Answer 1

One of my standard answers (which will explain the use of Directory Objects)...
The UTL_FILE_DIR parameter has been deprecated by oracle in favour of direcory objects because of it's security problems.
The correct thing to do is to create a directory object e.g.:
CREATE OR REPLACE DIRECTORY mydir AS 'c:\myfiles';Note: This does not create the directory on the file system. You have to do that yourself and ensure that oracle has permission to read/write to that file system directory.
Then, grant permission to the users who require access e.g....
GRANT READ,WRITE ON DIRECTORY mydir TO myuser;Then use that directory object inside your FOPEN statement e.g.
fh := UTL_FILE.FOPEN('MYDIR', 'myfile.txt', 'r');Note: You MUST specify the directory object name in quotes and in UPPER case for this to work as it is a string that is referring to a database object name which will have been stored in uppercase by default.
