众所周知，oracle数据库的控制文件是很小的二进制文件，是打不开的，打开了也是乱码，但可以通过转储文件来获得控制文件的详细信息。
alter database backup controlfile to trace ;
再到这个路径去打开控制文件：
D:\oracle\product\admin\cisdb\udump\(我的机器是这个路径)
在$ORACLE_HOME/admin/SID/udump下可找到最新生成的TRACE文件
cisdb_ora_3212.trc
使用记事本打开即可：
很详细：

把上面的控制文件保存在一个脚本中，比方：recreate_controle.sql
再在SQL>里运行该脚本即可生产控制文件。
SQL>@recreate_controle.sql
