Oracle 10G 默认用户名密码及解锁

很久没有使用sqlplus创建表空间和用户了，需要的时候竟然忘记了密码，试了好多次都没连接上，进而用户也被锁定，在网上找了一些资料，问题解决了，希望对和我一样情况的朋友们有所帮助。

　　1.安装时选择的自动安装，忘了用户名和密码导致现在试了几个默认的用户名密码後（表格中附带默认用户名及密码），都提示无效的用户名、密码，

　　这时候要找到一组用户名、密码提示被锁，才能进行下一步

安装ORACLE时，若没有为下列用户重设密码，则其默认密码如下：

用户名/密码                                                登录身份                                                  说明

 

sys/change_on_install                   SYSDBA或SYSOPER            不能以NORMAL登录，可作为默认的系统管理员

system/manager                             SYSDBA或NORMAL              不能以SYSOPER登录，可作为默认的系统管理员

sysman/oem_temp                          sysman 为oms的用户名  

scott/tiger                                      NORMAL

普通用户

aqadm /aqadm                              SYSDBA或NORMAL

高级队列管理员

Dbsnmp/dbsnmp                          SYSDBA或NORMAL                         复制管理员

　　2，在CMD中启动SQLPLUS；用sqlplus/as sysdba登录，提示

　　连接到:

　　Oracle Database 10g Express Edition Release 10.2.0.1.0 - Production

　　3.执行ALTER USER 你被锁的用户名 ACCOUNT UNLOCK；

　　4.重新用SQL/PLUS登录，用你刚刚解锁的用户名、密码；

　　重新修改密码就可以了！

　　具体操作如下：

　　1.运行->sqlplus /nolog

　　2.输入conn / as sysdba 管理员账户登录

　　3.如果用户被锁定先解锁：

　　alter user system account unlock;

　　4.修改密码：

　　alter user system identified by qiushun;

　　接下来可以用sqlplus登陆了。
