OEM 12C Agent upgrade failed with an error 'The space required for the upgrade at /tmp/xxx is not sufficient. Free the space at /tmp/xxx or provide a different staging location

Problem

The space required for the upgrade at /tmp/tmp_2015_07_23_10_50_01_029 is not sufficient. Free the space at /tmp/tmp_2015_07_23_10_50_01_029 or provide a different staging location

The jar file is /u04/Grid12cr5/oms12cr5/oms/sysman/jlib/auc_prereqs.jar

 

On upgrading an agent from 12.1.0.2.0 to 12.1.0.5.0, I faced the following issue:

Solution 

Since I chose the default staging location for the 'Stage Location', Grid pushed the files to /tmp directory. Instead, we can choose a directory where we have some space. I have chosen /u04 as I have enough space there:

Now the upgrade just goes smooth:
