我们对控制文件的一些常见操作，比如：
1）如何多路镜像控制文件？
正常关机，cp一份，修改pfile，生成spfile，重启数据库
2）查看控制文件的位置？
i SQL> show parameter control_files
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_files string /u01/app/oracle/oradata/ORCL/c
ontrolfile/o1_mf_7xzsjpnk_.ctl
, /u01/app/oracle/flash_recove
ry_area/ORCL/controlfile/o1_mf
_7xzsjq6j_.ctl
ii SQL> select name from v$controlfile;
NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/ORCL/controlfile/o1_mf_7xzsjpnk_.ctl
/u01/app/oracle/flash_recovery_area/ORCL/controlfile/o1_mf_7xzsjq6j_.ctl
iii SQL> select value from v$parameter where name='control_files';
VALUE
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/ORCL/controlfile/o1_mf_7xzsjpnk_.ctl, /u01/app/oracle/fl
ash_recovery_area/ORCL/controlfile/o1_mf_7xzsjq6j_.ctl
3）查看控制文件的内容？
alter database backup controlfile to trace；
然后到udump下去找
