Solution Diagram

The technical aspects involved in Oracle Utilities Customer Cloud Service Integration to Oracle Utilities Work and Asset Cloud Service for Service Requests are:

• The integration layer is made up of integration processes deployed on Oracle Integration Cloud.

• It uses REST APIs to facilitate communication between the two applications.

• In the Oracle Utilities Customer Cloud Service initiated processes, outbound messages are sent and Oracle Utilities Work and Asset Cloud Service uses REST API to receive the messages.

The integration patterns used in this solution are:

• Synchronous

• One-way Asynchronous

Synchronous

The synchronous integration process:

1. Receives request message from the source application.

2. Transforms the message from source format to the target format. Lookups are used for data translations.

3. Invokes the target application.

4. Transforms the message (after invoking the target application) from the target format back to the source format. It sends back an acknowledgment/synchronous response.

5. In case of any error, the global fault handler catches them and sends the transformed error message to the source application.

6. An optional email notification is sent to the respective users as configured.

One-way Asynchronous

The one-way asynchronous integration process:

1. Receives request message from the source application.

2. Transforms message from the source to the target format. Lookups are used for data translations.

3. Invokes target application to send the request message.

4. In case of any error, the global fault handler catches them.

5. The error instance can be re-submitted from Oracle Integration Cloud. Refer to the Error Handling section in Chapter 6: Configuring Lookups, Error Handling, and Email Notifications for more details.
