Oracle Application Development Framework (ADF) is the technology used to build the user interface and manage business logic for Fusion Applications. It allows developers to use reusable components, task flows, and managed beans. 4. What is ESS, and how is it used?
A:
ESS (Enterprise Scheduler Service) is a tool for scheduling and executing batch jobs, such as data imports, report generation, or updates. It helps automate routine tasks in Oracle Fusion.
5. Explain the FBDI process for data migration.
A:
FBDI (File-Based Data Import) is a tool for bulk data loading into Oracle Fusion. Steps include:
Download the FBDI template.
Populate it with data.
Upload the file in the Fusion application.
Monitor the ESS job for any errors.
6. What is OTBI different from BI Publisher?
A:
OTBI (Oracle Transactional Business Intelligence): used for prebuilt subject areas and ad hoc, real-time reporting.
BI Publisher: A more advanced tool for creating pixel-perfect reports and templates.
7. What are SOAP and REST APIs in Oracle Fusion?
A:
SOAP APIs: Used for robust, XML-based data exchange.
REST APIs: Lightweight and used for modern integrations with JSON.
8. Describe Oracle Integration Cloud (OIC) and explain its significance.
A:
Oracle Integration Cloud (OIC) simplifies integrations by offering prebuilt adapters, process orchestration, and mapping tools. It seamlessly connects Oracle Fusion Applications with external systems.
9. How do you configure approval workflows in Oracle Fusion?
A:
Approval workflows are configured using the BPM Worklist or the Approval Rules Engine. To streamline approvals, you can define conditions, hierarchies, and escalation rules.
10. What is the role of HCM Extracts in Oracle Fusion?
A:
HCM Extracts are used to extract HCM data for reporting, analytics, or integration. They allow users to define rules for selecting data and formatting it for external use.
11. What is your approach to Oracle Fusion Application security?
A:
Oracle Fusion uses Role-Based Access Control (RBAC). Users are assigned roles based on their job responsibilities, and security is managed through privileges and data access.
12. How do you debug issues with ESS jobs?
A:
Analyze the ESS job logs for errors.
Verify input parameters and configurations.
Re-execute after fixing the issue.
13. What is PaaS in Oracle Cloud?
A:
Platform as a Service (PaaS) is used to build custom applications or extend Oracle Fusion’s functionality without altering the base application.
14. What is ADFDI, and how is it different from FBDI?
A:
ADFDI (ADF Desktop Integration): Allows data upload and updates via Excel, providing a user-friendly interface.
FBDI: Handles bulk data imports using predefined templates.
15. How do you create a dashboard in OTBI?
A:
Create analyses using subject areas.
Add prompts for filtering.
Combine analyses into a dashboard layout.
Share the dashboard with users.
16. What are flexfields in Oracle Fusion?
A:
Users can add more data by using flex fields, which are fields that can be customized. They are categorized as:
Key Flexfields (KFF): For capturing structured data like accounting codes.
Descriptive Flexfields (DFF): For adding context-specific data.
17. How do you perform customizations in Oracle Fusion?
A:
Customizations can be done using:
Page Composer: For UI changes.
Application Composer: to incorporate extra fields or objects.
PaaS Extensions: For complex customizations.
18. How do you secure BI reports in Oracle Fusion?
A:
BI reports are secured by applying data roles and security privileges, ensuring that users only access relevant information.
