一、环境
1. AIX 5.3 系统,安装 Oracle 10.2.0.1 for AIX AIX(生产环境) 以下以 A 机称 2. Windows 2003 系统,安装 Oracle 10.2.0.1 for windows , windows(备用环境) 以下以 B 机称 二、背景 由于生产环境服务器 IBM 服务器升级 CPU 时造成底座上脚针折断,为保障生产不停,便将 A 服务器上的 Oracle 做 exp 导出,从而导入到备用 B 服务器上让应用能正常运行,等 IBM 将 硬件弄好后再导回生产环境上跑。 三、问题 在 IBM 将问题解决后,我们将备机数据库 exp 出来,并以二进制方式 ftp 到生产环境 上时 imp user/password fromuser=user touser=user file=XXXX.dmp ignore=y feedback=10000 导入工作进行一会就报错,报错信息如下: 技术文档 中国·九州通集团·信息技术总部 第 2 页 共 7 页
3.
分析:当导入到数据量很大的表时就会报这样的错,
判断:在初步判断后感觉是临时表空间和 undo 表空间过小所导致的 操作:修改临时表空间和 undo 表空间后再导入 再来一次 导入工作进行一会就报错,报错信息如下: 结果:还是报以上错误 分析:刚才的大表已经导入进去,但在这个更大的表又出现报错, 检查 alter 日志,发现在导入时产生 ORA-27061 报警 技术文档 中国·九州通集团·信息技术总部 第 3 页 共 7 页

ORA-27061: skgfospo: waiting
for async I/Os failed IBM AIX RISC System/6000 Error: 22: Invalid argument 判断:根据日志显示及百度查证,是异步 IO 出现问题 这个由于异步 IO 引起的问题,在 AIX 5.3 TL6 下,使用文件系统,打开 Oracle 的异步 IO 选项的时候,经常 会出现。当异步 IO 的请求(队列)超出 MAXREQS 的时候,由于 AIX 上 AIOWAIT 的问题,会导致返回值是 错误的,Oracle 发现该错误后,就会出现问题。如果正好是某些重要的后台进程碰到这样的错误,会导致数据 库宕掉。 步骤: 1. AIX 系统升级 2. 安装 IBM 的 IZ03260 补丁包 四、问题解决 下载补丁 发现 AIX 操作系统版本太低,去 IBM 官方网站寻找补丁。 1. ftp://download2.boulder.ibm.com/ecc/hsb/H03205176/ 2. ftp://ftp.software.ibm.com/aix/efixes/iz03260/ 3. http://www-933.ibm.com/eserver/support/fixes/fixcentral/pseriesfixpackinformation/5300- 06-01-0722 技术文档 中国·九州通集团·信息技术总部 第 4 页 共 7 页

#smit mksysb
在"备份设备或文件"中添入"/dev/rmt0"后回车. 系统会运行很长时间, 等到屏幕显示 OK 后拿出磁带. 这时候, 系统备份完成. 注意:mksysb 仅备份 rootvg 中已安装的文件系统. 开始 AIX 补丁升级 # smit install_update 进入后选 update software by fix,后根据提示可以完成 技术文档 中国·九州通集团·信息技术总部 第 6 页 共 7 页
