The FND_OAM_FORMS_RTI table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical repository table that stores runtime information related to Oracle Application Manager (OAM) forms. This table is part of the Oracle Application Framework (OAF) and plays a key role in managing form-based interactions within the EBS environment. Below is a detailed analysis of its structure, purpose, and significance.

1. Purpose and Functional Role

The FND_OAM_FORMS_RTI table primarily serves as a runtime repository for form-related metadata and transactional data used by Oracle Application Manager. It captures real-time execution details of forms, including session-specific attributes, navigation history, and state management. This table ensures that form-based applications maintain consistency during user interactions, particularly in multi-step processes or complex workflows.

2. Key Columns and Data Structure

The table consists of several important columns, including:
  • RTI_ID: A unique identifier for each runtime instance.
  • FORM_ID: References the form definition from FND_FORMS or related metadata tables.
  • SESSION_ID: Links to the user session in FND_SESSIONS.
  • STATUS: Indicates the current state (e.g., ACTIVE, COMPLETED, ERROR).
  • CREATION_DATE and LAST_UPDATE_DATE: Timestamps for auditing.
  • ATTRIBUTE1-ATTRIBUTEn: Custom fields for extensibility.
These columns enable tracking of form interactions, troubleshooting, and performance analysis.

3. Integration with Oracle Application Manager (OAM)

The table is tightly integrated with OAM's monitoring and diagnostic capabilities. It allows administrators to:
  • Track active form sessions for performance tuning.
  • Diagnose issues by analyzing runtime errors or hangs.
  • Audit user navigation paths for compliance.

4. Technical Considerations

In EBS 12.2.2, the table may leverage Oracle RAC (Real Application Clusters) for high availability. Partitioning strategies are often employed to manage large datasets efficiently. The table is indexed on key columns like RTI_ID, SESSION_ID, and FORM_ID to optimize query performance.

5. Customization and Extensibility

While primarily used by Oracle's seeded functionality, the table can be extended via custom attributes to support bespoke requirements. However, direct DML operations are discouraged; APIs like FND_OAM_FORMS_PKG should be used instead.

6. Maintenance and Performance

Regular purging of stale records via concurrent programs is recommended to prevent table bloating. In EBS 12.2.2, the table benefits from In-Memory Column Store (IMCS) optimizations when configured.

7. Security Implications

Access to this table should be restricted due to its sensitive runtime data. Oracle's Virtual Private Database (VPD) policies may be applied in 12.2.2 for row-level security.

Conclusion

The FND_OAM_FORMS_RTI table is a foundational component in Oracle EBS for managing form runtime states. Its design reflects Oracle's emphasis on scalability and diagnosability, particularly in complex enterprise deployments. Understanding this table is essential for EBS administrators and developers working on form customization or performance optimization.
