How To Fix RT238 - Monitoring object: commit charge

SAP Error Message - Details

• Message type: E = Error

• Message class: RT - Monitoring infrastructure MSG and alert texts

• Message number: 238

• Message text: Monitoring object: commit charge

What causes this issue?

The commit charge is the complete 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.

System Response

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

• What is the cause and solution for SAP error message RT238 - Monitoring object: commit charge ?

  The SAP error message RT238, which refers to "Monitoring object: commit charge," typically indicates an issue related to memory management within the SAP system. This error is often associated with the system's inability to allocate sufficient memory for its operations, which can lead to performance degradation or even system crashes.
  Cause:
  
  Insufficient Memory Allocation: The SAP system may not have enough memory allocated to handle the current workload, leading to a high commit charge.
  Memory Leaks: There may be memory leaks in the application or in the underlying database, causing the system to consume more memory over time.
  Configuration Issues: Incorrect configuration of the SAP memory parameters (like abap/heap_area_total, abap/heap_area_dia, etc.) can lead to inefficient memory usage.
  High Workload: A sudden increase in user activity or background jobs can lead to a spike in memory usage.
  Database Issues: Problems with the database, such as inefficient queries or locks, can also contribute to high memory usage.
  
  Solution:
  
  Monitor Memory Usage: Use transaction codes like ST02 (Tune Summary) and ST03 (Workload Analysis) to monitor memory usage and identify bottlenecks.
  Adjust Memory Parameters: Review and adjust the SAP memory parameters in the instance profile. Ensure that the parameters are set according to the system's requirements and available resources.
  Check for Memory Leaks: Analyze the system for potential memory leaks. This may involve reviewing custom code, background jobs, and third-party add-ons.
  Optimize Workload: If there is a sudden increase in workload, consider optimizing the workload by scheduling background jobs during off-peak hours or increasing system resources temporarily.
  Database Optimization: Ensure that the database is optimized. This may involve analyzing slow queries, indexing, and ensuring that the database is properly configured.
  Increase Physical Memory: If the system consistently runs out of memory, consider increasing the physical memory of the server hosting the SAP system.
  
  Related Information:
  
  SAP Notes: Check for relevant SAP Notes that may provide specific guidance or patches related to memory management and the RT238 error.
  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 (transaction SM21) for any additional error messages or warnings that may provide more context about the memory issue.
  Performance Tuning: Regularly perform performance tuning and system health checks to prevent memory-related issues from arising.
  
  By addressing the underlying causes and implementing the suggested solutions, you can mitigate the impact of the RT238 error and improve the overall performance of your SAP system.
