Summary :
This SAP Note outlines the crucial settings for R/3 Memory Management, essential for optimal system performance and error prevention in SAP R/3 environments. It combines previous notes based on recommendations from the Basis development group and customer experiences, provided by SAP's Technical Core Competence Center (TCC). Adjustments have been added for AS/400 and HP-UX systems, with guidelines on configuring R/3 Buffer, Roll Memory, and additional buffers across various operating systems including Windows NT and UNIX derivatives, ensuring system stability and performance. Specific buffer size parameters and thresholds for different environments are detailed to avoid potential runtime errors and performance issues.
