Smart SAP Assistant

• What is the cause and solution for SAP error message TW027 - No more space in the cursor buffer ?

  The SAP error message TW027 "No more space in the cursor buffer" typically occurs when the cursor buffer, which is used to store the results of database queries, has reached its maximum capacity. This can happen in scenarios where large datasets are being processed or when there are many open cursors in the system.
  Causes:
  
  Large Result Sets: When a query returns a large number of records, it can fill up the cursor buffer quickly.
  Too Many Open Cursors: If there are multiple database connections or transactions that are not being closed properly, it can lead to exhaustion of the cursor buffer.
  Configuration Limits: The default configuration settings for the cursor buffer may not be sufficient for the workload being processed.
  
  Solutions:
  
  Optimize Queries: Review and optimize the SQL queries to ensure they are not returning more data than necessary. Use filters to limit the result set size.
  Close Unused Cursors: Ensure that all database cursors are properly closed after their use. This can be done by reviewing the application code or ABAP programs.
  Increase Cursor Buffer Size: If the application requires handling large datasets, consider increasing the size of the cursor buffer. This can be done by adjusting the relevant parameters in the SAP system configuration.
  Batch Processing: If applicable, implement batch processing to handle large datasets in smaller chunks rather than all at once.
  Monitor and Analyze: Use transaction codes like ST04 (Database Performance Analysis) or ST05 (SQL Trace) to monitor database performance and identify any long-running queries or excessive cursor usage.
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to cursor buffer issues for specific patches or recommendations. You can search the SAP Support Portal for relevant notes.
  Database Configuration: Depending on the database being used (e.g., Oracle, SQL Server, HANA), there may be specific configurations or parameters that can be adjusted to improve cursor handling.
  Performance Tuning: Regularly perform performance tuning and monitoring to ensure that the database and application are running efficiently.
