• What is the cause and solution for SAP error message DB6140 - Table &1 has more than &2 percent of overflow page accesses ?

  The SAP error message DB6140 indicates that a specific database table (denoted as &1) is experiencing a high percentage of overflow page accesses, exceeding a threshold of &2 percent. This situation typically arises when the table's data is not efficiently organized, leading to performance issues due to excessive use of overflow pages.
  Cause:
  
  Table Structure: The table may have a structure that leads to frequent updates or inserts, causing data to overflow from the main data pages to overflow pages.
  Data Growth: The volume of data in the table may have grown significantly, leading to more frequent use of overflow pages.
  Inadequate Page Size: The page size may not be optimal for the data being stored, leading to more overflow pages.
  Fragmentation: Over time, as records are added and deleted, the table can become fragmented, leading to inefficient data storage and access patterns.
  
  Solution:
  
  Reorganize the Table: Use the database tools to reorganize or rebuild the table. This can help to compact the data and reduce the number of overflow pages.
  Increase Page Size: If applicable, consider increasing the page size for the table to accommodate larger records and reduce the likelihood of overflow.
  Data Archiving: If the table contains historical data that is no longer needed for daily operations, consider archiving old records to reduce the size of the table.
  Index Optimization: Review and optimize the indexes on the table. Proper indexing can improve access patterns and reduce the need for overflow pages.
  Monitor and Analyze: Continuously monitor the table's performance and access patterns. Use database performance analysis tools to identify and address issues proactively.
  
  Related Information:
  
  Database Administration: Consult your database administrator for specific tools and commands available for your database system (e.g., SAP HANA, Oracle, SQL Server) to reorganize tables and manage page sizes.
