Fatal Error, no space left on device WLS

I have been changing linux distros and I've faced with an issue in which is simple to resolve but does not happen very often on Debian's distros. Currently I am using Fedora, to get more experience with RH like OS.

While building from scratch my environment, installing the WLS for testing purpose I have faced the following FE (Fatal Error, I call it fatality):

The fatality is clear text, during extraction there is no more space left; But where???

To find out on linux, just open an terminal and run the df command.

$df

On my bellow screenshot, my /tmp directory is almost full.

• As you can see my /tmp is 2G and is 79% full. There is not enough space for a WLS installation which takes a lot tmp space... I believe is about 1.2G of space, and setting a small 2G tmp like I did is a bad business.

• But why did I not have such issue using Debian distro? Well, a friend with more RH experience answered me: "Fedora does not clean tmp directory!!!" (Vaaapaaa, in your face response...)
• Well, after watching over the tmp I came with a possible theory. OS are not responsible for cleaning up tmp, but the programs that use this directory is, and Debians distro just want to be nice with us. 

I have listed a few commands that might be useful for this type of situation:

1. From the ehow blog I found the following commands in which needs to be run as root: 

a. finds and delete any file older than 10 days:
#find /tmp -mtime +10 |xargs rm -f 

b. Delete all empty directory from tmp:
#find /tmp -type d | xargs rmdir

*you can modify this commands to delete needed files, but this is a bad thing because some running programs might be using files from tmp directory; So be advise to be careful with what you delete. 

2. This is more elegant solution in which there no risk. If you have notice I am running a java command, therefore we will use a java solution for this issue without having to delete any files from tmp directory. 

a. create a tmp directory at your home user directory:  

$mkdir tmp
$ls
/home/"YourUser"/tmp

b. run the WLS jar installer with the followind java flag:  

java -Djava.io.tmpdir=/home/"yourUser"/tmp -jar wls1035_generic.jar

Either solution will work but I would rather use the second one; The screen shot taken bellow was when testing the commands from ehow blog.
