AIX 5300-05与Oracle IO协调问题

最近运行Oracle的服务器只要工作任务非常大IO占用达到100%时间过长后，实例就会出现down的情况。查看alert.log后系统报：

Errors in file /home/oracle/admin/****/bdump/****_ckpt_1085840.trc:
ORA-00206: error in writing (block 3, # blocks 1) of control file
ORA-00202: control file: '/****/control03.ctl'
ORA-27072: File I/O error
IBM AIX RISC System/6000 Error: 22: Invalid argument

下面是Oracle给出的解决方案：（竟然是Oracle与AIX 5300-05的一个IO协调BUG，鄙视他们一下）

All Oracle 9i, 10gR1 and 10gR2 Database Customers running on AIX 5L V5.3 Technology Level 5 (TL 5300-05) must install an IBM AIX fix and an Oracle Database patch to bring the OS and Database environments to the correct levels. 

Please follow these steps:

IY89080. The fix is available as 5300-05-01 as well as 5300-06 is available which is cumulative
(IY89080 is included).

For systems running ML06 and above, you only need to install Oracle patch.
