• What is the cause and solution for SAP error message CCMS_AGENT026 - Memory released by Garbage Collections per minute ?

  The SAP error message CCMS_AGENT026 indicates that the memory released by garbage collection in the Java Virtual Machine (JVM) is being reported. This message is part of the monitoring capabilities of the SAP system, specifically related to the performance and memory management of the Java stack.
  Cause:
  
  High Memory Usage: The JVM is experiencing high memory usage, which triggers frequent garbage collection (GC) processes to reclaim memory.
  Memory Leaks: There may be memory leaks in the application, causing the JVM to retain objects that are no longer needed, leading to increased garbage collection activity.
  Configuration Issues: The JVM may not be optimally configured for the workload, leading to inefficient memory management.
  Application Behavior: Certain applications or processes may be consuming more memory than expected, leading to increased garbage collection.
  
  Solution:
  
  Monitor Memory Usage: Use tools like the SAP Java Management Console (JMC) or other monitoring tools to analyze memory usage patterns and identify potential memory leaks.
  Optimize JVM Parameters: Adjust the JVM parameters (such as heap size, garbage collection algorithms, etc.) to better suit the application's needs. This can help reduce the frequency and duration of garbage collection.
  Analyze Code: Review the application code for potential memory leaks. Look for objects that are not being released properly and ensure that resources are being managed correctly.
  Update Software: Ensure that you are using the latest version of the SAP software and JVM, as updates may include performance improvements and bug fixes related to memory management.
  Increase Heap Size: If the application legitimately requires more memory, consider increasing the heap size allocated to the JVM.
  Use Profiling Tools: Utilize profiling tools to analyze memory usage and identify objects that are consuming excessive memory.
  
  Related Information:
  
  Garbage Collection Types: Familiarize yourself with different types of garbage collection (e.g., minor GC, major GC) and their impact on performance.
  SAP Notes: Check SAP Notes for any known issues or recommendations related to memory management and garbage collection for your specific version of SAP.
  Performance Tuning: Consider engaging in performance tuning exercises to optimize the overall performance of the SAP system, which may indirectly reduce garbage collection frequency.
  Documentation: Refer to SAP documentation for best practices on JVM configuration and memory management.
  
  By addressing the underlying causes of the CCMS_AGENT026 message, you can improve the performance and stability of your SAP system.
