Insert file in db column

Question

Hi all
i'm not very experienced in p-sql so i have an answer.
Scenario: Open VMS System with Oracle 9
Problem : i want to insert a text file in the db by calling a procedure from Pro Cobol
I see that is possible to pass the url and read the file with dbms, but i don't understand, after i read the file, how i can insert it.
Any suggestion?

Does this file reside on a file server or does this file is transmitted by the calling procedure with a CLOB datatype (i don't speak about the name, but the content :-)) ?The file is transmitted by the calling procedure, the problem is that i can only pass the file path because i haven't a file object or similar.
Another solution can be to use SQL*Loader to load the files OR if you simply want to give an access to a file to a PL/SQL program you also have the option to use BFILE: but in this last solution file are not stored inside the DB (it's only a 'reference' or let's say a pointer to this file) : It depends on your need: what will you do once the file file be accessible/loaded in the DB?So, i have this Pro Cobol program that create some files that will be inserted into db, then a Java-Client application read this blob and show it in a pdf format.
How many file did you plan to use? Is it something done one time or is it something done "on demand" by a user for example? ...Are about 1000 files one time at week, and are inserted at the end of users operation so the procedure can be called many times.
i see the link and i think i can use one of this solution:
create or replace procedure insert_test(test_id in integer, filename in varchar) IS
l_bfile bfile;
begin
l_bfile := bfilename('MNT_TEST', filename);
insert into bfile_test (id, bfile_data) values (test_id, l_bfile);
end;
OR
create or replace procedure insert_test(test_id in integer, filename in varchar) IS
declare
l_blob blob;
l_bfile bfile;
begin
insert into demo values ( 1, empty_blob() )
returning theBlob into l_blob;
l_bfile := bfilename( 'MY_FILES', filename );
dbms_lob.fileopen( l_bfile );
dbms_lob.loadfromfile( l_blob, l_bfile,
dbms_lob.getlength( l_bfile ) );
dbms_lob.fileclose( l_bfile );
end;
I think the best is the secon,isn't it?
Can it be a good solution for me?
Another problem is that the database can't be on the same server of the ProCobol program but in another machine with different OS like Windows, how i can do in this case?
