测试：通过控制文件自动备份恢复spfile。
数据库启用了快速恢复区，并且存在已自动备份的控制文件和参数文件，因为用如下命令恢复是没有问题的。

restore spfile to pfile '?/dbs/initPROD.ora' from '/u01/app/FRA/PROD/autobackup/2014_03_01/o1_mf_s_841034563_9k1x63p5_.bkp'; |
现在的问题是，既然使用了控制文件自动备份，那么，为什么通过自动备份直接恢复会报如下错误

原因其实挺简单，因为数据库没有mount，也就是说，并没有打开控制文件，所以，它并不知道自动备份的目录在哪儿，如果你show all一下的话，我们可以看到，所有的配置信息均为默认值

有的网友说，可以指定控制文件自动备份的目录即可，不过，我指定后，还是报同样的错误，如下：（/home/oracle目录下有自动备份的控备份片）

最后采用如下方式恢复成功

当然，如果你不“较劲”的话，直接指定绝对路径，也是一样可以恢复的。
