$ oerr ora 1149
01149, 00000, "cannot shutdown - file %s has online backup set"
// *Cause: An attempt to shutdown normally found that an online backup is
//        still in progress.
// *Action: End the backup of the offending tablespace and retry this command.

--昨天测试环境,发现在shutdown immediate时出现错误,估计有人学习使用了用户备份模式.
--结束备份模式就可以解决这个问题,自己在模拟看看.
