Error OUI-10207 on installing Oracle 10g

When I’m trying to install Oracle 10g on a Linux operating system, I got this error “OUI-10207: there is not enough disk space in the OUI swap area”, but I already set all the variables correctly upon installation. With Oracle Enterprise Linux 5 I have installed it well in which I install VMware on a 64-bit Microsoft Windows 7. Any suggestions to this? Thank you.
