Connect problem with db link and scheduler_jobs on 10.2.0.4.0

Question

hello guys
i have got this problem, i hope someone can help me to understand and solve it.
I have a pl/sql procedure where is referenced a table on a db_link. I own all the grants needed, and if i recall it in an anonymous block, it seems to work.
i.e
create or replace procedure routine_1 is
v_app varchar2(1);
begin
select 'x'
into v_app
from other_user.some_table@my_db_link
where rownum<2;
end routine_1;
Instead, while recalling it from a job scheduled with dba_scheduler package, with the same user, while opening the cursor where the db link table is referenced, i got a connect error:
ORA-01017: invalid username/password; logon denied
ORA-02063: preceding line from xxxxxx (where xxxxxx is the db link)
i would like to understand where i am mistaking. I already checked the user for the connection in the scheduled job and is the same of the anonymous block call.
thanks in advance
Claudio

hello dracis
thanks for the new answer.
i have not access to metalink. Anyway, oracle version is 10g not 11.
Anyway, about dbms_job package (Scheduler is the newer version of dbms_job), i found a phrase on a site saying this:
"Jobs that reference database links will fail if the database link is not fully qualified with the username and password. This is another subtle consequence of the execution environment of jobs."
Probably the cause is that the db link, to work, must be owned by the same user that owns the procedure where is referenced. In this way we hope ownername and password are in some way accessible.
We are trying to check this solution, but we have to wait for some grants.
