The installer runs a check to determine if your host has sufficient memory, disk space, and swap space for the components you selected.
If the disk space found on the host is insufficient, the installer cannot proceed. You must resolve the problem before you can resume the installation.
If the memory or swap space found on the host do not satisfy Java ES recommendations, the installer displays a warning. Installation can proceed, but you should resolve the problem later.
The recommendation is, you should resolve the Swap requirements immediately before installing. If the Swap space is not matching the requirement, the Portal Server configuration may fail.
On Solaris 10, memory check is not performed if you are installing into a non-global zone.
