oracle 账号解锁 java.sql.SQLException: ORA-28000: the account is locked

日志报错：ORA-28000: the account is locked

1、plsql登录提示用户被锁定

2、sys登录sqlplus登录查看

SQL> select username,account_status from dba_users t where t.username='XXX';

3、解锁

SQL> alter user XXX account unlock;

系统日志被覆盖了，原因大概是：系统连接oracle次数超过限制

改成30次

alter profile default limit FAILED_LOGIN_ATTEMPTS 30;
