Oracle Integration Cloud (OIC) is a comprehensive suite of integration services that enable you to connect your applications, automate processes, and create web APIs. One essential part of building robust integrations is the proper handling of faults or errors that can occur during the execution of an integration.

A fault in the context of OIC could mean any unexpected condition or error that occurs during execution, such as a failure to connect to an endpoint, a data mapping error, or an unexpected response from a service.

Here’s how you can handle faults in Oracle Integration Cloud:

1. Using Fault Policies

Oracle Integration Cloud allows you to define fault policies, which can catch specific faults and handle them in a predefined way. You can define actions that should be taken when a fault occurs, such as sending an alert, retrying the operation, or terminating the process.

2. Creating a Fault Handler

You can create a fault handler within the integration flow to catch and manage errors. Here’s a general guide to doing so:

1. Open the Integration: Open the integration where you want to add fault handling.

2. Add a Fault Handler: Inside the integration canvas, you can add a fault handler to a specific action or at the integration level.

3. Configure the Fault Handler: You can configure what types of errors the fault handler should catch. This could be based on error codes, error messages, or other criteria.

4. Define Actions: In the fault handler, you can define what actions should be taken when a fault is caught. This could include logging the error, sending a notification, or invoking another integration to handle the error.

5. Test the Integration: It’s always a good idea to test your fault handling to ensure it behaves as expected.

3. Using Built-in Functions

Oracle Integration Cloud provides built-in functions to handle faults. You can use these in expressions to help with fault handling, such as retrieving error messages or error codes.

4. Monitoring and Logging

Monitoring and logging play a crucial role in managing and understanding the faults in your integrations. Oracle Integration Cloud provides tools to monitor the execution of integrations, view logs, and analyze errors.
