Solution Diagram
The technical aspects involved in Oracle Utilities Work and Asset Cloud Service Integration to Oracle Field Service are:
• An integration between Oracle Utilities Work and Asset Cloud Service and Oracle Field Service.
• The integration layer is made up of integration processes deployed on Oracle Integration Cloud.
• It uses web services and REST APIs to facilitate communication between the two applications.
• In the Oracle Utilities Work and Asset Cloud Service initiated processes, outbound messages are sent and Oracle Field Service uses REST API to receive the messages.
• In the Oracle Field Service initiated processes, events are triggered and Oracle Utilities Work and Asset Cloud Service uses inbound web services (IWS) to receive the messages.
The integration patterns used in this solution are:
Synchronous
The synchronous integration process:
1. Receives request message from Oracle Utilities Work and Asset Cloud Service.
2. Transforms the message from Oracle Utilities Work and Asset Cloud Service format to the target format. Lookups are used for data translations.
3. Invokes Oracle Field Service.
4. Transforms the message (after invoking Oracle Field Service) from the Oracle Field Service 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 Oracle Utilities Work and Asset Cloud Service.
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 Oracle Field Service.
2. Transforms message from the source to the Oracle Utilities Work and Asset Cloud Service 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 Configuring Lookups, Error Handling, and Email Notifications for more details.
