to the whole argument set. Because of this duplicate entry, the later values are ignored and the classification led to the error.


Retain only the -DNodeType argument. If multiple values must be set, use a  comma separated format as below:
