Insufficient free space in /tmp while installing SOA 12c

$JAVA_HOME/java -jar fmw_12.1.3.0.0_soa_quickstart.jar

Insufficient free space in /tmp/orcl4316142800341622207.tmp to extract the installer.  Actual 365 MB.  Required 3053 MB.

In my case we don't have free space under /tmp mount. So i have created /tmp directory under different location.

Fix:

1. mkdir -p /u01/tmp
2. chmod -R 777 /u01/tmp
3. export _JAVA_OPTIONS="-Djava.io.tmpdir=/u01/tmp"
4. java -jar fmw_12.1.3.0.0_soa_quickstart.jar
