详解Oracle如何解锁用户的方法

希望本文对大家有所帮助。1. 安装时选择的自动安装,由于时间久远忘记用户名、密码了,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,终于在试了下dbsnmp/dbsnmp,提示被锁;2. 在CMD中启动SQLPLUS;用sqlplus/as sysdba登录源码天空,Oracle如何解锁用户提示连接到:Oracle Database 10g Express Edition Release 10.2.0.1.0 - Production3. 执行ALTER USER DBSNMP ACCOUNT UNLOCK;4. 从新用SQL/PLUS登录,设置用户名、密码;注:由于刚才解锁的用户名是DBSNMP,所以这里设置的用户名也是DBSNMP

怎样给oracle数据库的用户解锁

1、找到并进入运行窗口:(可以用windows+r快捷键哦)输入sqlplus命令:如图

2、进入新窗口后使用scott/tiger用户和密码进行登录会发现登录不成功:如图

3、这时我们可以使用system用户进行登录,应为此用户的权限排第二,并且密码我们已经在安装时输入了了,所以是可以登录进入的:如图

4、system登录成功之后就可以使用命令给用户进行解锁了:如图

5、最后再用scott/tiger用户时,你可以神奇的发现此时能连接成功了:如图

Oracle账号被锁定如何解锁

1、查看环境变量ORACLE_SID的设置情况:

windows:

echo

%ORACLE_SID%

linux:

echo

$ORACLE_SID

2、

设置环境变量ORACLE_SID的值为你想登录的oracle实例的SID:

set

ORACLE_SID=orcl

键入命令:sqlplus

/

as

sysdba

就可以以sysdba的身份登录到oracle了!

linux系统下,如果找不到sqlplus命令的话,请切换到oracle用户。

在sqlplus窗口执行命令:

alter

user

you_username

identified

by

you_password;

就可以修改你的用户的密码了~

如果此时用户被锁定,没关系:

既然是被锁住了,那就通过解锁system用户。

SQL

alter

user

system

account

unlock;

User

altered.

SQL

select

username,account_status

from

dba_users

where

username='SYSTEM';

USERNAME

ACCOUNT_STATUS

----------

--------------------------------

SYSTEM

OPEN

SQL
