Creating a Phase Activity
In two-layer BPM, a phase is a level-1 activity in the BPEL process. It complements the existing higher-level Oracle Business Rules and human task BPEL activities.
You add a phase activity to a process declaratively in Oracle BPEL Designer by dragging and dropping it from the Oracle Extensions section of the Components window to the process model. Figure 55-2 provides details.

Note:
The reference WSDL (layer 2 or called references) must have the same abstract WSDL as that for the phase reference that gets automatically created.
