I am trying to create directory is SQL Developer and create a simple text file there using this code :
CREATE DIRECTORY ABC AS '/abc';
DECLARE
fileHandler UTL_FILE.FILE_TYPE;
BEGIN
fileHandler := UTL_FILE.FOPEN('ABC', 'test_file.txt', 'W');
UTL_FILE.PUTF(fileHandler, 'Writing to a file\n');
UTL_FILE.FCLOSE(fileHandler);
END;
But it ends up with that Error
29283. 00000 - "invalid file operation"
*Cause: An attempt was made to read from a file or directory that does
not exist, or file or directory access was denied by the
operating system.
*Action: Verify file and directory access privileges on the file system,
and if reading, verify that the file exists.
In SQL developer the directory variable is created and visible
So, my question is Does that piece of code suppose to create directory by itself or do i have to create it manually? (I don't have access to the servers file system)
It looks like GRANTS are missing.
To create a directory:
CREATE OR REPLACE DIRECTORY alias AS 'pathname';
Where:
alias is the name of the directory alias.
pathname is the physical directory path.
To Grant:
GRANT permission ON DIRECTORY alias TO {user | role | PUBLIC};
Where:
permission is one of the following:
READ for read-only access
WRITE for write-only access
ALL for read and write access
alias is the name of the directory alias.
user is a database user name.
Edit:
Directory Check:
SQL> SELECT DIRECTORY_NAME , DIRECTORY_PATH FROM DBA_DIRECTORIES WHERE DIRECTORY_NAME = 'BDUMP';
DIRECTORY_NAME DIRECTORY_PATH
------------------------------ ---------------
BDUMP /home/fil_test/
Change directory permission. By default it has only Read and execute permission for others.
terminal$ chmod 777 fil_test
Block:
DECLARE
fHandle UTL_FILE.FILE_TYPE;
BEGIN
fHandle := UTL_FILE.FOPEN ('BDUMP', 'test_file', 'w');
UTL_FILE.PUT (fHandle, 'This is the first line');
UTL_FILE.PUT (fHandle, 'This is the second line');
UTL_FILE.PUT_LINE (fHandle, 'This is the third line');
UTL_FILE.FCLOSE (fHandle);

END;

And i See the file created:
terminal$ ls -lrt test_file*

Hi guys IP am trying to use the utl_file package in PLSQL...
I have granted the user to create directory privilege and read and write privilege from sysdba...when I create a directory it says "directory created", but is physical harddrive local location no directory is created.
When I write a code to give output in file it gives some errors.
Code:
SQL> create or replace directory PLSQL as 'D:\PLSQL';
Directory created.
SQL>declare
2 fp utl_file.file_type;
3 begin
4 fp := utl_file.fopen('D:\PLSQL', 'Hello.txt','w');
5 utl_file.putf(fp,'HI THIS IS WRITTEN IN SQLPLUS');
6 utl_file.fclose(fp);
7 end;

ORA-06512: at "SYS.UTL_FILE", line 41
ORA-06512: at "SYS.UTL_FILE", line 478
ORA-06512: at line 4
if any solution help...
Two objections so far:
when you create a directory (an Oracle object), nothing is "automatically" created in filesystem. That directory (D:\PLSQL) has to exist, you have to create it manually (using e.g. Windows Explorer or Command Prompt or ...).
Note that directory usually resides on a database server. If D:\PLSQL is located on your own PC (while the database is elsewhere), it won't work. If you can't access the database server (because of lack of privileges), you'll have to talk to DBA to do it for you. Though, saying that you connected as sysdba, I presume that it shouldn't be a problem for you.
when referencing the directory in PL/SQL code, you have to use its name (PLSQL), not its path (D:\PLSQL):
fp := utl_file.fopen('PLSQL', 'Hello.txt','w');
I tested your code, works just fine (file is created in my directory).
1st create a logical directory using below syntax:
create directory logfile as 'D:\PLSQL';
and then refer the same in your code. Also please be sure you have read, write grant on this new logical directory.
GRANT READ,WRITE ON DIRECTORY logfile TO user_Name;
declare
2 fp utl_file.file_type;
3 begin
4 fp := utl_file.fopen(logfile , 'Hello.txt','w');
5 utl_file.putf(fp,'HI THIS IS WRITTEN IN SQLPLUS');
6 utl_file.fclose(fp);
7 end;

I'm trying to write a simple txt file using SQL in Toad. Below is the SQL
create or replace directory dir_temp as 'C:\Users\name\Desktop\';
declare
f utl_file.file_type;
begin
f := utl_file.fopen('DIR_TEMP', 'something.txt', 'w');
utl_file.fclose(f);
end;
/
This results into error:
ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 536
ORA-29283: invalid file operation
ORA-06512: at line 4
I've verified the grants for Oracle user on directory. It has all permissions.
Also, I'm able to create spool file in the same directory.
Directory should be created by SYS, and has to be located on the database server (OK, it can be elsewhere, but it usually isn't). If database isn't installed on your own computer but on some database server, then directory object points to a directory on the server, not your own PC.
If you do it properly, it works. I use 11gXE, installed on my laptop. Here's how:
Connected as SYS, I'm creating a directory and granting privileges to user (SCOTT) who will use it.
SQL> show user
USER is "SYS"
SQL> create or replace directory dir_temp as 'c:\users\littlefoot\desktop';
Directory created.
SQL> grant read, write on directory dir_temp to scott;
Grant succeeded.
Connect as Scott; reuse code you wrote:
SQL> connect scott/tiger
Connected.
SQL> declare
2 f utl_file.file_type;
3 begin
4 f := utl_file.fopen('DIR_TEMP', 'something.txt', 'w');
5 utl_file.fclose(f);
6 end;
7 /
PL/SQL procedure successfully completed.
Looks OK. Check whether the file was created:
SQL> $dir c:\users\littlefoot\desktop\*.txt
Volume in drive C is OSDisk
Volume Serial Number is 7635-F892
Directory of c:\users\littlefoot\desktop
05.03.2020. 19:25 0 something.txt
1 File(s) 0 bytes
0 Dir(s) 290.609.057.792 bytes free
SQL>
Right; the file is here (empty, though, but - it exists).
So, if you do it right, it works.
I 'am trying to read and write files using utl_file package remotely but the oracle server cant read and write on other pc ,so i make a shared path on '\\adel-pc\test', and i want to read and write on that path but i get this error when reading :

