• What is the cause and solution for SAP error message ANST087 - No more roll memory available ?

  The SAP error message ANST087 "No more roll memory available" typically indicates that the system has run out of roll memory, which is used for storing user context and data during program execution. This can happen due to various reasons, such as high user load, inefficient programs, or insufficient memory allocation.
  Causes:
  
  High User Load: A large number of concurrent users can consume roll memory quickly.
  Inefficient Programs: Programs that use excessive memory or do not release memory properly can lead to roll memory exhaustion.
  Configuration Issues: Incorrect configuration of memory parameters in the SAP system can lead to insufficient roll memory.
  Insufficient Hardware Resources: The underlying hardware may not have enough memory to support the current workload.
  
  Solutions:
  
  
  Increase Roll Memory:
  
  You can increase the roll memory allocation in the SAP system profile parameters. The parameter rdisp/roll_area controls the size of the roll area. You can adjust this parameter in the instance profile.
  After making changes, restart the SAP instance for the changes to take effect.
  
  
  
  Optimize Programs:
  
  Review and optimize custom ABAP programs to ensure they are not consuming excessive memory. Look for memory leaks or inefficient data handling.
  Use transaction ST22 to check for dumps related to memory issues and analyze the code.
  
  
  
  Monitor User Load:
  
  Use transaction SM66 or SM50 to monitor active processes and user sessions. Identify and terminate any unnecessary sessions or processes that may be consuming roll memory.
  
  
  
  Check Memory Configuration:
  
  Review the memory configuration parameters in the instance profile, such as abap/heap_area_dia, abap/heap_area_nondia, and rdisp/roll_area, to ensure they are set appropriately for your system's workload.
  
  
  
  Increase Hardware Resources:
  
  If the system consistently runs out of roll memory, consider upgrading the hardware (e.g., adding more RAM) to accommodate the workload.
  
  
  
  Use Transaction RZ10:
  
  Use transaction RZ10 to modify the instance profile parameters and adjust memory settings as needed.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to memory management and roll memory issues for specific recommendations and best practices.
  Monitoring Tools: Utilize SAP monitoring tools like ST03N for workload analysis and ST04 for database performance to identify potential bottlenecks.
  Documentation: Refer to SAP documentation on memory management for detailed explanations of memory parameters and their impact on system performance.
  
  By addressing the underlying causes and implementing the suggested solutions, you should be able to resolve the ANST087 error and improve the overall performance of your SAP system.
