oracle資料庫system表空間增長過大的問題

網上些解決方法，就是關閉審計，之前也有同事推薦這樣，下麵就是關閉審計的步驟。

VALUE=DB即審計開啟，改成FALSE即可。

SQL> show parameter audit_trail;

NAME                     TYPE     VALUE
------------------------------------ ----------- ------------------------------
audit_trail                 string     DB
SQL> alter system set audit_trail=FALSE scope=spfile;

System altered.

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
ORACLE instance started.

SQL> show parameter audit_trail;

NAME                     TYPE     VALUE
------------------------------------ ----------- ------------------------------
audit_trail                 string     FALSE
SQL> 

有時還需要將另一個參數修改 

audit_sys_operations 如果這個參數值不是false，則需要修改成false

alter  system  set audit_sys_operations=FALSE  scope=spfile;

SQL> show  parameter  audit; 

NAME                     TYPE     VALUE
------------------------------------ ----------- ------------------------------
audit_file_dest              string     /u01/app/oracle/admin/oadb/adu
                         mp
audit_sys_operations             boolean     FALSE
audit_syslog_level             string
audit_trail                 string     FALSE
