Basic Oracle Integration Cloud Interview Questions

1. What is Oracle Integration Cloud (OIC)?

Answer: Oracle Integration Cloud (OIC) is a cloud-based integration platform that allows businesses to connect applications, automate workflows, and enable seamless communication between SaaS and on-premises applications. It includes application integration, process automation, visual application development, and API management.

2. What are the key components of Oracle Integration Cloud?

Answer: The main components of OIC are:

Integration (OIC) – Enables seamless connectivity between applications.

Process Automation – Automates business processes using workflows.

Visual Builder – A low-code platform for developing web and mobile applications.

B2B Integration – Supports EDI-based business-to-business communications.

API Management – Manages API lifecycles for secure integrations.

3. What are prebuilt adapters in OIC?

Answer: Prebuilt adapters are predefined integration components that simplify connectivity between applications like Oracle ERP, Salesforce, Workday, SAP, and third-party applications.

4. What protocols does Oracle Integration Cloud support?

Answer: OIC supports various protocols, including REST, SOAP, FTP, JMS, and database connections, ensuring seamless application integration.

5. How does Oracle Integration Cloud handle errors in integrations?

Answer: OIC provides robust error-handling features like:

• Fault Policies – Defines automated error-handling rules.
• Tracing & Monitoring – Enables tracking of failed messages.
• Integration Resubmission – Allows users to manually or automatically retry failed transactions.

6. What is the role of Lookup in OIC?

Answer: Lookups in OIC act as mapping tables to facilitate value translations between different applications in an integration flow. They help in managing data transformations between disparate systems.

7. How do you secure integrations in Oracle Integration Cloud?

Answer: OIC ensures security using:

• OAuth 2.0 and JWT tokens for authentication
• Role-based access control (RBAC) for user permissions
• Secure credential storage for API authentication
• IP whitelisting and data encryption for secure data transfer

8. What is a Scheduled Integration in OIC?

Answer: A Scheduled Integration executes at predefined intervals (hourly, daily, weekly, etc.) instead of being triggered by an event. It is commonly used for batch data processing and file-based integrations.

9. What is the difference between File-Based and App-Driven Integrations?

Answer:

File-Based Integration: Involves exchanging bulk data via FTP/SFTP (e.g., importing/exporting data from Oracle ERP).

App-Driven Integration: Real-time or event-driven integrations triggered by applications (e.g., new customer data sync between Salesforce and Oracle).

10. How does OIC support real-time integrations?

Answer: OIC supports real-time integrations through event-based triggers, webhooks, REST/SOAP API calls, and streaming services that enable immediate data synchronization between systems.

Scenario-Based Oracle Integration Cloud Interview Questions

11. How do you migrate integrations between OIC environments (Dev, Test, Prod)?

Answer:

• Export the integration from the source environment as an IAR (Integration Archive) file.
• Import it into the target environment.
• Update connection details and endpoint configurations as needed.
• Test the integration before deployment.

12. Can you modify an active integration without downtime?

Answer: No, an active integration cannot be modified directly. You must:

• Clone the existing integration.
• Apply changes and test in a lower environment.
• Deactivate the old version and deploy the updated integration.

13. What are business identifiers in OIC, and why are they important?

Answer: Business identifiers are key fields that help track transactions within an integration flow. They enhance monitoring and troubleshooting by allowing users to search and filter instances based on business-relevant attributes.

14. How would you handle duplicate message processing in an integration?

Answer: OIC provides de-duplication policies that prevent duplicate messages by checking unique identifiers before processing.

15. How can you improve integration performance in Oracle Integration Cloud?

Answer: Best practices include:

• Using asynchronous processing where possible
• Optimizing data mappings and transformations
• Leveraging bulk operations instead of individual API calls
• Using caching mechanisms to minimize redundant processing

Expert-Level Oracle Integration Cloud Interview Questions

16. How does Oracle Integration Cloud support hybrid integrations?

Answer: OIC connects both cloud and on-premises applications through:

Connectivity Agents – Enables secure on-premises system integration.

VPN and Private Link – Establishes secure cloud-to-data center connections.

Hybrid Event-Driven Architecture – Supports real-time event processing across environments.

17. What is the Visual Builder in OIC, and how is it used?

Answer: Visual Builder (VB) is a low-code development tool within OIC that allows users to create web and mobile applications quickly. It integrates seamlessly with OIC services, making it easy to build frontend interfaces for backend APIs.

18. What is the role of API Gateway in OIC?

Answer: The API Gateway manages, secures, and monitors API interactions in Oracle Integration Cloud. It helps with:

• Authentication & access control
• Rate limiting & throttling
• Logging & analytics

19. What are the different monitoring options in OIC?

Answer:

Activity Stream – Provides real-time logs of integration executions.

Dashboard Metrics – Displays key performance indicators (KPIs).

Integration Insight – Offers end-to-end visibility into business transactions.

Audit Logs – Tracks user actions and changes.

20. How does OIC handle long-running processes?

Answer: OIC uses Process Automation (BPM) to manage long-running processes through:
