sqlplus登录Oracle时ORA-01017: invalid username/password; logon denied的错误
今天用scott用户登录Oracle数 据库时,竟然出现了ORA-01017: invalid username/password; logon denied错误,原以为是因为我的scott用户没有解锁,后用system用户登录,然后用alter user scott account unlock语句对scott用户进行解锁,可是解锁后依然不能进入,还是报告ORA-01017: invalid username/password; logon denied错误,仔细想了一会,感觉应该是我在对scott用户解锁时没有设置密码,所以不论输入什么密码都是错误的,于是我想到了如下的解决办法,为 防止以后犯此类错误,现将错误及解决方式记录于下:
SQL*Plus: Release 11.2.0.1.0 Production on 星期五 10月 12 20:03:09 2012

请输入用户名: scott
输入口令:
ERROR:

请输入用户名: system
输入口令:
连接到:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> conn /as sysdba;
已连接。
SQL> alter user SCOTT account unlock identified by Orcl123456;
用户已更改。
SQL> select username,account_status from dba_users where username='SCOTT';
USERNAME
------------------------------------------------------------
ACCOUNT_STATUS
----------------------------------------------------------------
SCOTT
OPEN
SQL> conn scott/Orcl123456
已连接。
到此就可以用scott用户正常登陆了,如不放心还可以使用一下的查询语句进行验证:
SQL> select * from emp;
