PL/SQL: ORA-01031: insufficient privileges

Question

Hi Guys,
I am trying to create a package, inside that package create a function.
I am getting error - PL/SQL: ORA-01031: insufficient privileges.
I have done -
1. Conn system/system@mydb
2. Grant select on system.v_db_name to <user>
3. Conn <user>/<pwd>@mydb
4. Create or Replace Function get_db_name Return VARCHAR2 IS
v_db_name1 VARCHAR2(100):= NULL;
BEGIN
Select instance_name into v_db_name1
from system.v_db_name
where rownum<2;
IF Lower(v_db_name1) = 'vdev9i' THEN
v_db_name1 := 'vd';
ELSIF Lower(v_db_name1) = 'vcal9i' THEN
v_db_name1 := 'vc';
ELSIF Lower(v_db_name1) = 'vlive9i' THEN
v_db_name1 := 'vl';
END IF; RETURN v_db_name1;
END;
I understand that privileges have to be given directly and not through role.
That is what i have done in first step, but still this error persists.
Can anyone please help in this?
Thanks!
Av.

Hi Mtichel,
Thanks for your feedback,
I have given explicit grants to User1 on sys.v_$instance as follows -
SQL> Conn sys/<pwd>@dbname as sysdba
SQL> grant select on sys.v_$instance to User1
SQL> Conn system/<pwd>@dbname
SQL> Grant select on system.v_db_name to User1
SQL> Conn User1/<pwd>@dbname
SQL> Select * from v_db_name - successfull
SQL>
1 create or replace Function get_db_name Return VARCHAR2 IS
2 v_db_name VARCHAR2(100):= NULL;
3 BEGIN
4 Select instance_name into v_db_name
5 from system.v_db_name
6 where rownum<2;
7 IF Lower(v_db_name) = 'vdev9i' THEN
8 v_db_name := 'vd';
9 ELSIF Lower(v_db_name) = 'vcal9i' THEN
10 v_db_name := 'vc';
11 ELSIF Lower(v_db_name) = 'vlive9i' THEN
12 v_db_name := 'vl';
13 END IF; RETURN v_db_name;
14* END;
