Résumé :
SAP Note discusses Zero Administration Memory Management (ZAMM) for Windows platforms, specifically addressing its operation on both 32-bit and 64-bit systems. This mode of memory management requires no manual configurations, adapting itself dynamically to varying memory needs. Key functions include the self-extending capacity of extended memory starting with a base specified by PHYS_MEMSIZE and extending in accordance with user requirements and system limitations, set by em/max_size_MB and the size of the Windows page file. Furthermore, SAP Note details optimal default settings for various memory management parameters up to kernel version 7.20, and as of version 7.40, variable parameter values are supported. Implementation suggestions include ensuring minimal file cache size through appropriate Windows setting and potential customer-specific adjustments post-EarlyWatch Session evaluations.
