In Oracle Integration Cloud (OIC), error handling is an essential aspect of designing and implementing integrations. It allows you to manage exceptions and unexpected situations that may occur during the integration process. Proper error handling ensures that your integrations continue to function smoothly even when errors occur and helps in identifying and resolving issues efficiently.

There are several ways to handle errors in Oracle Integration Cloud. Some common practices include:

1. Error Hospital: OIC provides an “Error Hospital” feature, where errors encountered during integration executions are automatically routed to the Error Hospital. You can access the Error Hospital from the Monitoring dashboard. It allows you to view the error details, retry the failed instance, or manually correct and resubmit the failed data.

2. Fault Policies: You can use fault policies to define specific actions when an error occurs during integration execution. These fault policies can be applied at various levels, such as integration, orchestration, or individual actions. You can configure fault policies to perform actions like retrying the integration, raising notifications, logging errors, or executing alternate actions based on the error type.

3. Catching Errors in Orchestrations: When you design an integration using an orchestration, you can include “Catch” activities to handle specific types of errors. The catch activity allows you to define the actions to be taken when an error of a specific type occurs during the orchestration’s execution.

4. Error Notification: OIC allows you to configure email notifications when errors occur during integration executions. You can set up notifications to be sent to specified recipients or distribution lists, helping the support team to be aware of issues quickly.

5. Custom Error Handling: You can implement custom error handling logic within your integration flows using integration flows, JavaScript code, or other relevant technologies. Custom error handling gives you more control over how errors are managed and allows you to take specific actions based on the integration’s requirements.

6. Integration Resubmission: In the Monitoring dashboard, you can manually resubmit failed integrations after addressing the errors. This is helpful when you want to rerun the integration after resolving the issue that caused the failure.

When designing your integrations, consider implementing a comprehensive error handling strategy that includes a combination of the above techniques. This ensures that your integrations are robust, reliable, and capable of handling various error scenarios that may arise during runtime.
