Oracle Error LFI-00118: Unable to change type to Unknown.

Oracle Error Message

LFI-00118: Unable to change type to Unknown.

Reason for the Error

The function lfichty() was called to change the file extension to LFIEXUNK (Unknown). This is not a valid operation.

Solution

Check why you are doing this. If the extension is already unknown then you do not need to do this. If you just want no extension then use the extension type LFIEXNONE.
