• What is the cause and solution for SAP error message D4407 - SAP/OS400 roll mangagement: Free user management - current total space ?

  The SAP error message D4407, which pertains to "SAP/OS400 roll management: Free user management - current total space," typically indicates that the roll area (the space allocated for storing user context and data during program execution) is full or nearing its limit. This can lead to issues with user sessions and overall system performance.
  Cause:
  
  Insufficient Roll Area Size: The roll area may not be adequately sized to handle the current workload, especially if there are many concurrent users or if the applications being run are particularly memory-intensive.
  High User Load: A sudden increase in the number of active users or processes can lead to the roll area being filled up quickly.
  Long-Running Transactions: Transactions that take a long time to complete can consume roll space, leading to exhaustion of available resources.
  Configuration Issues: Incorrect configuration settings for roll area parameters in the SAP system can also contribute to this issue.
  
  Solution:
  
  
  Increase Roll Area Size:
  
  You can increase the roll area size by adjusting the parameters in the SAP profile. The parameters to look for are rdisp/roll_area and rdisp/roll_max_size.
  Use transaction RZ10 to modify the instance profile and increase the roll area size. After making changes, restart the SAP instance for the changes to take effect.
  
  
  
  Monitor User Sessions:
  
  Regularly monitor the number of active user sessions and the memory consumption of transactions. This can help identify if there are specific transactions that are consuming excessive roll space.
  
  
  
  Optimize Long-Running Transactions:
  
  Review and optimize any long-running transactions to ensure they are not consuming unnecessary roll space. This may involve code optimization or breaking down large transactions into smaller, more manageable ones.
  
  
  
  Check for Memory Leaks:
  
  Investigate if there are any memory leaks in custom programs or third-party add-ons that could be causing excessive roll space consumption.
  
  
  
  Adjust User Management Settings:
  
  Review the user management settings in the SAP system to ensure they are configured correctly for your environment.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to roll area management and performance tuning for specific recommendations and best practices.
  Transaction Codes: Use transaction codes like SM50 (Process Overview) and SM66 (Global Process Overview) to monitor active processes and their memory usage.
  System Monitoring: Utilize tools like SAP Solution Manager or other monitoring tools to keep an eye on system performance and resource utilization.
  
  By addressing the roll area size and monitoring user activity, you can mitigate the occurrence of the D4407 error and improve overall system performance.
