In Oracle Integration Cloud (OIC), there is a default error handling mechanism that handles errors and exceptions that occur during the execution of integration flows. This default error handling is designed to provide a basic level of error handling and logging for your integrations. Here’s how it works:

1. Error Handling at the Integration Level:
   
   1. At the integration level, you can define a basic set of error handling actions that apply to the entire integration flow.
   2. This includes actions such as logging errors, sending notifications, and specifying retry behavior.
2. Error Notification:
   
   1. OIC has a built-in error notification mechanism that can send email notifications to designated recipients when errors occur in an integration.
   2. You can configure email notifications to be sent to specific users or groups, ensuring that relevant parties are alerted when an error occurs.
3. Error Logging:
   
   1. OIC provides built-in logging capabilities that capture error details, including fault messages, error codes, and error descriptions.
   2. These logs are accessible from the OIC console and can be used for troubleshooting and auditing purposes.
4. Retry Mechanism:
   
   1. By default, OIC includes a basic retry mechanism that can be configured to retry integration activities in case of transient errors.
   2. You can specify the number of retries and the retry interval.
5. Fault Policies:
   
   1. OIC allows you to define fault policies at the integration level, which specify how to handle specific fault types or fault codes.
   2. You can configure fault policies to trigger specific actions when particular errors occur.
6. Logging and Monitoring:
   
   1. OIC provides monitoring and logging capabilities that allow you to track the execution of your integrations, including error instances.
   2. You can access detailed logs and reports to analyze errors and their impact.

While the default error handling in OIC provides basic capabilities for handling and logging errors, it may not be sufficient for complex integration scenarios. In such cases, you can enhance error handling by using additional mechanisms such as:

• Custom Error Handling: Implement custom error handling logic within integration flows using Scope Fault Handlers, Throw New Fault actions, and Rethrow Fault actions to handle specific errors with more granularity.
• External Error Handling: Integrate with external error tracking and management systems or tools to centralize error handling and notifications.
• Business-Specific Error Handling: Customize error handling based on the specific requirements of your integration and the business processes it supports.
