• What is the cause and solution for SAP error message VIRT364 - Min. total phys. CP Usage ?

  The SAP error message VIRT364, which indicates "Min. total phys. CP Usage," typically relates to issues with the configuration of the SAP system's virtual memory or physical memory settings. This error can occur when the system's physical CPU usage falls below a certain threshold, which can affect performance and system stability.
  Cause:
  
  Insufficient Physical Resources: The system may not have enough physical CPUs or memory allocated to handle the workload.
  Configuration Issues: The SAP system parameters may not be optimally configured for the current workload or hardware.
  High Load on the System: If the system is under heavy load, it may not be able to allocate resources effectively.
  Virtualization Issues: If the SAP system is running in a virtualized environment, there may be resource allocation issues with the hypervisor.
  
  Solution:
  
  Check System Resources: Monitor the physical CPU and memory usage on the server. Ensure that there are enough resources available for the SAP system.
  Adjust SAP Parameters: Review and adjust the SAP instance profile parameters related to CPU and memory usage. Parameters such as rdisp/num_wp (number of work processes) and abap/heap_area_dia (dialog heap size) may need to be tuned.
  Optimize Workload: Analyze the workload on the system and optimize it. This may involve redistributing tasks or optimizing long-running processes.
  Increase Physical Resources: If the server is consistently under heavy load, consider upgrading the physical hardware (adding more CPUs or memory).
  Review Virtualization Settings: If running in a virtualized environment, ensure that the virtual machine has been allocated sufficient resources and that the hypervisor settings are optimized for performance.
  SAP Notes and Support: Check for any relevant SAP Notes that may address this specific error or provide additional guidance. You can search the SAP Support Portal for updates or patches that may resolve the issue.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for guidelines on system performance and resource management.
  Monitoring Tools: Utilize SAP monitoring tools like SAP Solution Manager or transaction codes such as ST03N (Workload Analysis) to analyze system performance.
  Performance Tuning: Consider engaging with SAP Basis consultants or performance tuning experts if the issue persists, as they can provide specialized insights and recommendations.
  
  By addressing the underlying causes and implementing the suggested solutions, you should be able to resolve the VIRT364 error and improve the performance of your SAP system.
