Question

oracle 11 ora-28000:the account is locked

登录用户名是system

Answer 1

账户被锁了，密码错误次数太多了吧？
进入cmd后分别执行以下

sqlplus /nolog
conn /as sysdba
alter user system identified by oracle account unlock;
alter user system identified by 密码;
分步执行，最好复制我的，我怕你自己打错了，因为有的地方必须有空格

Answer 2

alter user system account unlock;取消锁定用户帐号

Answer 3

sqlplus / as sysdbaSQL>alter user system identified by oracle account unlock;SQL>conn system/oracle; 这样子就可以了
