How Oracle EBS Organizations Secure SharePoint Access While Moving Attachments Out of the Database

The Oracle EBS challenge: modern collaboration without compromising security

Oracle EBS remains a mission-critical system for finance, procurement, manufacturing, and asset management. At the same time, many organizations are under pressure to modernize how documents tied to EBS transactions are stored and shared.

Over time, attachments stored as database BLOBs create predictable problems:

• Oracle database growth that increases infrastructure, backup, and recovery costs
• Performance degradation as attachment volumes increase
• Limited document governance compared to modern collaboration platforms
• Difficulty meeting audit, retention, and accessibility expectations

For these reasons, many Oracle EBS organizations migrate attachments from the database to SharePoint Online. SharePoint improves collaboration, search, retention, and accessibility. However, this shift introduces a second challenge that is often underestimated.

What changes when Oracle EBS attachments move to SharePoint

When documents live inside Oracle EBS, access is implicitly controlled by the application. Once those documents are moved to SharePoint, access is governed by Microsoft Entra ID and group membership.

This creates a critical question for Oracle EBS teams:

How do we ensure SharePoint access reflects Oracle EBS user roles and responsibilities without introducing security risk?

Manual access management does not scale. Fully automated access changes can create concerns for security, audit, and compliance teams. Oracle EBS environments often require explicit oversight due to their support for regulated and financially sensitive workflows.

In this use case, Oracle EBS organizations aim to

• Reduce Oracle database growth by moving attachments to SharePoint
• Use Oracle EBS as the source of truth for document access decisions
• Align SharePoint library access with EBS responsibilities
• Maintain visibility and oversight of access changes

This is where AventX A2A fits.

Using Oracle EBS as the source of truth for SharePoint access

Oracle EBS already contains the logic that defines who should have access to documents. Responsibilities, roles, and user assignments reflect business rules that have evolved over time.

AventX A2A allows organizations to leverage that logic by syncing Oracle EBS query results with Microsoft Entra ID group membership. These groups are then used to control access to SharePoint document libraries that store Oracle EBS attachments.

This approach ensures:

• SharePoint access aligns with Oracle EBS responsibilities
• Changes in Oracle EBS users are reflected in document access
• IT avoids duplicating entitlement logic across systems

Balancing automation with governance

Many Oracle EBS organizations support automation, but still require governance. Security and audit teams often need clear visibility into:

• Who is being added or removed from access groups
• Why are those changes occurring
• Evidence that access decisions were reviewed

Instead of blindly enforcing changes, AventX A2A supports a governance-friendly workflow by generating email summaries of proposed Entra ID group changes based on Oracle EBS query results.

This allows teams to review recommended additions and removals before updates are applied, supporting separation of duties and audit requirements.

Why this matters after migrating Oracle EBS attachments

Once Oracle EBS attachments are moved to SharePoint, SharePoint becomes the system of engagement for documents.

Entra ID groups become the enforcement layer for access.

Without alignment between Oracle EBS users and Entra ID groups, organizations risk:

• Overexposing sensitive financial or operational documents
• Granting access based on outdated assumptions
• Failing audits due to unclear access change history

By combining attachment migration with Oracle EBS-driven group governance, organizations modernize document storage without creating new security gaps.

A practical Oracle EBS use case in action

A common scenario looks like this:

1. Oracle EBS attachments are migrated to SharePoint to reduce the database size
2. SharePoint document libraries are secured using Entra ID groups
3. Oracle EBS queries define group membership based on responsibilities
4. AventX A2A produces a clear summary of proposed access changes
5. Teams review and apply updates in line with internal security policies

While AventX A2A supports automated Entra ID changes, this user-based approach allows organizations to modernize document management while retaining confidence in access controls.

Who benefits most from this approach?

This use case is especially relevant for Oracle EBS organizations with:

• Finance, procurement, or HR data subject to audit controls
• SOX, ISO, or regulatory compliance requirements
• A need to reduce Oracle database growth without increasing access risk
• Security teams that require visibility into entitlement changes

It is also well-suited for organizations that want to move toward automation gradually, starting with review and validation before full enforcement.

Outcomes for Oracle EBS organizations

By aligning Oracle EBS user logic with SharePoint access governance, organizations achieve:

• Reduced Oracle database size and improved performance
• Better document usability and collaboration in SharePoint
• Consistent access control driven by Oracle EBS data
• Improved audit readiness and security oversight

Modernizing Oracle EBS document management is no longer optional, but neither is security. Moving attachments to SharePoint delivers real benefits only when access is governed with the same rigor as the ERP itself.

This use case shows how Oracle EBS organizations can reduce database growth, modernize document storage, and maintain strong access controls by aligning Oracle EBS user logic with Entra ID group governance.

Organizations that migrate attachments out of the Oracle database consistently see meaningful infrastructure and performance improvements. One real-world example of Oracle database reduction shows how a global manufacturer reduced database growth by moving Oracle EBS attachments to SharePoint.

If your Oracle EBS environment is growing due to attachments and your security team needs confidence in SharePoint access controls, this approach provides a practical path forward.
