Before you install, ensure that the hosts in your deployment meet the minimum hardware and operating system requirements. For the latest information on the supported platforms and software and hardware requirements, refer to the following:
For Communications Suite product components, see theSun Java Communications Suite 5 Release Notes.
For Java ES product components, see Platform Requirements and Issues in Sun Java Enterprise System 5 Release Notes for UNIX.
If the operating system found on the host does not satisfy Communications Suite recommendations, the installer cannot proceed. You must resolve this problem before installation.
