User Access Review (UAR) is a vital control in SAP security governance to ensure users have appropriate access based on their roles and responsibilities. However, when organizations implement UAR processes, they must also consider high availability (HA) requirements to ensure continuous access review operations without downtime or disruption—especially in critical SAP environments.
This article explores best practices and technical considerations for configuring SAP User Access Review with a focus on achieving high availability and business continuity.
SAP landscapes often support mission-critical business functions, and UAR is integral to security, compliance, and risk mitigation. Interruptions in access review processes can lead to:
By architecting UAR with HA in mind, organizations ensure that access certifications, reviews, and approvals continue seamlessly—even in the event of system failures, maintenance windows, or infrastructure disruptions.
Redundant Infrastructure for UAR Tools
Whether using SAP GRC Access Control, SAP Identity Access Governance (IAG), or third-party access governance tools, deploying these solutions on redundant servers or cloud instances ensures availability if a node fails.
Load Balancing and Failover
Implement load balancers and failover mechanisms for the application servers hosting UAR modules. This prevents single points of failure and distributes user review workloads efficiently.
Database High Availability
The underlying databases storing user access data and review results should support HA features such as clustering, replication, or synchronous mirroring (e.g., SAP HANA System Replication, Oracle RAC). This ensures no data loss and fast recovery.
Integration Redundancy with SAP Systems
UAR solutions integrate with various SAP applications (SAP S/4HANA, ECC, SuccessFactors, Ariba). Ensuring these integration points are highly available is critical to obtain real-time access data and avoid disruptions in the review cycle.
Automated Workflow Resilience
Design access review workflows that can resume gracefully after failovers or interruptions. This includes persisting the workflow state and notifications to reviewers/managers without loss.
Backup and Disaster Recovery Plans
Regularly back up UAR configurations, user access data, and workflow histories. Test disaster recovery procedures to guarantee rapid restoration of access review operations after catastrophic events.
Step 1: Assess the Current Landscape
Identify components involved in your UAR process: Access governance tools, application servers, databases, and integration points. Evaluate their existing HA capabilities.
Step 2: Implement Redundant Components
Deploy additional application servers for SAP GRC or IAG in an HA cluster. Use cloud-based services with multi-region availability zones if applicable.
Step 3: Configure Load Balancers and Failover
Set up load balancers (e.g., F5, AWS ELB) to distribute traffic and detect failed nodes to redirect requests automatically.
Step 4: Enable Database HA Features
Leverage database-level HA solutions (SAP HANA System Replication, Oracle RAC, MS SQL Always On) to protect critical access review data.
Step 5: Establish Reliable Integration Channels
Use SAP Cloud Platform Integration or middleware that supports HA to maintain stable data flows between SAP applications and UAR tools.
Step 6: Design Fault-Tolerant Workflows
Use workflow engines with checkpointing and retry mechanisms to prevent workflow loss during disruptions.
Step 7: Conduct Regular Testing and Monitoring
Periodically test failover scenarios and monitor the health of all UAR components with tools like SAP Solution Manager or third-party monitoring suites.
| Challenge | Solution/Recommendation |
|---|---|
| Complexity in HA Setup | Collaborate with SAP Basis, Security, and Infrastructure teams for architecture design. |
| Increased Cost for Redundancy | Balance between required uptime and cost; prioritize critical components for HA. |
| Synchronizing Data Across Systems | Use robust middleware and replication tools to maintain data consistency. |
| Workflow Failures on Failover | Implement checkpoint and resume features in workflows to minimize impact. |
Configuring SAP User Access Review with high availability is essential for organizations aiming to maintain robust security governance and compliance in their SAP ecosystems. By leveraging redundant infrastructure, failover mechanisms, database replication, and resilient workflows, organizations can ensure uninterrupted access review processes—even amid technical challenges.
A well-architected HA strategy not only reduces operational risks but also strengthens the overall trustworthiness of SAP user access controls, contributing to a secure and compliant enterprise environment.
