• What is the cause and solution for SAP error message DB02123 - sort_are_retained_size. Size(KB) of post-sort PGA sort area. ?

  The SAP error message DB02123, which refers to "sort_area_retained_size," typically indicates an issue related to the size of the Post-Sort Program Global Area (PGA) sort area in the database. This error can occur when the sort area allocated for database operations is insufficient for the tasks being performed, leading to performance issues or failures in executing queries that require sorting.
  Cause:
  
  Insufficient Sort Area Size: The size of the sort area allocated for sorting operations is too small to handle the data being processed.
  High Volume of Data: Large datasets being sorted can exceed the allocated sort area size.
  Database Configuration: The database parameters related to memory allocation for sorting may not be optimally configured.
  Concurrent Operations: Multiple concurrent operations requiring sorting can lead to contention for the available sort area.
  
  Solution:
  
  
  Increase Sort Area Size:
  
  Adjust the database configuration parameters to increase the size of the sort area. This can typically be done by modifying the sort_area_size parameter in the database configuration.
  For example, in Oracle, you can increase the SORT_AREA_SIZE parameter.
  
  
  
  Optimize Queries:
  
  Review and optimize the SQL queries that are causing the error. Ensure that they are efficient and do not require excessive sorting.
  Use indexes where appropriate to reduce the need for sorting.
  
  
  
  Monitor and Tune Database Performance:
  
  Use database monitoring tools to analyze performance and identify bottlenecks.
  Tune other related parameters that may impact memory usage and sorting, such as pga_aggregate_target in Oracle.
  
  
  
  Check for Concurrent Load:
  
  If multiple users or processes are running queries that require sorting, consider scheduling heavy operations during off-peak hours or implementing resource management techniques.
  
  
  
  Consult Documentation:
  
  Refer to the specific database documentation for guidance on configuring memory parameters and optimizing performance.
  
  
  
  Related Information:
  
  Database Documentation: Check the documentation for your specific database (e.g., Oracle, SQL Server, etc.) for details on memory management and configuration parameters.
  SAP Notes: Look for relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Performance Tuning Guides: Consider reviewing performance tuning guides for your database to ensure optimal configuration and resource allocation.
  
  If the issue persists after making adjustments, it may be beneficial to consult with a database administrator or SAP support for further assistance.
