• What is the cause and solution for SAP error message SDBALM124 - Cache accesses (total) - for calculation of the access hitrates ?

  The SAP error message SDBALM124 indicates an issue related to the cache accesses in the SAP system, specifically concerning the calculation of access hit rates. This message is part of the SAP database performance monitoring and is typically associated with the Database Performance Monitor (DBPM) or the SAP Solution Manager.
  Cause:
  The error message SDBALM124 is triggered when the system detects that the cache accesses (total) are not being calculated correctly. This can happen due to several reasons, including:
  
  Insufficient Cache Configuration: The cache may not be configured optimally, leading to a high number of cache misses.
  Database Performance Issues: If the database is under heavy load or experiencing performance issues, it may not be able to serve requests from the cache effectively.
  Monitoring Configuration: There may be issues with the configuration of the monitoring tools or the data collection process, leading to inaccurate reporting of cache accesses.
  Data Volume: A high volume of data or complex queries can lead to increased cache accesses and misses.
  
  Solution:
  To resolve the SDBALM124 error, consider the following steps:
  
  
  Check Cache Configuration:
  
  Review the cache settings in your SAP system and ensure they are configured according to best practices for your specific database and workload.
  Adjust the cache size if necessary to accommodate the workload.
  
  
  
  Monitor Database Performance:
  
  Use transaction codes like ST04 (Database Performance Analysis) or ST03 (Workload Analysis) to monitor database performance.
  Identify any long-running queries or performance bottlenecks that may be affecting cache performance.
  
  
  
  Review Monitoring Configuration:
  
  Ensure that the monitoring tools (like DBPM) are correctly configured and that data collection is functioning as expected.
  Check for any updates or patches for the monitoring tools that may address known issues.
  
  
  
  Analyze Workload:
  
  Analyze the workload on the database to identify any patterns or specific transactions that are causing excessive cache accesses.
  Optimize queries or adjust application logic to reduce the load on the database.
  
  
  
  Consult SAP Notes:
  
  Search for relevant SAP Notes in the SAP Support Portal that may address this specific error message or provide guidance on cache performance issues.
  
  
  
  Engage SAP Support:
  
  If the issue persists after taking the above steps, consider reaching out to SAP Support for further assistance. Provide them with detailed information about your system configuration, workload, and any steps you have already taken.
