Your problem stems from the initial setup, which included creating a separate disk partition for the /tmp directory. Sophisticated disk partitioning was a common task in past to prevent a bad process from filling up a disk and hence stop the core system from functioning in the end, or to reserve disk space for certain logical areas. Considering how fast and cheap disk space has become, there is more reason to avoid partitioning were it is not essentinally necessary.
If you need more tmp space, e.g. to Install Oracle database, you can assign a temporary tmp directory and put it under /home.
<pre>
sudo mkdir /home/tmp2
sudo chmod 1777 /home/tmp2
</pre>
Set the tmp directory prior to starting your application:
<pre>
export TMPDIR=/home/tmp2
./runInstaller.sh
</pre>
To permanently relocate /tmp you will need to boot the system into single user mode, edit /etc/fstab to remove your tmp partiton, and create a /tmp directory with 1777 permissions under root, or create a symlink to another location.
