解决方法1

参考：11.2.0.4 runInstaller: [INS-06006] Passwordless SSH connectivity not set up between the following nodes(s) (文档 ID 1597212.1)

将/etc/hosts文件里面主机名改为小写即可

解决方法2（在AIX 6.1有案例采用下面的方法解决）

ln -s /usr/bin/ksh /bin/bash

mkdir -p /usr/local/bin

ln -s /usr/bin/ssh-keygen /usr/local/bin/ssh-keygen

ln -s /usr/bin/ssh /usr/local/bin/ssh

ln -s /usr/bin/scp /usr/local/bin/scp
