To create a data server for each of the related logical schemas:
Launch Oracle Data Integrator Studio, then select the Physical Architecture tab.
Enter a name and connection information on the Definition tab, then the JDBC driver and URL. Then, click Save.
Select the value for the schema and work schema from the drop down list.
Do not type in the value as the schema is case sensitive in some environments.
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.
