Set JAVA_HOME environment variable for root user on AIX

Setting variables in /etc/profile

For setting JAVA_HOME in /etc/profile enter following statements:

    JAVA_HOME=/usr/java6_64/jre
    export JAVA_HOME

    PATH=$JAVA_HOME/bin:$PATH
    export PATH

You have to login again to see the changes. I am using putty, so will re-open it and login with root user.
Verifying variables

To verify your changes you can echo JAVA_HOME and PATH variables.

    # echo $JAVA_HOME
    /usr/java6_64/jre

  # echo $PATH
    /usr/java6_64/jre/bin:/usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin

  # which java
    /usr/java6_64/jre/bin/java
