Comment accorder l'accès aux vues v$ (v$session, v$instance)

On ne peut pas accorder un accès direct à V$session car v$session est un synonyme. Il en va de même pour v$instance

En fait, cela est vrai pour toutes les vues v$ car elles sont toutes synonymes

SQL> GRANT SELECT ON v$session TO test_user;
grant select on v$session to test_user
*
ERROR at line 1:
ORA-02030: can only select from fixed tables/views

SQL> GRANT SELECT ON v$instance TO test_user;
grant select on v$instance to test_user
*
ERROR at line 1:
ORA-02030: can only select from fixed tables/views

Requête pour montrer que V$SESSION est un synonyme public

SQL> SELECT owner, object_type FROM dba_objects WHERE object_name = ‘V$SESSION’;
OWNER OBJECT_TYPE
———————— ——————-
PUBLIC SYNONYM

SQL> SELECT owner, object_type FROM dba_objects WHERE object_name = ‘V$INSTANCE’; 
OWNER OBJECT_TYPE 
———————— ——————- 
PUBLIC SYNONYM

Requête pour afficher l'objet (table/vue) vers lequel pointe le synonyme

SQL> select table_owner, table_name FROM dba_synonyms where synonym_name = ‘V$SESSION’;
TABLE_OWNER TABLE_NAME
————– ——————————
SYS V_$SESSION

SQL> select table_owner, table_name FROM dba_synonyms where synonym_name = ‘V$SESSION’; 
TABLE_OWNER TABLE_NAME 
————– —————————— 
SYS V_$INSTANCE

Comment accorder l'accès aux vues v$

Nous pouvons accorder l'accès  à ces vues   en accordant  l'accès accordé à la table/vue sous-jacente.
donc pour V$session, nous devons accorder select sur v_$session. De même pour les autres vues, nous devons faire la même chose

SQL> GRANT SELECT ON V_$SESSION TO test_user;
Grant succeeded.

SQL> GRANT SELECT ON V_$INSTANCE TO test_user; 
Grant succeeded.

Remarque :Les mêmes étapes peuvent être utilisées pour trouver d'autres vues V$ et l'accès peut être accordé en fonction de la représentation interne

Voici quelques-unes des vues v$ avec le nom de synonyme et le nom de table. nous devons utiliser la table pour accorder l'accès à l'utilisateur, si nous essayons avec un nom de synonyme, nous obtiendrons le même échec pour toutes ces vues
