【案例】Oracle报错ORA-16433非归档丢失redo无法启动的恢复过程

 

转惜纷飞


今天ML的群中女神和travel在纠结一个恢复的问题,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:

SQL> SELECT name FROM v$datafile;

NAME
------------------------------------------------
/u01/app/oracle/oradata/travel/system01.dbf
.........
/u01/app/oracle/oradata/travel/users01.dbf

SQL> SELECT member FROM v$logfile;

-------------------------------------------------

/u01/app/oracle/oradata/travel/redo01.log

SQL> ALTER DATABASE RENAME file ‘/u01/app/oracle/oradata/travel/system01.dbf‘ TO ‘/home/oracle/travel/travel/system01.dbf‘;
SQL>  ALTER DATABASE RENAME file ‘/u01/app/oracle/oradata/travel/sysaux01.dbf‘ TO ‘/home/oracle/travel/travel/sysaux01.dbf‘;

SQL> ALTER DATABASE RENAME file ‘/u01/app/oracle/oradata/travel/redo02.log‘ TO ‘/home/oracle/travel/travel/redo02.log‘;
SQL> ALTER DATABASE RENAME file ‘/u01/app/oracle/oradata/travel/redo03.log‘ TO ‘/home/oracle/travel/travel/redo03.log‘;   

SQL> SELECT name FROM v$datafile;

NAME
-------------------------------------------------
/home/oracle/travel/travel/system01.dbf
/home/oracle/travel/travel/sysaux01.dbf
/home/oracle/travel/travel/undotbs01.dbf
/home/oracle/travel/travel/users01.dbf

SQL> SELECT member FROM v$Logfile;

MEMBER
-------------------------------------------------
/home/oracle/travel/travel/redo03.log
/home/oracle/travel/travel/redo02.log
/home/oracle/travel/travel/redo01.log

此时,进行recover,会报错ORA-16433,如下:

SQL> recover DATABASE;
ORA-00283: recovery SESSION canceled due TO errors
ORA-16433: The DATABASE must be opened IN READ/WRITE mode.


SQL> recover DATABASE USING backup controlfile until cancel;
ORA-00283: recovery SESSION canceled due TO errors
ORA-16433: The DATABASE must be opened IN READ/WRITE mode.

SQL> ALTER DATABASE OPEN;
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:

---重建controlfile

开始开始进行recover:
SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: ‘/home/oracle/travel/travel/system01.dbf‘

ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: ‘/home/oracle/travel/travel/system01.dbf‘

ORA-01112: media recovery not started
因为本身是非归档,所以这个不完全恢复的步骤无非是为了后面可以进行open resetlog。然后停库,加入隐含参数进行open:

SQL> shutdown immediate
ORA-01109: DATABASE NOT OPEN

DATABASE dismounted.
ORACLE instance shut down.
SQL> startup nomount  pfile=/home/oracle/travel/travel/b.ora

此时alert log对应的错误如下:

ALTER DATABASE OPEN
*
ERROR at line 1:

最后dunmp controlfile和CURRENT redo logfile,发现low cache rba信息居然是最大值:

SQL> ALTER system  SET events ‘immediate trace name controlf level 4‘   ;

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:

此时停库,然后在pfile中加入隐含参数:

接着再次进行mount,并进行scn 推进:

这里说明一下是我的alert log里面还出现了数据字典不一致的问题,因为毕竟是强制open的,如下:

这个ora-600错误很常见了,通过是index信息不一致。

其trace内容如下:

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。
