aix6.1上安装10g r2注意事项

/article/3595426.html

总体安装上与其它linux上没有太大的区别

1.在安装时根据提示运行的脚本/oracleDisk/Disk1/rootpre/rootpre.sh时报以下错误，可以先跳过，不影响安装（关于异步IO设置)

Configuring Asynchronous I/O....

Asynchronous I/O is not installed on this system.

You will need to install it, and either configure it yourself using

'smit aio' or rerun the Oracle root installation procedure.

Configuring POSIX Asynchronous I/O....

Posix Asynchronous I/O is not installed on this system.

You will need to install it, and either configure it yourself using

'smit aio' or rerun the Oracle root installation procedure.

Checking if group services should be configured....

2.在安装时候检查系统条件时报如下信息，主要是10G出来时，AIX6还未出现，提示兼容警告，后面通过修改oraparam.ini

无果情况下采用MOS提示:./runInstaller -ignoreSysPrereqs ,可顺利安装以及打补丁；

Checking operating system package requirements ...

Check complete. The overall result of this check is: Not executed <<<<

OUI-18001: The operating system 'AIX Version 6100.04' is not supported.

Recommendation: Install the required packages before continuing with the installation.

Checking recommended operating system patches

Check complete. The overall result of this check is: Not executed <<<<

OUI-18001: The operating system 'AIX Version 6100.04' is not supported.

Recommendation: You may actually have installed patches which have obsoleted these, in which case you can successfully continue with the install. If you have not, it is recommended that you do not continue. Refer to the readme to find out how to get the missing
patches.

3.安装时候最好选择先安装软件再数据库的顺序

4.升级补丁包时也与安装库顺序一样，先运行补丁包中的:./runInstaller安装软件后，再通过DBUA升级库，升级过程中根据提示关闭归档，备份数据库，将并发数开到最大加快升级的时间，CPU32线程用了30打补丁，速度还是可以的；升级补丁包时有个提示运行命令/usr/bin/slibclean，用ROOT运行后即可；

5.升级完重启下机器看下还存在什么问题；
