下面来看一位前辈的测试

结论是:
1.SNAPSHOT CONTROLFILE 不能直接copy成control file,如果数据库已经shutdown
2.可以通过rman,将SNAPSHOT CONTROLFILE 恢复成控制文件
3.如果数据库没有shutdown,可以直接copy SNAPSHOT CONTROLFILE 成控制文件,但仍需要恢复(因为他是旧的)

下面是我的测试步骤:
—————————————
查看snapshot controlfile的备份设置:
RMAN> SHOW SNAPSHOT CONTROLFILE NAME;

RMAN configuration parameters are:
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;
