• What is the cause and solution for SAP error message ITS039 - Number of Web GUI requests per second ?

  The SAP error message ITS039, which indicates that the number of Web GUI requests per second has exceeded the configured limit, typically arises in the context of SAP's Internet Transaction Server (ITS) when the system is under heavy load or when there are too many concurrent requests being processed.
  Cause:
  
  High Load: The system is experiencing a high volume of requests, which exceeds the configured threshold for the number of Web GUI requests that can be processed per second.
  Configuration Settings: The default settings for the maximum number of requests per second may be too low for the current usage patterns.
  Inefficient Queries: Some transactions or queries may be taking longer to process, leading to a backlog of requests.
  Network Issues: Latency or network issues can cause delays in processing requests, leading to a higher number of requests being queued.
  
  Solution:
  
  
  Increase Request Limit: 
  
  You can increase the limit for the number of Web GUI requests per second in the ITS configuration. This can typically be done in the sapwebdisp.pfl or its.conf file, depending on your setup.
  Look for parameters like max_requests_per_second and adjust them according to your system's capacity and expected load.
  
  
  
  Optimize Performance:
  
  Review and optimize the performance of the transactions that are being accessed. This may involve optimizing database queries, improving application logic, or enhancing the overall system performance.
  Monitor the performance of the backend systems to ensure they are not causing bottlenecks.
  
  
  
  Load Balancing:
  
  If you have multiple application servers, consider implementing load balancing to distribute the requests more evenly across the servers.
  
  
  
  Monitor System Load:
  
  Use monitoring tools to keep an eye on system performance and request load. This can help you identify peak usage times and adjust configurations accordingly.
  
  
  
  Review Network Configuration:
  
  Ensure that there are no network issues causing delays in request processing. Check for bandwidth limitations, latency, and other network-related problems.
