PROFILE
Harm Jan Stam
Harm Jan contributed to the Azure/sap-automation repository by engineering high availability and maintainability features for SAP HANA and DB2 clusters across RHEL and SUSE environments. He implemented active/active read-enabled SAP HANA system replication using Pacemaker and load balancers, enabling multi-node read distribution and reducing downtime for production workloads. His work included refactoring Ansible roles to simplify cluster resource management and removing redundant systemd configurations, which improved code maintainability. Additionally, he enhanced DB2 two-node clustering on RHEL8 and fixed user provisioning logic for sapadm, demonstrating depth in infrastructure as code, Linux administration, and cluster management using Shell and YAML.

Oct 1, 20242024-10 monthly summary for Azure/sap-automation focused on SAP HANA high availability (HA) enhancements and maintainability improvements. Delivered active/active read-enabled SAP HANA HA configuration with multi-node read distribution through a load balancer and active/read-enabled system replication using Pacemaker, significantly increasing read throughput and reducing downtime risk for production SAP workloads. Implemented a maintainability refactor of the SAP HANA Pacemaker cluster deployment on Red Hat by removing redundant systemd blocks and simplifying cluster resources management logic, resulting in a cleaner, more maintainable codebase and faster onboarding for future changes. This month’s work demonstrates strong business value through improved availability, read performance, and reduced operational debt. Technologies/skills demonstrated include Ansible, Pacemaker, Red Hat cluster configurations, SAP HANA replication, load balancing, and infrastructure as code.
