This error usually indicates that there was a previous Oracle installation that left files behind or that there are no write permissions on /var and/or /tmp. This error can occur on Solaris and Linux.
Verify that the permissions on /var/tmp and /tmp directories are set to 777. Also, verify the directory /var/tmp/.oracle does not exist prior to the installation. If it does, remove it then continue with the install
