Summary :
For optimal SAP HANA operation on RHEL for SAP HANA 6.7, specific Linux configurations are essential. Critical settings include the use of suited kernel versions and patches under Extended Update Support, which prevents unsupported upgrade issues and maintains certification validity. To enhance runtime performance, disable Transparent Hugepages (THP) to prevent potential memory management conflicts and system hangs. The system should be configured with the rpm package 'compat-sap-c++', and Transparent Hugepages should be disabled to resolve issues around memory mismanagement by SAP HANA. Additional steps involve adjusting C-states for reduced latency, and ensuring system stability with mandatory library versions to circumvent execution delays. It is critical to manage SELinux, tmpwatch, libssh2 package versions, and ensure proper configuration in /etc/sudoers for seamless SAP operations on RHEL.
