./RUNINSTALLER -oracle_base /oracle/SID -tmp /oracle/SID/temp -check
For this command to work, In fact the /oracle/SID should have the free space as I believe the tmp is pointing to /oracle/SID/temp. The RUNINSTALLER will extract a set of files and scripts in a directory when it is started. I have faced this in the past and fixed it by extending the /oracle/SID file system space.
