• What is the cause and solution for SAP error message DB6153 - The percentage of the pool logspace cleaners is too low ?

  The SAP error message DB6153, which states "The percentage of the pool logspace cleaners is too low," typically relates to the database's management of log space and the cleaning process for log segments. This error can occur in SAP systems that use databases like SAP HANA, Oracle, or others, and it indicates that the system is not able to efficiently manage the log space due to insufficient log space cleaners.
  Cause:
  
  Insufficient Log Space Cleaners: The error suggests that the number of log space cleaners (processes responsible for cleaning up log segments) is too low compared to the total log space available. This can lead to log space being filled up quickly, which can impact database performance and operations.
  Configuration Issues: The configuration settings for log space management may not be optimal, leading to inadequate cleaning processes.
  High Transaction Volume: A high volume of transactions can generate a lot of log data, which may overwhelm the existing log space cleaners.
  Resource Constraints: Limited system resources (CPU, memory) can prevent the log space cleaners from operating effectively.
  
  Solution:
  
  Increase the Number of Log Space Cleaners: Adjust the configuration to increase the number of log space cleaners. This can often be done through database configuration settings or parameters.
  Optimize Log Space Management Settings: Review and optimize the settings related to log space management. This may include adjusting thresholds or parameters that control how log space is allocated and cleaned.
  Monitor Transaction Volume: If the system is experiencing a high transaction volume, consider optimizing the application or database operations to reduce the load.
  Check System Resources: Ensure that the system has adequate resources (CPU, memory) to handle the log space cleaning processes. If necessary, consider upgrading hardware or optimizing resource allocation.
  Database Maintenance: Regularly perform database maintenance tasks, such as archiving old logs, to free up log space and improve performance.
  
  Related Information:
  
  Database Documentation: Refer to the specific database documentation for details on configuring log space cleaners and managing log space.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Monitoring Tools: Utilize monitoring tools to keep an eye on log space usage and the performance of log space cleaners.
  Performance Tuning: Consider engaging in performance tuning activities to optimize overall database performance, which may indirectly help with log space management.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with SAP support or a database administrator for further assistance.
