利用smit chuser命令修改oracle用户的shell配置：Soft FILE size、Soft CPU time、Soft DATA segment和Soft STACK size的限制都为-1。
利用smit chgsys配置系统参数：设置Maximum number of PROCESSES allowed per user大于等于2048。
# su - oracle
$ echo $SHELL

连接Oracle用户，在环境变量中添加umask 022和AIX_THREAD_SCOPE环境变量。
将数据库安装目录授权给oracle用户：
# chown -R oracle:oinstall /data
建立安装目录：
$ mkdir -p /data/oracle/oradata
$ mkdir -p /data/oracle/product/10.2
在oracle用户的profile文件中添加下面的信息：
ORACLE_SID=zhtrade; export ORACLE_SID
ORACLE_BASE=/data/oracle; export ORACLE_BASE
ORACLE_HOME=/data/oracle/product/10.2; export ORACLE_HOME
PATH=$ORACLE_HOME/bin:$PATH; export PATH
DISPLAY=172.20.10.150:1.0; export DISPLAY
利用cpio –idcmv < 10gr2_aix5l64_database.cpio解压文件，然后利用图形方式开始安装。
在运行/data/software/Disk1/runInstaller进行安装之前，需要首先用root来运行rootpre.sh：
# ./rootpre.sh
./rootpre.sh output will be logged in /tmp/rootpre.out_10-12-22.02:41:36

下面运行runInstaller开始数据库软件的安装：
选择高级安装，对安装过程进行定制；
由于设置了ORACLE_BASE和ORACLE_HOME环境变量，所以oraInvertory目录和组信息不需要改变；
选择企业版，并加载中文语言；
ORACLE_HOME目录选择，这里默认是正确的；
Oracle检查安装条件时会监测AIX6超过了预期的5.2或5.3，直接忽略这个问题开始安装；
选择安装类型的时候选择仅安装数据库软件；
最后 用root运行两个脚本，安装完成。
# /data/oracle/oraInventory/orainstRoot.sh
