Getting Error "ORA-22288: file or LOB operation FILEOPEN failed"

Hi,

I created a DB directory TEST_DIR_KR using the below command

create or replace directory TEST_DIR_KR AS '/home/applmgr/krishna';

I excecuted the below piece of code.

declare

l_clob clob;

l_bfile bfile;

begin

l_bfile := bfilename('TEST_DIR_KR','a.txt');

dbms_lob.fileopen(l_bfile);

dbms_lob.fileclose(l_bfile);

end;

I get the following error when the above piece of code is executed:

Error report -

ORA-22288: file or LOB operation FILEOPEN failed

No such file or directory

ORA-06512: at "SYS.DBMS_LOB", line 805
