Summary :
The SAP Note addresses the AB as/4 system error PXA_NO_SHARED_MEMORY, which reflects issues in managing the Program Execution Area (PXA). This error manifests through a short dump, system log entries, recurring error messages indicating the system's unreadiness due to insufficient shared memory, and performance degradation. Additionally, updates to programs fail to trigger regeneration. The root of the issue stems from the system's inability to allocate sufficient memory for the PXA during startup, initializing only with minimal PXA capacity. The recommended solution involves checking and potentially adjusting the abap/buffer size profile parameter, ensuring adequate memory allocation per startup guidelines provided in the error's diagnostic tips.
