Oracle 11g忘記SYS和SYSTEM密碼的處理辦法

Oracle 11g忘記SYS和SYSTEM密碼怎麼辦，答案很簡單：修改密碼！

1.首先使用作業系統方式認證登陸SYS賬戶，修改SYSTEM賬戶密碼。

$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.4.0 Production on Fri Mar 20 14:23:41 2015

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
 With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,
 Data Mining and Real Application Testing options
 
 SQL> show user;
 USER is "SYS"
 SQL> alter user SYSTEM identified by "oracle123";
 
 User altered.
 

 SQL> exit

2.使用SQLPLUS遠程登入方式登陸SYSTEM賬戶，修改SYS賬戶密碼。

$ sqlplus SYSTEM@orcl

SQL*Plus: Release 11.2.0.4.0 Production on Fri Mar 20 14:22:35 2015

至此，大功告成，使用遠程登入方式盡情登陸吧~
