What is the purpose of plan.xml and how PRPC use it at runtime
When installing Pega7 (7.1.8) on WebLogic (based on 7.1.8 installation guidance) it's talk about creating a plan.xml and configuring two schemas (Rules & Data) in there instead of giving it under prConfig.xml. Doing that.. basically PRPC able to have one data source from WebLogic and at the run-time it recognized the two sachems out from Plan.xml.
Can anyone help me on understanding how PRPC do this functionality?
