  Causes of S_ORA_MON112
  
  
  Cursor Management Issues: The error often indicates that an application is trying to use a database cursor that has been closed or is no longer valid. This can happen if:
  
  The cursor was explicitly closed in the application code.
  The session that created the cursor has been terminated.

  Database Connection Problems: If there are intermittent connectivity issues between the SAP application and the Oracle database, it can lead to invalid cursor states.
  
  
  Resource Limits: The database may have reached its limit for open cursors, which can prevent new cursors from being opened or existing ones from being used.
  
  
  Transaction Management: If a transaction is not properly managed (e.g., not committed or rolled back), it can lead to invalid cursor states.
  
  
  Code Bugs: There may be bugs in the ABAP code or SQL statements that lead to improper handling of cursors.
