Oracle Cloud Applications Integration – Part 1: Connecting and Extending Oracle Cloud Applications

Oracle Cloud Applications Integration (OCAI) is a set of APIs and services that provides integration capabilities to Oracle Cloud Applications.

OCAI enables developers to create connectors and adapters that connect their applications to external systems and services.

This article describes the architecture of Oracle Cloud Applications Integration, explains how you can use OCAI tools and utilities, and how you can extend Oracle Cloud Applications with integration services. Read ahead.

What is Oracle Cloud Applications Integration?

Oracle Cloud Applications Integration (OCAI) is an integration framework that allows you to connect and extend Oracle Cloud Applications. OCAI allows you to integrate Oracle Cloud Applications with on-premises systems, third-party data sources, and cloud services.

You don’t need to have any development experience to leverage OCAI. You can also use OCAI to integrate with Oracle Cloud Infrastructure. 

When you integrate with Oracle Cloud Infrastructure, you can provide additional services to your users without having to provision, configure, and manage those services.

OCAI Connector Architecture

OCAI Connector Architecture is based on open standards, with each connector following a plug-and-play architecture. The OCAI Connector Architecture supports publishing and subscribing to events. 

Developers can use the OCAI API to build custom connectors and extend Oracle Cloud Applications with new capabilities.

The OCAI API follows an event-driven model that uses an asynchronous push mechanism for notifications, allowing high scalability and consistency across all connected systems.

OCAI Adapter Framework

The Oracle Cloud Applications Integration Adapter Framework is a set of Java classes that help you create adapters for Oracle Cloud Applications.

The OCAI Connector Architecture provides an event-driven runtime environment for your adapters. It gives them access to the application’s data and enables them to interact with each other within an application.

This removes any worries about context switching or concurrency issues because they run the same process as other adapters on behalf of the same user session.

OCAI Tools and Utilities

OCAI tools and utilities are available in the Oracle Cloud Applications Integration (OCAI) GitHub repository. 

These tools include:

  • OCAI CLI: Command-line interface for automating cloud application integration processes using OCAI.
  • OCAI PowerShell Cmdlets: PowerShell cmdlets for automating cloud application integration processes using OCAI.
  • REST API: REST API can be used to programmatically manipulate your data sources, connectors, flow rules, and other resources. You can manage your system configuration settings through an interactive web interface or programmatically via a REST API call.

Extending Oracle Cloud Applications with Integration Services

Oracle Cloud Applications Integration (OCAI) is a platform-independent solution that can be used to connect and extend Oracle Cloud Applications. 

It provides:

  • Connectivity to on-premises sources, third-party data sources, and cloud services.
  • Integration between Oracle Cloud Applications and existing systems and processes.
  • Automated business processes using pre-built integration flows or custom code in any language supported by OCAI (Java, Python, or Node.js).

OCAI also supports the development of custom connectors for integrating with non-Oracle products if needed.

Creating Connections to External Systems and Services

You can create connections to external systems and services in Oracle Cloud Applications Integration. 

Besides, you can use these connections to integrate the data from your existing applications with the data in Oracle Cloud Applications.

  • Create a connection to an external system: You can establish a seamless connection between one or more Oracle Cloud Applications entities and an external system.
  • Create a connection to an external service: You can connect one or more Oracle Cloud Applications entities and an external service.
  • Define properties for your new connection: It lets you specify properties, such as authentication details, location preferences, security levels, etc.

Benefits of Integration

Integration is a crucial aspect of your organizational operations, as it provides numerous benefits that can significantly transform how your business operates. Through integration, you can seamlessly connect Oracle Cloud Applications with other systems, improving productivity, data accuracy, and reducing costs.

By eliminating manual data entry, integration can save you time and money while increasing efficiency. This is simply because inputting data manually is often time-consuming and prone to errors, which can lead to costly mistakes. Integration can also streamline processes by automating tasks that would otherwise require manual intervention, freeing up your employees to focus on more critical tasks.

Moreover, integration allows real-time data sharing, significantly improving decision-making and customer service. For instance, integrating your Oracle ERP Cloud with a reliable Salesforce system can enable real-time data sharing between the two systems. This can help your sales team access the latest information about customer orders, invoices, and payments. As a result, you will have improved decision-making and customer service.

Apart from these benefits, integration can provide you with a competitive edge. By integrating their systems, organizations can gain a comprehensive view of their operations, which can help them identify areas for improvement and make informed decisions. Therefore, you can stay ahead of your competitors thanks to the acquired agility and flexibility needed to adapt to changing business environments.

Integration Challenges

Integration can indeed be a challenging process, especially when working with complex systems and multiple applications. However, it is also a crucial process as it ensures that all systems work seamlessly together.

One of the common integration challenges is data mapping. Data mapping involves matching data elements from one system to another. It can be difficult when there are differences in the integrated systems’ data structures. Another challenge is data transformation, which involves converting data from one format to another. This can also be a complex process and requires you to understand the data structures of both systems being integrated thoroughly.

Error handling is another critical aspect of integration. Thus, you must have a plan to handle errors that may occur during integration. The plan should outline:

  • Which steps are to be taken when an error occurs?
  • Who is responsible for handling the error?
  • How will the error be communicated to relevant stakeholders?

To overcome these integration challenges, you should develop a comprehensive integration strategy. For this, you can get along with experienced integration experts, as they can provide valuable insights and guidance throughout the integration process.


Overall, successful OCAI integration can be the defining factor in your organization’s success. However, there can be many challenges in setting up Oracle Cloud Applications Integration from scratch. So, you should contact experienced integrations to obtain the required help for success.
