Issue: Warning message about unsupported platform, not enough memory, or resolving host name is displayed. EPM System Installer checks whether your system has a supported operating system and meets minimum memory requirements, and it attempts to run the installation and attempts to discover the computer host name.
Solution: If you receive a memory warning or unsupported platform, be aware that your installation could have problems. If the machine host name resolves to an IP address, you receive a warning. Oracle recommends that you resolve the DNS lookup issue before proceeding. If you do not, rebooting the machine can cause your machine to resolve the host to a different IP address, probably breaking your previously working installation.
