• What is the cause and solution for SAP error message VIRT196 - Memory Configured ?

  The SAP error message VIRT196 typically indicates that there is an issue related to memory configuration in the SAP system. This error can arise due to various reasons, including insufficient memory allocation for the SAP application server or improper configuration settings.
  Cause:
  
  Insufficient Memory Allocation: The SAP instance may not have enough memory allocated to handle the workload, leading to performance issues or crashes.
  Configuration Errors: Incorrect settings in the SAP profile parameters related to memory management can trigger this error.
  Operating System Limits: The operating system may impose limits on memory usage that affect the SAP instance.
  Resource Contention: Other applications or processes running on the same server may be consuming excessive memory, leaving insufficient resources for SAP.
  
  Solution:
  
  
  Check Memory Allocation:
  
  Review the memory settings in the SAP profile (e.g., DEFAULT.PFL, instance profile).
  Ensure that parameters like abap/heap_area_dia, abap/heap_area_nondia, and rdisp/PG_MAXFS are set appropriately based on the system's workload and available resources.
  
  
  
  Adjust Operating System Settings:
  
  Check the operating system's memory limits and adjust them if necessary. This may involve modifying kernel parameters or system settings to allow more memory for the SAP instance.
  
  
  
  Monitor Resource Usage:
  
  Use monitoring tools to check memory usage by the SAP instance and other processes on the server. Identify any processes that are consuming excessive memory and take appropriate action (e.g., optimizing or terminating those processes).
  
  
  
  Increase Physical Memory:
  
  If the server is consistently running out of memory, consider upgrading the physical memory (RAM) on the server to accommodate the needs of the SAP system.
  
  
  
  Review SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide guidance on memory configuration best practices.
  
  
  
  Restart the SAP Instance:
  
  In some cases, a simple restart of the SAP instance may help clear temporary memory issues.
  
  
  
  Related Information:
  
  SAP Memory Management: Understanding how SAP manages memory can help in configuring the system optimally. SAP uses different memory areas for dialog processes, background processes, and other operations.
  SAP Kernel Version: Ensure that you are using a supported and up-to-date version of the SAP kernel, as memory management improvements are often included in updates.
  Performance Tuning: Regular performance tuning and monitoring can help prevent memory-related issues from arising in the future.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with SAP support or a qualified SAP Basis consultant for further assistance.
