To create a data server for each of the related logical schemas:
Launch Oracle Data Integrator Topology Manager, then select the Physical Architecture tab.
A technology item for PeopleSoft does not explicitly exist in the list of items. Select the database technology used for the PeopleSoft instance.
Ensure that you have created all data servers and physical schemas listed in Creating Data Servers and Physical Schemas. Then, create contexts. See Creating Contexts.
