11.2.0.3版本，非归档，大概是rm掉current的log，然后重建
controlfille后恢复导致一系列问题，并最终出现ora-600 2662错误，虽然这个错误很常见，但是你发现推进scn
也是无法open，感觉有点怪，远程了女神的电脑，操作不便，最后将文件压缩传过来，我在自己的vmware进行了恢复。
由于环境的差异，所以解压后我先进行rename file操作，如下：
SELECT name FROM v$datafile;

此时,进行recover，会报错ORA-16433，如下：
recover DATABASE;
ORA-00283: recovery SESSION canceled due TO errors
ORA-16433: The DATABASE must be opened IN READ/WRITE mode.
recover DATABASE USING backup controlfile until cancel;

ALTER DATABASE OPEN
*
ERROR at line 1:
ORA-01113: file 1 needs media recovery
ORA-01110: DATA file 1: '/home/oracle/travel/travel/system01.dbf'
关于该错误，通过oerr命令可以大概了解一下其含义，如下：
[oracle@11gR2_primary ~]$ oerr ora 16433
16433, 00000, "The database must be opened in read/write mode."
// *Cause: An attempt was made to open the database in read-only mode after an
// operation that requires that the database be opened in read/write
// mode.
// *Action: Open the database in read/write mode. The database can then be
// opened in read-only mode.
通过这个错误，我们可以得出一个信息，数据库可以以read only模式打开，换句话讲，你查询如下几个值都是一样的：
select checkpoint_change# from v$database; --来自controlfile
select checkpoint_change# from v$datafile; --来自controlfile
select checkpoint_change# from v$datafile_orader; --来自datafile header
其实，通常来讲，只要上述几个值一样，那么我们的db应该都是可以直接open打开的，然而，这里却不行，read only都不行，我试过。
然后下面就开始我的恢复工作。
第一次尝试恢复：

可以看到实际上current redo的LWN RBA是对的，为1.2.10，是小于on disk rba (0×1.3.0)的。那么这里为什么会出现这个情况？
猜测可能是写紊乱了。到这里也就比较明白了，仍然是conrolfile有问题。
既然如此，那么我直接将controlfile文件rm掉，然后再次重建。如下：

seg/obj: 0×12 这是obj$对象，属于bootstrap$核心对象，涉及到这类的对象处理相对麻烦，针对这类情况，数据库open后都建议
把数据导出，然后重建库，我这里就不在继续描述这个ora-600错误了，我博客也有类似的例子。
最后来个小节：
1. oracle通过系统checkpoint scn，datafile checkpoint scn,start scn三者之间的比较来判断数据文件是否需要进行介质恢复.
2. 在redo 线程打开的情况下，即数据库open的情况下，stop scn会被设置为无穷大，当正常关闭时，stop scn等于datafile scn.
这里需要注意的是，stop scn是存放在controlfile中的，网上部分资料说是存在datafile header中，这个说法是错误的。
3. oracle在open之前是先判断是否进行介质恢复，然后再是判断是否进行instance recovery。
4. 关于4种scn的关系如下：
system checkpoint scn — 存放在controlfile中
datafile checkpoint scn –存放在controlfile中
start scn —存放在datafile header中
stop scn —存放在controlfile中
system scn，datafile checkpoint scn，start scn，这3种scn用于判断数据文件是否需要进行介质恢复。这3个相等这不需要介质恢复。
如何这4个都相等，那么就不需要进行实例恢复。stop scn是用于判断是否进行实例恢复的。
5. 如果stop scn比其他的几个scn要大，那么就需要进行instance recover，需要进行扫描redo，实例恢复的起点是low cache rba，终点
是redo log的最末端。
