ora-00742 due to write lost

近期某客户环境不定期出现写丢失报错，到账数据库无法进行归档。

dbkedDefDump(): Starting a non-incident diagnostic dump (flags=0x0, level=3, mask=0x0)
----- Error Stack Dump -----
ORA-00742: Log read detects lost write in thread %d sequence %d block %d
ORA-00312: online log 4 thread 2: '+DATA/xxxxxx/onlinelog/group_4.695.1127508625'
----- SQL Statement (None) -----
Current SQL information unavailable - no cursor.

类似上述错误，Oracle在进行归档时发现redo log有写丢失的情况，即数据不一致（会进行校验），则抛出上诉错误。

ORA-00742错误不太好模拟，这里简单模拟一下ORA-00312.

首先创建测试表，并进行相关update操作，在进行update的同时，通过strace lgwr进程定位相关偏移量。

SQL>  select a.object_id,dbms_rowid.rowid_relative_fno(rowid) file#,dbms_rowid.rowid_block_number(rowid) blk#  from test0413
  2  a;

 OBJECT_ID      FILE#       BLK#

         9          1     133065

8 rows selected.


SQL> update test0413 set object_name='lizhenxu' where object_id=6;

1 row updated.

SQL> commit;

Commit complete.

定位到偏移量之后，这里我们可以借助bbed小工具来进行修改redo，以实现模拟写丢失的情况：

SQL> select dump('lizhenxu',16) from dual;

DUMP('LIZHENXU',16)
--------------------------------------------------------------------------
Typ=96 Len=8: 6c,69,7a,68,65,6e,78,75

SQL> select dump('enmotech',16) from dual;

DUMP('ENMOTECH',16)
--------------------------------------------------------------------------
Typ=96 Len=8: 65,6e,6d,6f,74,65,63,68

如上是我需要进行修改的数据并进行了16进制dump，下面来修改一下：

修改完成之后，我们来尝试切换一下redo log，看此时Oracle数据库是否能够进行正常归档。

从上述alert log来看，此时数据库已经报redo log corruption了，无法进行正常归档。我们进一步来看下归档进程的堆栈信息：

从上面的堆栈信息来看，与客户环境的报错相关堆栈是基本匹配的（客户环境是AIX平台，我这里是Linux）。由于我前面测试环境中，redo log组只有一个member成员，如果是每个redo log组有2个member，那么其中一个出现写丢失或者损坏，那么会影响归档吗？带着这个疑问，我再次进行了测试。

首先我这里先处理一下故障环境，然后增加了log member成员：

SQL>  alter database drop logfile group 2;
alter database drop logfile group 2
*

接下来我们继续重复上述的测试过程：

同时打开strace跟踪，方便定位redo的读写偏移量：

从上面跟踪信息来看，偏移量在25600位置，写了2个block，那么偏移量则为52. 接下来通过bbed定位到52 号block，进行修改：

BBED> set filename '/u01/app/oracle/oradata/data/OGGDB/onlinelog/redo03.log'

BBED> sum apply
Check value for File 0, Block 52:
current = 0x1428, required = 0x1428

完成redo 修改之后，我们这里在进行redo 切换，看看是否能够正常归档或者是像前面一样报错呢？

可以看到此时数据库是正常运行的，redo归档不受任何影响，这也是符合预期的。
