存储故障时的ORA-7445错误

今天由于存储的磁盘故障，导致了一台服务器的DOWN机，没想到Oracle在出现硬件错误的时候也会报ORA-7445错误。

在alert文件中，可以找到下面的错误信息：

LGWR: terminating instance due to error 340ITPUB个人空间.S1w?c$Rn\C
Instance terminated by LGWR, pid = 544

从错误信息不难发现，问题出现在IO系统上，由于Oracle无法执行正常的IO操作，导致数据库最终被LGWR进程中止。

先来看看集中错误信息：

ORA-27063 skgfospo: number of bytes read/written is incorrect
Iq)v dty%b0Cause: The number of bytes read/written as returned by AIOWAIT does not match the original number, additional information indicates both these numbers.ITPUB个人空间+K&j ?0S!BJCz
Action: Check errno.

ORA-00345 redo log write error block string count string
%qAX$?na*Sf\UY0Cause: An I/O error occurred while writing the log.
5}`GVL$sm0Action: Correct the cause of the error, and then restart the system. If the log is lost, apply media/incomplete recovery.

ORA-00340 IO error processing online log string of thread string
R&|+l_V0Cause: An I/O error occurred on the named online log.ITPUB个人空间:R\1N0Dh8[
Action: Restore accessibility to the file or restore the file from backup.

ORA-00312 online log string thread string: 'string'ITPUB个人空间QGdV}&Y0l:^.T
Cause: This message reports the file name for details of another message.
f}jqb#oX(ik S0Action: Other messages will accompany this message. See the associated messages for the appropriate action to take.

ORA-00449 background process 'string' unexpectedly terminated with error string
\;KO
yj^'A(^\0Cause: A foreground process needing service from a background process has discovered the process died.
1Q1]-G1^&F[&r0^0Action: Refer to the message code given in the message and the trace file for the foreground and the background processes.

可以看到，这些错误都是和IO错误相关，更具体一点，基本上都是由于LGWR进程无法正确的写入数据造成的。

而上面的7445错误就比较奇怪了，检查一下ORA-7445对应的TRACE文件：

上面的信息是这个ORA-7445错误的完整信息，可以看到，由于IO出现了问题，导致ORA-7445错误很多的内容没有记录完全，连出错的函数信息都没有记录下来。

不过这里还可以出错的SQL语句，这个SQL语句其实是由于我当时正在SQLPLUS中执行SHOW SGA，而这个正好发生了硬件的故障，从而导致了这个7445错误的产生。

而错误信息中的随后的两个ORA-7445错误，是Oracle的DBWR进程尝试写UNDO表空间的数据文件时，出现了IO错误所引发的，其错误信息摘要如下：

由于错误本身的特殊性，这个ORA-7445并没有什么参考性，只是记录一下错误情况。
