• What is the cause and solution for SAP error message VIRT273 - DB + non-DB faults ?

  The SAP error message VIRT273 typically indicates a problem related to virtual memory management in the SAP system, specifically concerning database (DB) and non-database (non-DB) faults. This error can arise due to various reasons, including insufficient memory allocation, configuration issues, or resource contention.
  Causes of VIRT273 Error
  
  
  Insufficient Memory Allocation: The SAP system may not have enough memory allocated to handle the workload, leading to faults when trying to access virtual memory.
  
  
  Configuration Issues: Incorrect configuration settings in the SAP system or the underlying database can lead to inefficient memory usage.
  
  
  Resource Contention: High load on the system or competing processes can lead to increased faults as the system struggles to allocate memory.
  
  
  Database Performance Issues: If the database is not optimized or is experiencing performance issues, it can lead to increased faults.
  
  
  Operating System Limits: The operating system may have limits on memory usage that are being exceeded by the SAP application.
  
  
  Solutions to VIRT273 Error
  
  
  Increase Memory Allocation: Review and increase the memory settings for the SAP instance. This can be done by adjusting parameters in the SAP profile (e.g., abap/heap_area_total, abap/heap_area_dia, etc.).
  
  
  Optimize Configuration: Check the configuration settings for both the SAP system and the database. Ensure that they are optimized for the current workload.
  
  
  Monitor System Performance: Use monitoring tools to analyze system performance and identify any bottlenecks. This can help in understanding if there are any resource contention issues.
  
  
  Database Optimization: Ensure that the database is properly indexed and optimized. Regular maintenance tasks such as updating statistics and reorganizing tables can help improve performance.
  
  
  Check Operating System Settings: Review the operating system settings for memory limits and adjust them if necessary. This may involve increasing the limits on shared memory or other relevant parameters.
  
  
  Review SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
  
  
  Consult with Basis Team: If the issue persists, it may be beneficial to consult with your SAP Basis team or a technical consultant who can provide deeper insights into the system configuration and performance.
  
  
  Related Information
  
  
  SAP Notes: Always check for the latest SAP Notes related to memory management and performance issues. SAP frequently updates its documentation and provides fixes for known issues.
  
  
  Monitoring Tools: Utilize SAP monitoring tools such as SAP Solution Manager or transaction codes like ST02 (buffer management) and ST04 (database performance) to analyze memory usage and performance.
  
  
  System Logs: Review system logs (transaction SM21) for any additional error messages or warnings that may provide more context about the issue.
  
  
  Performance Tuning: Consider conducting a performance tuning exercise to identify and resolve any underlying issues that may be contributing to the error.
  
  
  By addressing the underlying causes and implementing the suggested solutions, you can mitigate the VIRT273 error and improve the overall performance of your SAP system.
