• What is the cause and solution for SAP error message 00960 - DB error: Cursor is no longer available ?

  The SAP error message "00960 DB error: Cursor is no longer available" typically indicates that there is an issue with the database cursor that is being used in a database operation. This error can occur in various scenarios, often related to database connectivity or transaction management. Here are some potential causes, solutions, and related information:
  Causes:
  
  Database Connection Issues: The connection to the database may have been lost or interrupted, causing the cursor to become invalid.
  Transaction Management: If a transaction is rolled back or committed, any cursors associated with that transaction may no longer be valid.
  Timeouts: Long-running queries may exceed the timeout settings, leading to the cursor being closed by the database.
  Resource Limits: The database may have reached its limit for open cursors, causing new requests to fail.
  Application Logic Errors: There may be issues in the application code that improperly manage the lifecycle of database cursors.
  
  Solutions:
  
  Check Database Connection: Ensure that the connection to the database is stable and that there are no network issues.
  Review Transaction Handling: Make sure that transactions are being properly managed. Avoid committing or rolling back transactions while cursors are still in use.
  Increase Timeout Settings: If timeouts are an issue, consider increasing the timeout settings for database connections and queries.
  Monitor Resource Usage: Check the database for open cursors and resource limits. You may need to increase the limit or optimize the application to use fewer cursors.
  Debug Application Code: Review the application code for proper cursor management. Ensure that cursors are opened, used, and closed correctly.
  Database Logs: Check the database logs for any additional error messages or warnings that could provide more context about the issue.
