===> 2875438 is the OS PID of DBW0 process which encountered the I/O error and is dead.

实例通过OS PID 643220的USER进程终止。

OS 日志 (/var/log on AIX) 报告 I/O 错误：

Date/Time: Wed Nov 2 06:29:52 CUT 2011

Description
USER DATA I/O ERROR

Probable Causes
ADAPTER HARDWARE OR MICROCODE
DISK DRIVE HARDWARE OR MICROCODE
SOFTWARE DEVICE DRIVER
STORAGE CABLE LOOSE, DEFECTIVE, OR UNTERMINATED

原因

可能是数据文件脱机/损坏：

查看OFFLINE文件：

select file#, status, name from v$datafile where status not in (‘SYSTEM’, ‘ONLINE’);

或
$ORACLE_HOME中的密码文件(orapw)/在数据库创建后创建的dbs中有问题。re is a problem in the password file found in $ORACLE_HOME/dbs which was created after the database creation. 从而导致同步问题且最终造成额外的错误信息：
ORA-01990: error opening password file $ORACLE_HOME/dbs/orapw.

或

DBW0 由于I/O 错误崩溃。这因此导致实例被终止，因为后台进程的终止会造成实例崩溃。

解决方案

数据文件损坏/脱机:
检查你是否有能从中还原任意问题数据文件的好备份。
1) 首先还原有问题的数据文件
2) Mount数据库并使这些数据文件联机

SQL> startup mount;
SQL> alter database datafile file1#, .. , filen# online;

3) 恢复数据库

SQL> recover database;

4) 打开数据库

SQL > alter database open ;

I/O 错误

联系你的系统/Unix 管理员并纠正导致I / O错误的硬件问题。
