Abstract

The in-memory architecture of SAP HANA has re-engineered the performance of the enterprise databases because it enables real-time analytics and transaction processing in a single application. Nevertheless, with the diversification of workloads, the effective regulation of resources has become critical to the stability of the systems and their performance. This paper offers in-depth research on smart resource management in SAP HANA with regard to three interrelated units, which are workload classes, admission control, system optimization using memory, CPU, and request-handling limits. The study is based on the findings of the publications (SAP S/4HANA 2022 release documentation, and performance management notes released in October 2022) which provide an insight into the state of workload classification and adaptive admission thresholds and predictive resource tuning. A unified structure is built by the study to correspond to the concepts of workload classification and adaptive admission threshold and predictive resource tuning. The results suggest that configuring the strategic workload classes and dynamic admission control can lead to the reduction of transaction latency by a factor of up to 30 percent and address CPU saturation in analogous analytical and transactional workloads. The suggested model focuses on optimization that is based on feedback, which allows proactive system parameters modification using real-time indicators. When brought together, SAP HANA environments can be able to deliver sustainable scalability, predictable query performance, and balanced utilization of the memory and compute resources. This paper offers a conceptual understanding as well as hands-on configuration advice to database architects, administrators, and performance engineers who want to optimize a current SAP landscape (SAP, 2022, October 12).
