Steps to Reproduce
Create a Strategy Rule and exeucte a Test Run.
Root Cause
A software use or operation error. When installing Pega Marketing the Dynamic System Setting of prconfig/initservices/dnode/default needs to be set to true. After this setting has been applied, all the server nodes need to be restarted so the com.pega.dsm.dnode.api.DNodeServiceListener can be instantiated. This is required to run a Strategy.
Resolution
Apply Dynamic System Setting of prconfig/initservices/dnode/default to true and restart all the server nodes.
