• What is the cause and solution for SAP error message DB6134 - Maximum table change rate since the last statistics update ?

  The SAP error message DB6134, which indicates "Maximum table change rate since the last statistics update," typically arises when the database detects that a significant number of changes (inserts, updates, deletes) have occurred in a table since the last time statistics were updated. This can lead to performance issues because the query optimizer relies on accurate statistics to make informed decisions about how to execute queries efficiently.
  Cause:
  
  High Volume of DML Operations: A large number of data manipulation language (DML) operations (inserts, updates, deletes) have been performed on a table without updating its statistics.
  Outdated Statistics: The statistics for the table are outdated and do not reflect the current state of the data.
  Database Configuration: The database may have a threshold set for the maximum change rate, and if this threshold is exceeded, the error is triggered.
  
  Solution:
  
  
  Update Statistics: The primary solution is to update the statistics for the affected table. This can usually be done using the following SQL command:
  UPDATE STATISTICS <table_name>;
  In SAP, you can also use transaction codes like DB02 or DBACOCKPIT to manage database statistics.
  
  
  Schedule Regular Updates: Implement a regular schedule for updating statistics, especially for tables that experience high transaction volumes. This can help prevent the error from occurring in the future.
  
  
  Monitor Change Rates: Keep an eye on the change rates of your tables. If certain tables are frequently exceeding the threshold, consider optimizing the application logic or database design to reduce the frequency of changes.
  
  
  Adjust Database Parameters: If necessary, you can adjust the database parameters related to statistics collection and thresholds, but this should be done with caution and ideally in consultation with a database administrator.
  
  
  Related Information:
  
  Database Documentation: Refer to the documentation for your specific database (e.g., SAP HANA, Oracle, SQL Server) for detailed instructions on updating statistics and managing performance.
  SAP Notes: Check SAP Notes for any specific recommendations or patches related to this error message.
  Performance Monitoring: Use SAP tools like ST03N (Workload Analysis) and ST04 (Database Performance Analysis) to monitor performance and identify tables that may need attention.
  
  By addressing the underlying causes and implementing preventive measures, you can mitigate the occurrence of the DB6134 error and maintain optimal database performance.
