Oracle Error Message
LFI-00133: Trying to create file string that already exists.
Reason for the Error
The file object was initialized with LFILOPTY_OUTPUT and without LFILOPTY_REPLACE and yet a file by this name already exists.
Solution
Check to make sure that you are creating the right file. If you intend to overwrite the file if it exists that specify the replace option LFILOPTY_REPLACE when initializing the file object.
