Summary :
This SAP Note provides guidelines for configuring optimal settings when operating SAP HANA SPS10 or SPS11 on SLES 11 SP4 and SLES 11 for SAP SP4. Key recommendations include disabling transparent hugepages due to potential performance issues with HANA's memory management, adjusting C-States for reduced latency in Linux, and removing the ulimit package which imposes system-wide resource limitations. Other advisories focus on setting the Linux pagecache limit, managing compiler runtime environments, and addressing specific issues with NFSv4 and XFS for HANA persistence. Each configuration suggestion aims to enhance system performance and stability, with steps provided for both runtime changes and persistence post-reboot.
