• What is the cause and solution for SAP error message ITS119 - Size of allocatable virtual memory ?

  The SAP error message ITS119, which indicates "Size of allocatable virtual memory," typically arises when the SAP system is unable to allocate sufficient virtual memory for its operations. This can occur due to various reasons, including system configuration, memory limits set by the operating system, or resource constraints on the server.
  Causes:
  
  Operating System Limits: The operating system may impose limits on the amount of virtual memory that can be allocated to a single process or the entire system.
  Insufficient Physical Memory: If the server does not have enough physical memory (RAM), it may not be able to allocate the required virtual memory.
  Configuration Settings: Incorrect configuration settings in the SAP system or the underlying database can lead to memory allocation issues.
  Memory Leaks: Applications or processes that do not release memory properly can lead to exhaustion of available virtual memory.
  High Load: A sudden increase in load or concurrent users can lead to increased memory usage, causing the system to run out of allocatable memory.
  
  Solutions:
  
  
  Increase Virtual Memory Limits:
  
  On Unix/Linux systems, you can adjust the ulimit settings to allow for more virtual memory.
  On Windows, you may need to adjust the paging file size or virtual memory settings in the system properties.
  
  
  
  Check and Optimize Configuration:
  
  Review the SAP instance profile parameters related to memory allocation (e.g., abap/heap_area_dia, abap/heap_area_nondia, etc.) and adjust them as necessary.
  Ensure that the parameters are set according to the recommendations provided by SAP for your specific system configuration.
  
  
  
  Monitor and Manage Memory Usage:
  
  Use monitoring tools to track memory usage and identify any processes that may be consuming excessive memory.
  Consider restarting the SAP instance or the server if memory usage is unusually high.
  
  
  
  Upgrade Hardware:
  
  If the server consistently runs out of memory, consider upgrading the physical memory (RAM) or moving to a more powerful server.
  
  
  
  Review Application Code:
  
  If custom code or third-party applications are running on the SAP system, review them for potential memory leaks or inefficient memory usage.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for guidelines on memory management and configuration.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
  System Logs: Review system logs (e.g., dev_w0, dev_disp) for additional error messages or warnings that may provide more context about the memory allocation issue.
  
  By following these steps, you should be able to diagnose and resolve the ITS119 error related to virtual memory allocation in your SAP system.
