Problem using UTL_FILE (difference script/procedure)

[efrijters]

Hello.
I have a problem with the following script:

DECLARE
fid UTL_FILE.FILE_TYPE;
v VARCHAR2(32767);

PROCEDURE recNgo (str IN VARCHAR2)
IS
BEGIN
DBMS_OUTPUT.PUT_LINE ('UTL_FILE error ' || str);

UTL_FILE.FCLOSE (fid);
END;
BEGIN
/* Change the directory name to one to which you at least
|| THINK you have read/write access.
*/
fid := UTL_FILE.FOPEN ('c:\temp', 'source.txt', 'R');
UTL_FILE.GET_LINE (fid, v);
dbms_output.put_line (v);
UTL_FILE.FCLOSE (fid);

fid := UTL_FILE.FOPEN ('c:\temp', 'destin.txt', 'W');
UTL_FILE.PUT_LINE (fid, v);
UTL_FILE.FCLOSE (fid);
EXCEPTION
WHEN UTL_FILE.INVALID_PATH
THEN recNgo ('invalid_path');
WHEN UTL_FILE.INVALID_MODE
THEN recNgo ('invalid_mode');
WHEN UTL_FILE.INVALID_FILEHANDLE
THEN recNgo ('invalid_filehandle');
WHEN UTL_FILE.INVALID_OPERATION
THEN recNgo ('invalid_operation');
WHEN UTL_FILE.READ_ERROR
THEN recNgo ('read_error');
WHEN UTL_FILE.WRITE_ERROR
THEN recNgo ('write_error');
WHEN UTL_FILE.INTERNAL_ERROR
THEN recNgo ('internal_error');
END;
/

(it copies the data from an existing source.txt to destin.txt in the c:\temp directory on the server)

Problem: If I save this script into a file ('utltest.sql') and I run it from SQLPLUS: @utltest; then the script runs without errors and does what it suppose to. GREAT!
BUT: if I transform this script into a stored procedure and I start it, it generates the exception UTL_FILE.INVALID_PATH. I trace it via TOAD.

Oracle version: 8.1.7.1.1
The init.ora contains the UTL_FILE_DIR-parameter with the single directory: c:\temp (no quotes)


The procedure:
CREATE OR REPLACE PROCEDURE copy_server_file
IS
--DECLARE
fid SYS.UTL_FILE.FILE_TYPE;
v VARCHAR2(32767);

PROCEDURE recNgo (str IN VARCHAR2)
IS
BEGIN
DBMS_OUTPUT.PUT_LINE ('UTL_FILE error ' || str);

UTL_FILE.FCLOSE (fid);
END;
BEGIN
/* Change the directory name to one to which you at least
|| THINK you have read/write access.
*/
fid := UTL_FILE.FOPEN ('c:\temp', 'source.txt', 'R');
UTL_FILE.GET_LINE (fid, v);
dbms_output.put_line (v);
UTL_FILE.FCLOSE (fid);

fid := UTL_FILE.FOPEN ('c:\temp', 'destin.txt', 'W');
UTL_FILE.PUT_LINE (fid, v);
UTL_FILE.FCLOSE (fid);
EXCEPTION
WHEN UTL_FILE.INVALID_PATH
THEN recNgo ('invalid_path');
WHEN UTL_FILE.INVALID_MODE
THEN recNgo ('invalid_mode');
WHEN UTL_FILE.INVALID_FILEHANDLE
THEN recNgo ('invalid_filehandle');
WHEN UTL_FILE.INVALID_OPERATION
THEN recNgo ('invalid_operation');
WHEN UTL_FILE.READ_ERROR
THEN recNgo ('read_error');
WHEN UTL_FILE.WRITE_ERROR
THEN recNgo ('write_error');
WHEN UTL_FILE.INTERNAL_ERROR
THEN recNgo ('internal_error');
END;

Thanks in advance!

UTL_FILE.FOPEN ('c:\temp', 'source.txt', 'R');
change the 'c:\temp' to 'c:\temp\'
