首先检查系统是否满足数据库安装需要：
# /usr/sbin/lsattr -E -l sys0 -a realmem
realmem 32604160 Amount of usable physical memory in Kbytes False
# /usr/sbin/lsps -a

64
系统内容要求至少1G内存，SWAP分区大小对于大于8G的内存需要75％内存大小，当前配置为50％内存大小，虽然足够使用，但是Oracle检查可能会报错，需要忽略检查错误才行。
要求AIX操作系统在5.2以上：
# oslevel -r
6100-06
当前为6，满足要求。
检查操作系统文件集：
# lslpp -l bos.adt.base bos.adt.lib bos.adt.libm bos.perf.perfstat bos.perf.libperfstat bos.perf.proctools

对于6来说，版本足够高，因此安装文档上描述的补丁集不再需要。
# cat /etc/netsvc.conf | grep hosts
# hosts = value [, value]
# Use one or more of the following values for the hosts keyword:
# The auth option is only valid when used in conjunction with a service value for the hosts keyword.
# local Searches the local /etc/hosts file for resolving names
# local4 Searches the local /etc/hosts file for resolving only IPv4 addresses
# local6 Searches the local /etc/hosts file for resolving only IPv6 addresses
# hosts = nis=auth, bind6, dave4
# hostname
ZHY-DT-1
# domainname
# cat /etc/hosts | grep `eva l hostname`
172.20.20.1 ZHY-DT-1
验证系统是否仅使用/etc/hosts作为唯一验证名次的方式。
利用smit security创建oinstall、dba组。
利用smit security创建oracle用户，指定primary用户组oinstall，GROUPSET为dba，指定用户创建目录/home/oracle
# id oracle
uid=202(oracle) gid=201(oinstall) groups=202(dba)
# passwd oracle
确认用户创建成功并修改密码。
# id nobody
uid=4294967294(nobody) gid=4294967294(nobody)
确认nobody
