PROFILE
Harm Jan Stam
Worked on the Azure/sap-automation repository to deliver high availability and maintainability enhancements for SAP HANA and DB2 clusters across RHEL and SUSE environments. Developed active/active read-enabled SAP HANA configurations using Ansible and Pacemaker, enabling multi-node read distribution through load balancers and improving system replication. Refactored cluster deployment logic to remove redundant code and simplify resource management, resulting in a more maintainable codebase. Addressed user provisioning and security for sapadm in SDAF and enhanced DB2 two-node clustering with resource prioritization and fencing improvements. Demonstrated expertise 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.
