Summary :
This SAP Note outlines the required JVM settings for SAP Java applications on J2EE Engine 6.40/7.0, recommending using SAP JVM 4 post-October 2012. It details the unavailability of support for non-SAP JDKs since then and specifies JVM settings not adhering to standard configuration templates, which are exclusive to new installations based on J2EE Engine 6.40 SP7 or higher. Key focus includes parameter adjustment via ConfigTool and references to various notes for platform-specific configurations. Emphasis is laid on maintaining correct heap sizes to prevent memory overflow and ensuring all settings are aligned with physical memory to avoid OS paging. Additional tips cover using server VMs, setting heap sizes based on platform architecture (32-bit or 64-bit), and guidelines for modifying thread pools and verbose GC usage.
