Man kann keinen direkten Zugriff auf V$session gewähren, da v$session ein Synonym ist. Dasselbe gilt für v$instance
Tatsächlich gilt dies für alle v$-Ansichten, da sie alle Synonyme sind
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
Die Abfrage zeigt, dass V$SESSION ein öffentliches Synonym ist
SQL> SELECT owner, object_type FROM dba_objects WHERE object_name = ‘V$SESSION’; OWNER OBJECT_TYPE ———————— ——————- PUBLIC SYNONYM SQL> SELECT owner, object_type FROM dba_objects WHERE object_name = ‘V$INSTANCE’; OWNER OBJECT_TYPE ———————— ——————- PUBLIC SYNONYM
Abfrage nach zeigt das Objekt (Tabelle/Ansicht), auf das das Synonym zeigt
SQL> select table_owner, table_name FROM dba_synonyms where synonym_name = ‘V$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_$INSTANCE
So gewähren Sie Zugriff auf v$-Ansichten
Wir können Zugriff auf diese Ansichten gewähren, indem wir Zugriff auf die zugrunde liegende Tabelle/Ansicht erteilen.
Also müssen wir für V$session eine Auswahl von v_$session gewähren. In ähnlicher Weise müssen wir für andere Ansichten dasselbe tun
SQL> GRANT SELECT ON V_$SESSION TO test_user; Grant succeeded. SQL> GRANT SELECT ON V_$INSTANCE TO test_user; Grant succeeded.
Hinweis:Die gleichen Schritte können verwendet werden, um andere V$-Ansichten zu finden, und der Zugriff kann abhängig von der internen Darstellung gewährt werden
Hier sind einige der v$-Ansichten mit dem Synonymnamen und dem Tabellennamen. Wir müssen die Tabelle verwenden, um dem Benutzer Zugriff zu gewähren. Wenn wir es mit dem Synonymnamen versuchen, erhalten wir denselben Fehler für alle diese Ansichten

Ich hoffe, Ihnen gefällt der kurze Artikel über Grant Select auf v_$session. Dasselbe kann ausgeführt werden, um Zugriff auf beliebige v$views zu gewähren. Ich hoffe, Ihnen gefällt dieser Beitrag. Bitte geben Sie Feedback