UTL_FILE.fclose(l_file);
END;
so my questions are:
could I write and read on the shared path or it cant be done using utl_file ?
why I am getting this error , knowing that I gave read & write permissions to that path.
I'd suggest you not to do it that way.
First of all, you're creating that procedure in SYS schema, which is - generally speaking - a bad idea. Leave SYS (and SYSTEM) alone; create your own user, grant it required privileges (CREATE SESSION, CREATE PROCEDURE and any other you might require), connect to it and then write code you want.
Why are you creating directories dynamically? That is a one-time job and should be done once, connected as SYS. Although you might have created those directories (it is a good idea to first DBMS_OUTPUT.PUT_LINE command you're about to execute, make sure it is correctly written and then actually run it), you did not grant READ nor WRITE privileges on them to anyone, so - nobody can use them but SYS and - as I've said above - don't use SYS for that.
Note that I'm not talking about operating system privileges, but Oracle ones, e.g.
grant read, write on directory some_dir to scott;
Finally, as of creating a directory on a computer that is not the database server: you should use UNC (Universal Naming Convention) and create a directory literally as \\adel-pc\test; it won't work if you map that directory on the server and use its drive letter.
As of the error itself, huh ... you posted several hundreds lines of code, it is little bit too much to debug just by looking at it, and we miss other objects you use. No idea, sorry.
finally the problem is solved ,the problem was in windows system privileges , I had to give full control permissions to the files ,so yes i can write and read on the shared path using utl_file .
I am using util_file.fopen to import a .txt file into a database. However, I do not want hardcode the directory. Is there a way save the current directory to a variable or log the path? That way I can create an oracle directory that is the current directory, and util_file.fopen will always open the .txt file that is in the directory that I am running my pl/sql from
I know that "HOST CD" will show me my current directory, but I have not been able to save it to a variable or log it
Thanks
Create multiple directory objects:
CREATE DIRECTORY DIRECTORY_1 AS '/some/path';
CREATE DIRECTORY DIRECTORY_2 AS '/some/other/path';
CREATE DIRECTORY DIRECTORY_3 AS '/yet/another/path';
Assign the name of the directory to a variable:
strDirectory_to_use := 'DIRECTORY_1';
Use the variable when opening a file:
-- References /some/path/filename.txt
aFile := UTL_FILE.FOPEN(strDirectory_to_use, 'filename.txt', 'r');
Change the variable to contain the name of a different directory object:
strDirectory_to_use := 'DIRECTORY_2';
Now when you use the variable in a call to UTL_FILE.FOPEN it will look at the directory pointed to by directory object DIRECTORY_2:
-- References /some/other/path/filename.txt
aFile := UTL_FILE.FOPEN(strDirectory_to_use, 'filename.txt', 'r');
Best of luck.
If you want to use current working directory you can create that directory dinamically. Problem is when multiple processes try to access your procedure.
If you can ensure that only one process is using procedure at same time you can do:
create or replace procedure (mypath varchar2) as
begin
execute immediate 'CREATE OR REPLACE DIRECTORY DIRECTORY_1 AS ' || mypath;
aFile := UTL_FILE.FOPEN(DIRECTORY_1, 'filename.txt', 'r');
end;
/
If you can't ensure that only one thread will call procedure at same time it gets tricky. You can try to lookup directory.
create or replace procedure (mypath varchar2) as
dirname varchar2;
begin
select DIRECTORY_NAME into dirname from dba_directories where DIRECTORY_PATH = mypath;
if (dirname is null) then
dirname := substr(replace(replace(replace(replace(dirname,'\',''),':',''),'/',''),'.',''),1,30);
execute immediate 'CREATE OR REPLACE ' || dirname || ' AS ' || mypath;
end if;
aFile := UTL_FILE.FOPEN(dirname, 'filename.txt', 'r');
end;

When i am searching for directories registered to UTL_DIR i am getting the following :
select value from v$parameter where name='utl_file_dir';
/usr/tmp, /usr/tmp, /oradata/hrtst/db/tech_st/11.2.0/appsutil/outbound/HRTS, /usr/tmp
Does this mean /usr/tmp is the directory for UTL_DIR ?
also i cannot search for /oradata/hrtst/db/tech_st/11.2.0/appsutil/outbound/HRTS through winscp or putty.
Also i created a directory like
create or replace directory MY_DIR as '/usr/tmp';
and then i tried to write in this folder :
DECLARE
fileHandler UTL_FILE.FILE_TYPE;
begin
fileHandler := UTL_FILE.FOPEN('MY_DIR', 'test_file.txt', 'W');
UTL_FILE.PUTF(fileHandler, 'Writing TO a file\n');
UTL_FILE.FCLOSE(fileHandler);
EXCEPTION
WHEN others THEN
raise_application_error(-20000, 'ERROR: Invalid PATH FOR file.');
END;
anonymous block completed
though this block got executed succesfuly but no file got created in the directory when i checked.
