Essential Oracle Fusion Technical Questions for IT Job Success in 2025
General Concepts
1. What are the key components of Oracle Fusion Technical architecture?
A. Oracle Fusion Technical + OIC Online Training architecture consists of Oracle WebLogic Server, Oracle Database, ADF (Application Development Framework), BI Publisher, SOA (Service-Oriented Architecture), and Web Services (REST & SOAP).
2. What is the role of Oracle ADF in Fusion Applications?
A. Oracle Application Development Framework (ADF) is used to build UI components in Fusion Applications, providing reusable components, MVC (Model-View-Controller) architecture, and declarative development.
Data Handling & Integration
3. How do you migrate data into Oracle Fusion Applications?
A. Using File-Based Data Import (FBDI), Application Development Framework Desktop Integration (ADFDI), HCM Data Loader (HDL) for HCM modules, and SOAP/REST APIs.
4. What is FBDI, and how does it work?
A. FBDI (File-Based Data Import) is a bulk data loading tool that allows CSV file uploads to Oracle Fusion using predefined templates and staged tables before final import.
5. What is HDL, and when is it used?
A. HCM Data Loader (HDL) is used for loading HCM-related data like employee records, payroll, and job roles, supporting bulk data transfers.
6. How do you develop custom integrations in Oracle Fusion?
A. Custom integrations are built using Oracle Integration Cloud (OIC), SOA Suite, REST/SOAP Web Services, BIP Reports, and OTBI extracts.
Reporting & BI
7. What are the different reporting tools available in Oracle Fusion?
- Oracle Transactional Business Intelligence (OTBI)
- BI Publisher (BIP)
- Smart View for Excel
- Financial Reporting Studio (FRS)
8. How do you schedule reports in Oracle Fusion?
A. Reports can be scheduled using the BI Publisher scheduler, ESS Jobs (Enterprise Scheduler Services), and OTBI scheduled extracts.
9. What is the difference between OTBI and BI Publisher?
A. OTBI is used for real-time ad-hoc reporting, while BI Publisher is used for pixel-perfect, batch, and scheduled reporting with advanced formatting.
Security & Customization
10. How does Oracle Fusion handle security and role-based access control?
A. Oracle Fusion uses Role-Based Access Control (RBAC), where Job Roles, Duty Roles, and Data Access Policies are assigned to users via Oracle Identity Cloud Service (IDCS).
11. How do you create a new security role in Oracle Fusion?
A. Navigate to Security Console, define a new role, assign privileges and data security policies, and assign the role to users.
12. How do you customize Oracle Fusion UI using Page Composer?
A. Page Composer allows customization of Oracle Fusion UI by modifying fields, layouts, and components without altering the core application.
13. What is Oracle Sandbox, and why is it used?
A. Oracle Sandbox provides a safe environment to test and apply UI customizations before deploying them in a live system.
Workflows & Business Processes
14. How do you configure approval workflows in Oracle Fusion?
A. Using BPM (Business Process Management) Worklist to define workflow rules, conditions, and escalations.
15. What is Oracle BPM, and how does it work in Fusion Applications?
A. Oracle BPM (Business Process Management) automates business workflows and approvals, ensuring process standardization across applications.
Technical Development & Extensions
16. How do you develop extensions in Oracle Fusion?
A. Using Oracle Visual Builder (VB), Application Composer, ADF Personalization, and Groovy scripting for logic customization.
17. What is the purpose of REST and SOAP APIs in Oracle Fusion?
A. REST and SOAP APIs allow external applications to fetch, update, and delete data in Oracle Fusion Cloud using standard web service protocols.
18. How do you troubleshoot performance issues in Oracle Fusion?
A. Performance tuning involves monitoring ADF logs, WebLogic performance metrics, SQL tuning, and optimizing BIP reports.
Advanced Topics & Best Practices
19. What are the best practices for handling data migration in Oracle Fusion?
A. Use incremental data loads, validate data before migration, leverage FBDI/HDL templates, and test in a staging environment before deployment.
20.. What are Oracle Fusion Sandbox and Application Composer used for?
A. Sandbox is for testing configurations without affecting live users.
Application Composer is used to create new fields, modify objects, and develop lightweight extensions.
