要在Oracle中啟用審計功能,您可以按照以下步驟操作:
1、使用sysdba權限登錄到Oracle數據庫。
2、運行以下命令啟用標準審計功能:
```
SQL> ALTER SYSTEM SET AUDIT_TRAIL=DB SCOPE=SPFILE;
SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP;
```
3、運行以下命令啟用審計功能:
```
SQL> AUDIT SELECT TABLE, INSERT TABLE, UPDATE TABLE, DELETE TABLE BY ACCESS;
SQL> AUDIT SELECT TABLE, INSERT TABLE, UPDATE TABLE, DELETE TABLE BY SESSION;
```
4、運行以下命令啟用審計功能:
```
SQL> AUDIT DROP ANY TABLE BY ACCESS;
SQL> AUDIT CREATE ANY TABLE BY ACCESS;
SQL> AUDIT ALTER ANY TABLE BY ACCESS;
SQL> AUDIT DROP ANY PROCEDURE BY ACCESS;
SQL> AUDIT CREATE ANY PROCEDURE BY ACCESS;
SQL> AUDIT ALTER ANY PROCEDURE BY ACCESS;
```
5、在需要審計的表上設置審計功能:
```
SQL> AUDIT SELECT, INSERT, UPDATE, DELETE ON
```
6、重新啟動數據庫以使更改生效。
請注意,啟用審計功能可能會對系統性能產生一定影響,因此建議在必要時才啟用審計功能。
