Oracle Error Message
KUP-04027: file name check failed: string
Reason for the Error
The check of the filename failed. These checks are platform specific, but they can include verifying that there are no hard links in the file path, the file is not a soft link, the file specification includes a parent reference (“../” on Unix), or the file was modified between the time the check was made and the file was opened.
Solution
Use a file location that does not violate any of the checks.
