ORA-904 when calling a sys package from a private one (on 9.2.0.5.0)

Question

Hi,
I explain:
SELECT DBMS_PIPE.UNIQUE_SESSION_NAME
FROM dual;
works!!!
CREATE OR REPLACE FUNCTION GET_NAME RETURN VARCHAR2 IS
vc_name VARCHAR2(1000);
BEGIN
SELECT DBMS_PIPE.UNIQUE_SESSION_NAME
INTO vc_name
FROM dual;
RETURN vc_name;
END GET_NAME;
works (no error at compile time)
BUT:
SELECT GET_NAME FROM DUAL;
Get a ORA-00904 error:
ORA-00904: : identificateur non valide
ORA-06512: at "DBASYS.GET_NAME", line 4
This mean that DBMS_PIPE.UNIQUE_SESSION_NAME
is unknown.
But I used it from the same session just before.
What is the problem ?
This example is simple, I HAVE TO use a function, in my true function, I do things before and after the call.
Thanks.

Hi Kamal,
Thank you for taking care of my problem...
About:
CREATE OR REPLACE FUNCTION GET_NAME RETURN VARCHAR2 IS
vc_name VARCHAR2(1000);
BEGIN
vc_name := DBMS_PIPE.UNIQUE_SESSION_NAME;
RETURN(vc_name);
END GET_NAME;
I can not even compile it, I get PLS-00021 DBMS_PIPE UNKNOWN (the message is in french so my translation could differ of the real oracle message but code is OK)
I think that this is the problem of GRANTed objects. It seems that even if my account is DBA, my procs does not inherit of the 'public' grants and that the real owner of the object should GRANT to me the EXECUTE.
If this is the problem, I do not have the SYS password to do the GRANT.
Do you think there could be a work around?
Thanks again,
Christian COMMARMOND
