• What is the cause and solution for SAP error message RT825 - Performance attribute CPU: system calls ?

  The SAP error message RT825, which refers to "Performance attribute CPU: system calls," typically indicates that there is a performance issue related to the number of system calls being made by the SAP application. This can lead to increased CPU usage and can affect the overall performance of the SAP system.
  Cause:
  
  High Volume of System Calls: The application may be making an excessive number of system calls, which can occur due to inefficient coding, poorly optimized queries, or excessive data processing.
  Inefficient ABAP Code: ABAP programs that are not optimized can lead to unnecessary system calls, especially if they involve loops or database accesses that are not efficient.
  Database Performance: If the database is slow or not optimized, it can lead to increased system calls as the application waits for data.
  Network Latency: If the application is making calls to external systems or services, network latency can contribute to the performance issue.
  Configuration Issues: Incorrect configuration of the SAP system or the underlying database can also lead to performance bottlenecks.
  
  Solution:
  
  
  Code Optimization: Review and optimize ABAP code to reduce the number of system calls. This can include:
  
  Minimizing database accesses by using efficient SELECT statements.
  Avoiding nested loops and unnecessary processing.
  Using internal tables effectively to reduce the number of reads.
  
  
  
  Performance Analysis: Use transaction codes like ST05 (SQL Trace) and ST12 (ABAP Trace) to analyze performance and identify bottlenecks in the code or database queries.
  
  
  Database Tuning: Ensure that the database is properly tuned. This can include:
  
  Indexing frequently accessed tables.
  Analyzing and optimizing slow-running queries.
  Ensuring that the database statistics are up to date.
  
  
  
  System Monitoring: Use SAP Solution Manager or other monitoring tools to keep an eye on system performance and identify trends over time.
  
  
  Configuration Review: Review the configuration of the SAP system and the database to ensure that they are optimized for performance.
  
  
  Hardware Resources: Ensure that the hardware resources (CPU, memory, disk I/O) are adequate for the workload. Upgrading hardware may be necessary if the system is consistently under heavy load.
  
  
  Related Information:
  
  SAP Notes: Check for relevant SAP Notes that may provide specific guidance or patches related to performance issues.
  SAP Community: Engage with the SAP Community for insights and shared experiences from other users who may have faced similar issues.
  Performance Tuning Guides: Refer to SAP's official performance tuning guides for best practices in optimizing SAP applications and databases.
  
  By addressing the underlying causes and implementing the suggested solutions, you can mitigate the performance issues associated with the RT825 error message.
