oracle 中 移动logfile ：出错

SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-00313: open failed for members of log group 1 of thread 1
ORA-00312: online log 1 thread 1: '/kuozhan/test/redo03.log'


移动到最后一步出错！～

前面几步的操作是：
shutdown immediate
ho mv /opt/oracle/oradate/orcl/redo03.log /kuo/test/
startup mount
alter database rename file '/opt/oracle/oradate/orcl/redo03.log' to '/kuo/test/log03.log';
alter database open;--->就是在这里出现上面的错误！

可能是删除的日志是current状态的原因!但是怎么解决呢？现在数据库到不了open了！

开始不知道怎么办，结果把group 1 删除了，现在使用如下方法恢复：
alter database until cancel;
alter datebase  open resetlogs;
shutdown immediate
startup
到此正常启动，OK!

附上操作过程以及现象;

日志组变成2个了，但是oracle启动成功了。
