• What is the cause and solution for SAP error message DB02018 - &1 segments with PCTINCREASE set > threshold of &2 ?

  The SAP error message DB02018 indicates that the number of segments in a database table has exceeded a specified threshold due to the PCTINCREASE parameter being set higher than the allowed limit. This typically occurs in the context of database management, particularly with Oracle databases, where the PCTINCREASE parameter controls the growth of segments (like tables or indexes) in the database.
  Cause:
  
  PCTINCREASE Setting: The PCTINCREASE parameter determines how much space a segment will grow when it needs to allocate more space. If this value is set too high, it can lead to excessive growth of segments, which can cause performance issues and resource management problems.
  Threshold Exceeded: The error message indicates that the number of segments has exceeded a predefined threshold, which can be a result of the high PCTINCREASE setting leading to rapid growth of segments.
  
  Solution:
  
  
  Review and Adjust PCTINCREASE:
  
  Check the current PCTINCREASE setting for the affected segments.
  Consider lowering the PCTINCREASE value to a more reasonable level (e.g., 0 or a small percentage) to control the growth of segments more effectively.
  You can alter the segment's storage parameters using SQL commands like:
  ALTER TABLE table_name STORAGE (PCTINCREASE new_value);
  
  Replace table_name with the actual name of the table and new_value with the desired percentage.
  
  
  
  Monitor Segment Growth:
  
  Regularly monitor the growth of database segments to ensure they do not exceed acceptable limits.
  Use database monitoring tools or queries to track segment sizes and growth patterns.
  
  
  
  Database Maintenance:
  
  Perform regular database maintenance tasks, such as reorganizing or rebuilding segments, to optimize performance and manage space effectively.
  Consider partitioning large tables if applicable, which can help manage growth and improve performance.
  
  
  
  Consult Documentation:
  
  Refer to the SAP and database documentation for specific guidelines on managing segment growth and storage parameters.
  
  
  
  Related Information:
  
  Database Management: Understanding how your specific database (e.g., Oracle, SQL Server) handles segment management and storage parameters is crucial.
  SAP Notes: Check SAP Notes for any specific recommendations or patches related to this error message.
  Performance Tuning: Consider engaging in performance tuning practices to optimize database performance and resource usage.
  
  By addressing the PCTINCREASE setting and monitoring segment growth, you can resolve the DB02018 error and prevent it from occurring in the future.
