v $ sessionは同義語であるため、直接アクセスV$sessionを許可することはできません。同じことがv$instanceにも当てはまります
実際、これはすべてのv $ビューに当てはまり、それらはすべて同義語です
SQL> GRANT SELECT ON v$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$instance to test_user * ERROR at line 1: ORA-02030: can only select from fixed tables/views
V$SESSIONがパブリックシノニムであることを示すクエリ
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
同義語が指すオブジェクト（テーブル/ビュー）を表示するためのクエリ
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
v$ビューへのアクセスを許可する方法
基になるテーブル/ビューへのアクセスを許可することで、これらのビューへのアクセスを許可できます。
したがって、V $ sessionの場合、v_$sessionでgrantselectを実行する必要があります。他のビューについても同様に、同じことを行う必要があります
SQL> GRANT SELECT ON V_$SESSION TO test_user; Grant succeeded. SQL> GRANT SELECT ON V_$INSTANCE TO test_user; Grant succeeded.
注：同じ手順を使用して他のV $ビューを検索し、内部表現に応じてアクセスを許可できます
シノニム名とテーブル名を持つv$ビューの一部を次に示します。ユーザーにアクセスを許可するためにテーブルを使用する必要があります。同義語名を使用しようとすると、これらすべてのビューで同じ失敗が発生します
