导致出现改错误的原因是:在oracle database 11g中,默认在default概要文件中设置了“FAILED_LOGIN_ATTEMPTS=10”,当输入密码错误次数达到设置值将导致此问题。
select username,profile from dba_users;
select * from dba_profiles where profile='DEFAULT' and resource_name='FAILED_LOGIN_ATTEMPTS';
alter profile default limit failed_login_attempts unlimited;
alter user nctestNC65 account unlock;
