在这里我们要介绍的是Oracle如何解锁用户的方法，对于Oracle如何解锁用户，一般我们都是试用默认密码来进行。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，Oracle如何解锁用户提示
连接到:
Oracle Database
3. 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
