recover时报错ora-289，有意思

oracle的alter database recover语句实在很弱智，明明目录中有arch文件，却不去找这个文件。
看下面的2个例子：

-- 例子1：
sys@ORALOCAL(10.1.26.26)> alter database datafile 'e:\test02.dbf' offline;

Database altered.

Elapsed: 00:00:02.73
sys@ORALOCAL(10.1.26.26)>
sys@ORALOCAL(10.1.26.26)> alter database recover datafile 'e:\test02.dbf';

Database altered.

Elapsed: 00:01:00.25
sys@ORALOCAL(10.1.26.26)> alter database datafile 'e:\test02.dbf' online;

Database altered.

Elapsed: 00:00:00.43
sys@ORALOCAL(10.1.26.26)>

-- 例子2：
sys@ORALOCAL(10.1.26.26)> alter database datafile 'e:\test02.dbf' offline;

Database altered.

Elapsed: 00:00:00.50
sys@ORALOCAL(10.1.26.26)> alter system switch logfile;

可见，不加automatic只能还原redo中的东西。

不过，如果我们用recover datafile语句，就没这么弱智了，至少还有个交互界面提示你输入auto，还是cancel还是指定某个arch：

sys@ORALOCAL(10.1.26.26)> recover datafile 'e:\test02.dbf';
ORA-00279: change 801230 generated at 12/08/2008 13:25:38 needed for thread 1

ORA-00280: change 801230 for thread 1 is in sequence #66

Specify log: {<RET>=suggested | filename | AUTO | CANCEL}
auto
Log applied.
Media recovery complete.
sys@ORALOCAL(10.1.26.26)>

另外，除了上述的方法，我们还能用rman来实现，连auto都不用指定了，呵呵：

test@ORALOCAL(10.1.26.26)> alter database recover datafile 'e:\test02.dbf';
alter database recover datafile 'e:\test02.dbf'

或者，在recover datafile之前set一下，也能和rman的效果类似的，不需要在另外的指定auto：

test@ORALOCAL(10.1.26.26)> alter database datafile 'e:\test02.dbf' offline;

Database altered.

结论：
恢复脱机的数据文件时候，如果恢复的内容不在online redolog中，我们可以：
1、recover datafile XXX 然后指定auto。
2、用rman recover datafile。
3、set AUTORECOVERY ON之后用recover datafile XXX。
4、尽量避免用alter database recover datafile。如果用，就用alter database recover automatic datafile XXX。
其实在oracle的文档中也说了（点击此处）：

It is also possible to use the SQL statement ALTER DATABASE RECOVER, but it is highly recommended that you use the SQL*Plus RECOVER command instead.

是不是9I的?我记得10G的alter database recover datafile 是会自动应用archive log的。

re OoNiceDream:我的数据库是9i的，那个官方文档上的话，也是9i的。
