一，安装JAVA6
1，用root用户登录到AIX系统中。
2，使用如下命令确定操作系统位数：
bootinfo -k
如果结果为：3，则表示AIX系统为32位，请勿安装64位的JVM。
3，用mkdir /tmp/jvm命令建立一个目录，并将Java6.sdk（如果是64位的AIX，推荐选用Java6_64.sdk）用FTP上传至/tmp/jvm目录中。
4，键入smit命令，进入如下画面：

12，安装验证，使用如下命令：
/usr/java6/bin/java -version
得到如下结果，说明安装正确完成。
java version "1.6.0"
Java(TM) SE Runtime Environment (build pap3260sr4ifix-20090417_02(SR4+IZ48590))
IBM J9 VM (build 2.4, J2RE 1.6.0 IBM J9 2.4 AIX ppc-32 jvmap3260sr4ifx-20090409_33254 (JIT enabled, AOT enabled)
J9VM - 20090409_033254_bHdSMr
JIT - r9_20090213_2028
GC - 20090213_AA)
JCL - 20090228_01
二，环境变量配置：
1，由于AIX在安装的过程中，会默认安装JAVA1.4，所以需要先删除/etc/environment文件中，PATH环境变量中的/usr/java14/jre/bin:/usr/java14/bin。
2，编辑/etc/profile文件，在PATH变量中，加入/usr/java6/jre/bin:/usr/java6/bin两项，并在文件未尾加上如下一行：
export JAVA_HOME=/usr/java6
3，重新用root用户登录，以使环境变量生效。
4，验证，使用java -version命令，得到如下结果：
java version "1.6.0"
Java(TM) SE Runtime Environment (build pap3260sr4ifix-20090417_02(SR4+IZ48590))
