How to install IBM Java 7?

If you want to run Java programs, then you should install JRE
If you want to develop Java programs, then you should install Java SDK (previously called as JDK). SDK also contains JRE

So, if someone ask you to install Java then install Java SDK

How to install Java 7 on AIX 7?

1st check what version of Java is compatible with AIX OS version

Refer : http://www.ibm.com/developerworks/java/jdk/aix/service.html


oslevel            ### check AIX OS version

bootinfo -K     ### AIX OS architecture 32bit or 64bit

Lets say it's 64bit, so we want to install 64bit java version

We must be registered with IBM with some login name and password to download Java SDK software

Once downloaded perform following steps to install:

Download Java and save in /tmp/ directory

mkdir /tmp/java7_64

cp /tmp/Java7r1_64.sdk.tar.gz /tmp/java7_64

cd /tmp/java7_64

gunzip -d Java7r1_64.sdk.tar.gz

tar xvf Java7r1_64.sdk.tar
