Introduction

In today’s cloud-based business world, integrations are the backbone of seamless communication across systems. For businesses leveraging Oracle Fusion Applications—whether it’s Finance, HR, Supply Chain, or other key business functions—ensuring that these systems are connected with external services is critical. Event-based integrations are essential for triggering real-time actions based on key business events, like a new purchase order or a status change in a sales pipeline.

Oracle Integration 3 (OIC 3) has made major strides in simplifying the management and troubleshooting of these event-based integrations, especially with Oracle Fusion Applications. The platform enhances visibility into integration issues, reduces downtime, and offers improved error management features, making it easier for administrators to keep everything running smoothly.

In this blog, we’ll dive into how OIC 3 enhances event-based integrations with Oracle Fusion Applications, providing you with tools to diagnose, fix, and optimize integrations—ensuring that your Fusion-driven processes stay efficient and error-free.

What’s Event-Based Integration Anyway?

In the context of Oracle Fusion Applications, event-based integrations allow external systems to automatically respond to specific business events, such as updates to records, changes in order status, or new employee onboarding. For example, when a new purchase order is created in Oracle Fusion, an event-based integration might trigger an external system to update inventory or notify a supplier.

The beauty of event-based integrations is that they work asynchronously, meaning the event is processed without waiting for a response, allowing other operations to continue without delay.

Oracle Integration 3 (OIC 3) builds on this concept, introducing advanced tools for managing these integrations, improving visibility, and tracking issues quickly.

What’s New in OIC 3 for Event-Based Oracle Fusion Integrations?

Oracle Integration 3 introduces several powerful features that streamline the management of event-based integrations in Oracle Fusion Applications. These features allow administrators to easily monitor, troubleshoot, and ensure the reliability of integrations with Fusion systems:

🔍 Smarter Error Tracking

Gone are the days of cryptic error codes and frustrating guesswork. With OIC 3, you get detailed, descriptive error messages and context for each failure. This allows you to pinpoint exactly where things went wrong, whether it’s a misconfiguration or a problem in the downstream system.

📊 Observability Page

OIC 3 includes a real-time Observability page that gives a snapshot of the health and performance of event-based integrations. It’s a central place to monitor integration activities, view failed events, and track retries—all in one easy-to-read dashboard.

To access the Fusion Applications observability features, navigate via the navigation pane: Click Observability, then select Fusion Applications. This page provides an up-to-the-minute view of integration statuses, failure rates, and more, making it easier to track the status of Oracle Fusion event-based integrations.

🧾 Detailed Logs and Metadata

Every failed event now comes with detailed logs and metadata, showing exactly where the failure occurred, why it happened, and what you can do to fix it. This is especially important in environments with high volumes of integrations, where pinpointing issues quickly is key to preventing business disruption.

🎯 On-Demand Retry Capability

OIC 3 allows administrators to manually retry failed events. Once the root cause of a failure is resolved, event retries can be triggered on-demand—allowing you to quickly reprocess events without needing to reconfigure the entire integration. This gives you full control over how to handle integration failures in Oracle Fusion Applications.

Real-Life Example: Callback URL Problem

Let’s explore a common issue you might face when managing event-based integrations in Oracle Fusion—an incorrect callback URL.

Callback URLs are used to notify external systems that an event has occurred. When this URL is misconfigured—whether due to a typo or an incorrect endpoint—Oracle Fusion will attempt to call the integration but fail.

Here’s how Oracle Integration 3 (OIC 3) handles the issue:

1. The Failure is Logged

When the callback URL is incorrect (e.g., it points to a non-existent endpoint or there’s a network issue), Oracle Fusion still tries to send the event. In such cases, Fusion will retry the call up to 10 times per event subscription.

For high-volume integrations (e.g., 40,000 events per day), this could lead to a huge number of failed calls, flooding your logs and causing potential API bottlenecks. If 10 retry attempts per event fail, it’s logged and visible on the Observability page in OIC 3.

2. You Get a Heads-Up on the Observability Page

The failure will be shown clearly on the Observability page in Oracle Integration 3. You’ll see information about the event name, error code, and the number of retry attempts. To view this, simply navigate to Observability from the navigation pane and select Fusion Applications.

This allows you to see all failed events in Fusion-based integrations, their status, and error details, giving you the visibility needed to address the problem.

3. You Get Detailed Error Info

Here’s an example of what you might see in the error log:

• Message: Callback URL is unreachable

• Event: Purchase Order Created

• Time: 12:05 PM

• Error Code: 404 Not Found

4. You Fix the URL

Once you identify that the callback URL is the issue, you can proceed to fix it in the integration configuration. There are several common ways incorrect URLs creep into production environments:

• Leftover test integrations: Sometimes, test integrations from pre-production environments accidentally slip into production, still pointing to non-existent or temporary URLs.

• Versioning mistakes: When updating an integration (e.g., moving from version 1.0 to 2.0), if event subscriptions from older versions are not removed, you might end up with duplicate integrations trying to handle the same event. If one version is deactivated without removing the subscription in Fusion, you can run into failures.

To avoid this, always ensure that only the active version of your integration is subscribed to events and that old, unused test integrations are removed from production.

5. You Retry the Integration On-Demand

Once the callback URL is fixed, you can manually retry the event via the Observability page in OIC 3. This allows you to reprocess the event without reconfiguring everything.

6. Success!

After the event is retried successfully, the event status updates to “Succeeded” in the Observability dashboard, showing that the issue has been resolved.

Side-by-Side: OIC 2 vs. OIC 3

Here’s a comparison of how Oracle Integration 2 (OIC 2) and OIC 3 stack up when managing event-based integrations in Oracle Fusion Applications:

As you can see, OIC 3 introduces many improvements that make managing Fusion-based event integrations far more user-friendly and efficient.

Wrapping It All Up

Oracle Integration 3 has greatly enhanced how Oracle Fusion Applications integrate with external systems. With improved error tracking, real-time monitoring, and manual retry capabilities, troubleshooting event-based integrations has never been easier.

By leveraging these advanced tools, Oracle Fusion administrators can maintain reliable integrations, quickly resolve issues like misconfigured URLs, and ensure that their systems run without unnecessary downtime. If you’re still on OIC 2, it might be time to consider upgrading to take advantage of these powerful new features.
