Oracle Integration Cloud (OIC) is Oracle’s cloud-based integration platform used to connect SaaS applications, on-premises systems, databases, APIs, and business processes.

Oracle introduced Oracle Integration 3 (Gen 3) as the next generation of OIC with an improved user experience, project-based development, enhanced monitoring, AI-assisted capabilities, better scalability, and simplified administration.

In this blog, we will compare OIC Gen 2 and Gen 3, understand their differences, and explore the advantages of upgrading to Gen 3.

OIC Gen 2 Overview:

Embedded SFTP	Limited	500 GB Embedded SFTP
For-Each Processing	5000 records limitation	Unlimited processing
Scalability	Standard	Higher scalability
Resource Organization	Separate artifacts	Projects for grouping assets

Projects – The Biggest Change in Gen3:

• One of the most significant enhancements in Gen 3 is the introduction of Projects. 
• In Gen 2, integrations, connections, lookups, and libraries are managed separately. 
• In Gen 3, all related artifacts can be grouped into a single project. 

1. Project Structure in Gen 3

A project can contain: 

• Integrations 
• Connections 
• Lookups 
• Libraries 
• Deployments 

Benefits

• Better organization 
• Easier migration 
• Team collaboration 
• Simplified deployment 

2. Improved Observability

Gen 3 introduces Observability, which provides a centralized monitoring experience. 

• Benefits 
• Runtime monitoring 
• Schedule monitoring 
• Audit tracking 
• Error visibility 
• Faster troubleshooting 

This makes support and production monitoring significantly easier compared to Gen2. 

3. Enhanced Deployment Experience

In Gen 2: 

• Integrations are deployed individually. 

In Gen 3: 

• Entire projects can be deployed together. 
• Related artifacts move as a unit. 

Benefits: 

• Reduced deployment effort 
• Better release management 
• Easier promotion across environments 

4. User Interface Comparison

Gen 2 UI Characteristics

• Menu-driven navigation 
• Separate modules 
• Traditional layout 

Gen 3 UI Characteristics

• Modern dashboard 
• Project-oriented navigation 
• Better visibility 
• Simplified design 

5. Scalability Improvements

Gen 3 offers better scalability compared to Gen 2.

Examples include: 

• Increased active integration limits 
• Better performance 
• Improved infrastructure handling 
• Enhanced cloud-native architecture 

Gen 3 is designed to support larger enterprise workloads with better operational efficiency. 

6. Security and Administration Enhancements

Gen 3 introduces improvements in: 

• OIC Gen3 integrates with Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) 
• Role-based access control 
• Governance 
• Instance management 
• OCI-based administration 

Oracle also manages several infrastructure responsibilities that previously required administrator intervention.

Migration from Gen 2 to Gen 3

Oracle provides an upgrade path from Gen 2 to Gen 3 without additional licensing cost. 

Before upgrading: 

• Review Visual Builder applications 
• Validate integrations 
• Verify custom endpoints 
• Review authentication methods 
• Test adapters and connections 

After upgrading: 

• Update IAM policies 
• Revalidate connections 
• Perform end-to-end testing 

Advantages of Upgrading to Gen 3 

The following advantages highlight why upgrading from OIC Gen 2 to Gen 3 can improve integration development, scalability, monitoring, and overall operational efficiency.

• Better Developer Experience 
• Modern UI 
• Faster navigation 
• Project organization 
• Better Operations 
• Enhanced monitoring 
• Observability dashboards 
• Better Governance 
• Improved access control 
• Simplified administration 
• Better Scalability 
• Higher processing limits 
• Improved performance 
• Future Readiness 
• AI-powered enhancements 
• Oracle’s strategic platform direction 

Conclusion 

Oracle Integration 3 is more than just a UI upgrade. It introduces a project-centric development model, advanced observability, simplified deployments, improved scalability, and enhanced governance capabilities. 

Organizations currently using OIC Gen 2 can benefit from improved developer productivity, easier monitoring, and better lifecycle management by moving to Gen 3. As Oracle continues investing in Integration 3, it becomes the preferred platform for future integration development and enterprise automation initiatives
