一，安裝JAVA6
1，用root用戶登錄到AIX系統中。
2，使用如下命令確定操作系統位數：
bootinfo -k
如果結果為：3，則表示AIX系統為32位，請勿安裝64位的JVM。
3，用mkdir /tmp/jvm命令建立一個目錄，并將Java6.sdk（如果是64位的AIX，推薦選用Java6_64.sdk）用FTP上傳至/tmp/jvm目錄中。
4，鍵入smit命令，進入如下畫面：

12，安裝驗證，使用如下命令：
/usr/java6/bin/java -version
得到如下結果，說明安裝正確完成。
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，環境變量配置：
1，由于AIX在安裝的過程中，會默認安裝JAVA1.4，所以需要先刪除/etc/environment文件中，PATH環境變量中的/usr/java14/jre/bin:/usr/java14/bin。
2，編輯/etc/profile文件，在PATH變量中，加入/usr/java6/jre/bin:/usr/java6/bin兩項，并在文件未尾加上如下一行：
export JAVA_HOME=/usr/java6
3，重新用root用戶登錄，以使環境變量生效。
4，驗證，使用java -version命令，得到如下結果：
java version "1.6.0"
Java(TM) SE Runtime Environment (build pap3260sr4ifix-20090417_02(SR4+IZ48590))
