• What is the cause and solution for SAP error message DB6PM224 - Table has been set VOLATILE and will be excluded from Automatic RUNSTATS ?

  The SAP error message DB6PM224 indicates that a specific database table has been marked as "VOLATILE," which means that it is not eligible for automatic statistics collection (RUNSTATS) by the database management system. This can affect query performance, as the database optimizer relies on accurate statistics to generate efficient execution plans.
  Cause:
  
  Volatile Tables: The table in question is defined as volatile, which typically means that it is expected to change frequently or is used for temporary data. As a result, the database system does not automatically collect statistics for these tables to avoid the overhead of frequent updates.
  Database Configuration: The database settings may have been configured to treat certain tables as volatile based on their usage patterns or definitions.
  
  Solution:
  
  Manual RUNSTATS: You can manually collect statistics for the volatile table using the appropriate SQL command (e.g., RUNSTATS in DB2). This will help the optimizer make better decisions for query execution.
  RUNSTATS ON TABLE your_table_name;
  
  Review Table Design: If the table is not truly volatile, consider changing its definition to allow for automatic statistics collection. This may involve altering the table properties or re-evaluating its usage.
  Adjust Database Settings: If applicable, review the database configuration settings to see if the criteria for marking tables as volatile can be adjusted.
  Monitor Performance: After collecting statistics, monitor the performance of queries that access the volatile table to ensure that the changes have had a positive impact.
  
  Related Information:
  
  Database Documentation: Refer to the documentation for your specific database system (e.g., DB2, Oracle, etc.) for details on how to manage statistics and the implications of volatile tables.
  SAP Notes: Check SAP Notes for any specific recommendations or patches related to this error message.
  Performance Tuning: Consider engaging in broader performance tuning efforts if you frequently encounter issues with query performance related to volatile tables.
  
  By addressing the underlying causes and implementing the suggested solutions, you can mitigate the impact of the DB6PM224 error message on your SAP system's performance.
