• What is the cause and solution for SAP error message DMC_RT_MSG071 - Computer &1: number of processors >= number of work processes ?

  The SAP error message DMC_RT_MSG071 indicates that the number of processors configured for the SAP system is less than the number of work processes defined. This can lead to performance issues, as the system may not be able to utilize all available resources effectively.
  Cause:
  
  Configuration Mismatch: The number of work processes defined in the SAP system profile is greater than the number of available processors on the server.
  Resource Allocation: The system is trying to allocate more work processes than the hardware can support, which can lead to contention and performance degradation.
  
  Solution:
  
  
  Adjust Work Processes:
  
  Access the SAP profile parameters (usually through transaction RZ10 or RZ11).
  Check the parameters related to work processes, such as rdisp/wp_no_dia, rdisp/wp_no_btc, etc.
  Reduce the number of work processes to match the number of available processors. A common recommendation is to have a ratio of 1 work process per processor, but this can vary based on the workload and system configuration.
  
  
  
  Increase Processor Count:
  
  If feasible, consider upgrading the hardware to add more processors to the server. This would allow you to increase the number of work processes without encountering this error.
  
  
  
  Review System Load:
  
  Analyze the current workload and performance metrics to determine if the number of work processes can be optimized further based on actual usage patterns.
  
  
  
  Restart the SAP System:
  
  After making changes to the work process configuration, restart the SAP system for the changes to take effect.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or updates related to this error message.
  Performance Monitoring: Use tools like ST03N (Workload Analysis) to monitor the performance and adjust the configuration accordingly.
  Documentation: Refer to the SAP Basis Administration Guide for best practices on configuring work processes and system resources.
  
  By addressing the configuration mismatch between the number of processors and work processes, you can resolve the error and improve the overall performance of your SAP system.
