Copy of RT 239

What causes this issue?

The commit charge is the total memory (physical and virtual) that is
used by programs or by the operating system. The term is used in the
Windows NT Task Manager, and its maximum value should be smaller than
the available main memory.
The available commit charge is maximum value set by the operating
system (Commit Charge Limit in Task Manager) minus the currently used
commit charge (Commit Charge Total).

System Response

If the commit charge is larger than the real main memory, performance
suffers due to increased paging.

How to fix this error?

If the available commit charge falls below the threshold, you should
set the value to the complete operating system value for the Commit
Charge. Note, however, that an increased demand on virtual memory
causes more paging if there is not enough main memory available.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message RT600 - &1 &3 > &2 &3 (15 Min.) Commit Charge load exceeds threshold ?

  The SAP error message RT600 indicates that the commit charge load on the system has exceeded a predefined threshold. This typically relates to memory management in the SAP environment, particularly in relation to the amount of virtual memory that is being used by the SAP application server.
  Cause:
  
  High Memory Usage: The error usually occurs when the total amount of memory allocated to processes exceeds the available physical memory, leading to excessive paging or swapping.
  Configuration Issues: Incorrect configuration of the SAP system parameters, such as the instance profile settings, can lead to inefficient memory usage.
  Memory Leaks: Applications or processes that do not release memory properly can lead to increased memory consumption over time.
  Insufficient Hardware Resources: The server may not have enough physical memory to handle the workload, especially during peak times.
  
  Solution:
  
  Monitor Memory Usage: Use tools like SAP's transaction ST06 or ST02 to monitor memory usage and identify which processes are consuming the most memory.
  Adjust SAP Parameters: Review and adjust the SAP instance profile parameters related to memory management, such as abap/heap_area_total, abap/heap_area_dia, and abap/heap_area_nondia.
  Increase Physical Memory: If the server is consistently running out of memory, consider upgrading the physical RAM on the server.
  Optimize Code: Review custom ABAP code for potential memory leaks or inefficient memory usage patterns.
  Limit Background Jobs: If there are many background jobs running simultaneously, consider staggering their execution to reduce memory load.
  Check for System Updates: Ensure that the SAP system is up to date with the latest patches and updates, as these may contain performance improvements and bug fixes.
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to memory management and performance tuning for specific recommendations and best practices.
  Operating System Settings: Review the operating system's memory management settings, as they can also impact how memory is allocated and used by SAP.
  Performance Tuning: Regularly perform performance tuning and system health checks to ensure optimal operation of the SAP environment.
  Documentation: Refer to SAP's official documentation for guidelines on memory management and configuration settings.
  
  By addressing the underlying causes and implementing the suggested solutions, you can mitigate the occurrence of the RT600 error and improve the overall performance of your SAP system.
