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

1.首先使用操作系統方式認證登陸SYS賬戶，修改SYSTEM賬戶密碼。

$ sqlplus / as sysdbaSQL*Plus: Release 11.2.0.4.0 Production on Fri Mar 20 14:23:41 2015Copyright (c) 1982, 2013, Oracle. All rights reserved.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> exit2.使用SQLPLUS遠程登錄方式登陸SYSTEM賬戶，修改SYS賬戶密碼。$ sqlplus SYSTEM@orclSQL*Plus: Release 11.2.0.4.0 Production on Fri Mar 20 14:22:35 2015Copyright (c) 1982, 2013, Oracle. All rights reserved.Enter password: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 "SYSTEM" SQL> alter user SYS identified by "Oracle123"; User altered. SQL> exit

至此，大功告成，使用遠程登錄方式盡情登陸吧~
