Oracle Error Message
LFI-00134: Unable to protect a file for an append operation.
Reason for the Error
The LFILOPTY_APPEND and LFILOPTY_PROT options were both specified for the file. This is currently not allowed because it would require copying the entire file at open time.
Solution
Decide if you really need to protect the file for append. If so then think about making a copy of it before appending.
