Environment:
===========
TIBCO BusinessEvents 5.1.1
All Operating Systems

Symptoms:
=========
Failed to start InferenceAgent when a separate CacheAgent has been started before the InferenceAgent.

Cause:
======
Configuration error.

Resolution:
========
Update the CDD file and move the property be.engine.cluster.as.tuple.explicit  (value : true) from the  AgentClass (InferenceAgent) to the Cluster area
(CR BE-19866 exist to update the CDD file in next version(s))

Note: Catalog function Query.Util.startDynamicQuerySession() is not available in TIBCO BusinessEvents version 5.1.1, so it is not required to execute that catalog function in the startup RuleFunction of the InferenceAgent as mentioned in the manual (CR BE-19867 exists to update the manual).
