CONFIGURE SNAPSHOT CONTROLFILE NAME TO ‘/u01/ora9a/product/9.2/dbs/snapcf_tt9a.f’; # default

RMAN>

下面模拟控制文件丢失的恢复
$ ls
control01.ctl cwmlite01.dbf indx01.dbf redo02.log temp01.dbf users01.dbf
control02.ctl drsys01.dbf odm01.dbf redo03.log tools01.dbf xdb01.dbf
control03.ctl example01.dbf redo01.log system01.dbf undotbs01.dbf
$ rm cont* –删除控制文件
$ ls
cwmlite01.dbf example01.dbf odm01.dbf redo02.log system01.dbf tools01.dbf users01.dbf
drsys01.dbf indx01.dbf redo01.log redo03.log temp01.dbf undotbs01.dbf xdb01.dbf
$
在控制文件被删除后，数据库还能正常操作：
SQL> insert into test(no) values(4);

1 row created.

SQL> commit;

Commit complete.

SQL> alter system switch logfile;

System altered.

SQL> alter system checkpoint;

没有控制文件，查询失败
现在将SNAPSHOT CONTROLFILE copy到对应目录，尝试直接恢复成控制文件:
SQL> !
$ pwd
/u01/ora9a/oradata/tt9a
$ cp /u01/ora9a/product/9.2/dbs/snapcf_tt9a.f control01.ctl

注意，此时不要起停数据库，否则这样恢复的控制文件仍不可用
