Error reading a file using UTL_FILE - plsql

Question

I am facing some issue in reading a file using utl_file.
The same code is working fine in some of the instances and failing in one instance.
Below is the issue:
Code:
procedure del_mul_tags(p_request_id in number)
is
fileID UTL_FILE.FILE_TYPE;
fileID1 UTL_FILE.FILE_TYPE;
line varchar2(32000);
l_dir varchar2(1000);
l_file varchar2(20);
l_file1 varchar2(20);
l_request_id number;
l_count number := 0;
l_count_t number :=0;
l_write boolean := TRUE;
cursor c_dir is
select substr(OUTFILE_NAME,1,instr(OUTFILE_NAME,'/',-1,1)-1),substr(OUTFILE_NAME,instr(OUTFILE_NAME,'/',-1,1)+1)
from fnd_concurrent_requests
where request_id = p_request_id;
begin
open c_dir;
fetch c_dir into l_dir,l_file;
close c_dir;
execute immediate 'create or replace directory W2_OUT_DIR as ''' || l_dir || '''';
begin
fileID1 := UTL_FILE.FOPEN ('W2_OUT_DIR', l_file, 'R'); -----Getting the error right here!!!-----------
loop
begin
UTL_FILE.GET_LINE (fileID1, line);
--Some Logic
EXCEPTION WHEN NO_DATA_FOUND THEN
UTL_FILE.FCLOSE(fileID1);
EXIT;
end;
end loop;
fileID := UTL_FILE.FOPEN ('W2_OUT_DIR', l_file, 'R');
loop
begin
UTL_FILE.GET_LINE (fileID, line);
--Some Logic
EXCEPTION WHEN NO_DATA_FOUND THEN
UTL_FILE.FCLOSE(fileID);
EXIT;
end;
end loop;
end;
EXCEPTION WHEN OTHERS THEN
fnd_file.put_line(fnd_file.log,'Error while deleting the xml tags: '||SQLERRM);
end;
................
In this instance file, l_file 'ACHAKR01.23067873' was created through another concurrent process. Its OS user is 'appsofde'.
And the unix permissions are as below:
-rw-r--r-- 1 appsofde dba 192092429 jan 27 05:00 ACHAKR01.23067873
The directory W2_OUT_DIR is created and the oracle user apps has EXECUTE,READ,WRITE privileges.
The file exists and the W2_OUT_DIR dir patch is correct.
Exact error coming is:
Error while deleting the xml tags: ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 536
ORA-29283: invalid file operation
Any thoughts here?

You will want to make sure the filesystem is presented to your Oracle DB host (not just your application server). I'm assuming it is otherwise you would get an invalid directory path error instead. I would suggest you double check however and also ensure the oracle account on the DB host has access to read the file in question. The account appsofde sounds as if its likely the application account.
