一、ORACLE 10g批量重新整理使用者密碼

select ' alter user ' || username ||' identified by values '''||password ||''';' from dba_users where ACCOUNT_STATUS<>'LOCK' and ACCOUNT_STATUS not like 'EXPIRED%LOCKED';

或者

select ' alter user ' || username || ' identified by values ''' || password || ''';' from dba_users where account_status='OPEN';

得到以下結果

AA
--------------------------------------------------------------------------------

alter user SYS identified by values '8A8F025737A9097A';
alter user SYSTEM identified by values '2D594E86F93B17A1';

分別執行以上結果中的SQL語句

SQL>alter user SYS identified by values '8A8F025737A9097A';

User altered.

SQL>alter user SYSTEM identified by values '2D594E86F93B17A1';

User altered.

二、ORACLE 11g重新整理使用者密碼

select ' alter user ' || name ||' identified by values '''||password ||''';' aa from sys.user$ where name in (select username from dba_users where ACCOUNT_STATUS<>'LOCK' and ACCOUNT_STATUS not like 'EXPIRED%LOCKED');

 或者

select ' alter user ' || name ||' identified by values '''||password ||''';' aa from sys.user$ where name in (select username from dba_users 

得到以下結果

AA
--------------------------------------------------------------------------------

alter user SYS identified by values '8A8F025737A9097A';
alter user SYSTEM identified by values '2D594E86F93B17A1';

分別執行以上結果中的SQL語句

SQL>alter user SYS identified by values '8A8F025737A9097A';

User altered.

SQL>alter user SYSTEM identified by values '2D594E86F93B17A1';

User altered.

以上方法不用修改使用者原有密碼，只是重新整理了使用者密碼的有效期期限。
