Oracle Integration Cloud (OIC) is a comprehensive solution for integration needs. It is a unified platform that includes a variety of different services, which work together to streamline business processes and data management. As of my last training cut-off in September 2021, the major components of Oracle Integration Cloud included:

1. Integration: The core service for creating integrations between different applications. It supports both application and data integration, and it allows users to automate and manage business processes.

2. Process: An environment for designing and managing business processes. It’s a low-code development platform that enables you to automate and optimize complex business processes, integrate with SaaS and on-premises applications, and create custom applications.

3. Visual Builder: A visual development environment that lets you create web and mobile applications. It’s a low-code development platform that can be used by both citizen and professional developers.

4. Insight: A tool for tracking business processes and metrics. It provides real-time visibility into business processes, helping organizations to understand their operations and make data-driven decisions.

5. Data Integration Platform Cloud (DIPC): A unified solution for real-time data integration, transformation, replication, and governance.

6. API Platform Cloud Service: This component helps to create, secure, and manage APIs, while also offering capabilities to monetize these APIs.

7. Integration Analytics: Helps to monitor, report, and alert on the activities and performance of your integrations, providing a real-time operational visibility.
