1. Projects – The Biggest Change in Gen 3: 

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. 

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 Gen 2. 

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 Gen 3 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 

• 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
