oracle11g中默认在default概要文件中设置了"FAILED_LOGIN_ATTEMPTS=10次"，当输入密码错误次数达到设置值将导致此，该用户会自动锁住。

1. 登陆oracle(管理员)  
普通用户：sqlplus username/password;
管理员：sqlplus sys/manager as sysdba;

2. 查询被锁用户
SQL> select username, account_status from dba_users where username='xxx';

3. 解锁用户
SQL> alter user xxx account unlock;

4. 查看用户限制登陆次数
SQL> select * from dba_profiles where RESOURCE_NAME='FAILED_LOGIN_ATTEMPTS';

5. 修改用户无论输入多少次都不会被锁定
SQL> alter profile default limit failed_login_attempts unlimited;
