oracle10g 审计的配置

SQL> conn / as sysdba;
SQL> show parameter audit;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
audit_file_dest string /u01/app/oracle/admin/ORCL/adump
audit_sys_operations boolean FALSE
audit_syslog_level string
audit_trail string NONE

#####//SQL> alter system set audit_sys_operations=TRUE scope=spfile; --审计管理用户(以sysdba/sysoper角色登陆)
SQL> alter system set audit_trail=db,extended scope=spfile;
SQL> startup force;
SQL> show parameter audit;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
audit_file_dest string /u01/app/oracle/admin/ORCL/adump
audit_sys_operations boolean TRUE
audit_syslog_level string
audit_trail string DB, EXTENDED

########开始审计

SQL> conn / as sysdba
SQL> audit update table,insert table by pdm9;
我这么执行：SQL> AUDIT ALTER, AUDIT, COMMENT, DELETE, FLASHBACK, GRANT, INDEX, INSERT, LOCK, RENAME, SELECT, UPDATE ON SYSTEM.NBSTUTB BY ACCESS WHENEVER SUCCESSFUL；
我需要的审计内容：SELECT "TIMESTAMP", "USERNAME", "USERHOST", "TERMINAL", "ACTION_NAME", "OWNER", "OBJ_NAME", "EXTENDED_TIMESTAMP", "SQL_TEXT" FROM "SYS"."DBA_AUDIT_OBJECT" ;
SQL> startup force;

##查看审计
SQL> select OS_USERNAME,username,USERHOST,TERMINAL,TIMESTAMP,OWNER,obj_name,ACTION_NAME,sessionid,os_process,sql_text from dba_audit_trail;

##关闭审计
SQL>alter system set audit_trail='FALSE' scope=spfile;
SQL> startup force;
