The SYS.TABLE_PRIVILEGES view in Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2 is a critical data dictionary view that provides metadata about table-level privileges granted to users, roles, or other database objects. This view is part of Oracle's foundational security infrastructure, enabling administrators to audit and manage access control within the EBS environment. Below is a detailed analysis of its structure, purpose, and relevance in Oracle EBS implementations.

1. Overview of SYS.TABLE_PRIVILEGES

The SYS.TABLE_PRIVILEGES view is a system-defined view owned by the SYS schema. It consolidates privilege-related metadata from underlying base tables, such as SYS.SYSAUTH$, and presents it in a readable format. This view is essential for querying granted privileges on tables, views, and other database objects, ensuring compliance with Oracle EBS security policies.

2. Key Columns and Their Significance

The view contains the following critical columns:

  • GRANTEE: Identifies the user, role, or object receiving the privilege.
  • OWNER: Specifies the schema owner of the table or object.
  • TABLE_NAME: The name of the table or view for which privileges are granted.
  • GRANTOR: The user or role that granted the privilege.
  • PRIVILEGE: The type of privilege (e.g., SELECT, INSERT, UPDATE, DELETE, REFERENCES, ALTER, INDEX).
  • GRANTABLE: Indicates whether the grantee can further grant the privilege (YES/NO).
  • HIERARCHY: Specifies if the privilege applies to hierarchical queries (Oracle-specific).

3. Role in Oracle EBS Security

In Oracle EBS, SYS.TABLE_PRIVILEGES plays a pivotal role in:

  • Access Control Audits: Administrators query this view to verify which users/roles have privileges on sensitive tables (e.g., AP_INVOICES_ALL, GL_JE_HEADERS).
  • Compliance Reporting It helps meet regulatory requirements (e.g., SOX, GDPR) by documenting privilege assignments.
  • Troubleshooting: Resolving "insufficient privileges" errors by identifying missing grants.

4. Integration with Oracle EBS Security Model

Oracle EBS leverages this view alongside its role-based access control (RBAC) framework:

  • Responsibility-to-Role Mapping: EBS responsibilities are linked to database roles, and privileges are queried via this view.
  • Customization Safeguards: Prevents unauthorized direct table access, enforcing use of APIs.
  • Patch Impact Analysis: Post-upgrade scripts often validate privilege consistency using this view.

5. Example Queries for EBS Administrators

Common use cases include: 

-- Check privileges on AP_INVOICES_ALL for a role:
SELECT * FROM SYS.TABLE_PRIVILEGES 
WHERE TABLE_NAME = 'AP_INVOICES_ALL' AND GRANTEE = 'AP_USER_ROLE';

-- List all privileges granted by a specific user:
SELECT GRANTEE, TABLE_NAME, PRIVILEGE 
FROM SYS.TABLE_PRIVILEGES 
WHERE GRANTOR = 'SYSADMIN';

6. Limitations and Best Practices

While powerful, administrators should note:

  • Performance Impact: Queries on this view can be resource-intensive in large EBS instances.
  • Data Sensitivity: Direct modifications to underlying tables are unsupported.
  • Alternative Views: For user-centric analysis, USER_TAB_PRIVS or DBA_TAB_PRIVS may be preferable.

7. Conclusion

The SYS.TABLE_PRIVILEGES view is indispensable for securing Oracle EBS environments. By providing visibility into table-level permissions, it enables robust security governance, compliance adherence, and operational troubleshooting. EBS administrators should incorporate this view into routine security audits and access control workflows.
