The following additional requirements should be met before installing the Sun Java System Application Server software.
Free space — Your temporary directory must have a minimum of 35MB free for Sun Java System Application Server installation, and 250 MB of free space for the SDK installation.
Using the uninstall program — If you need to remove the Application Server from your system, it is important to use the uninstall program that is included with the software. If you attempt to use another method, problems will arise when you try to reinstall the same version, or when you install a new version.
Free ports — You must have seven unused ports available.
The installation program automatically detects ports in use and suggests currently unused ports for the default settings. By default, the initial default ports are 8080 for HTTP, 8181 for HTTPS, and 4849 for the Administration Server.
The installation program will detect used ports and assign two others for you: Sun Java System Message Queue (by default, 7676), and IIOP (by default, 3700 for IIOP and 1060 and 1061 for IIOP/SSL). If these default port numbers are in use, the installation program will assign a random port number from the dynamic port range (note that this may not be the next available port number).
Starting previously-installed servers (UNIX) — unless you are replacing the previously installed server, you should start it before you begin the Sun Java System Application Server 8.2 installation process. This allows the installation program to detect ports that are in use and avoid assigning them for other uses.
Replacing previously-installed servers (UNIX) — if you have an older version on the Sun Java System Application Server installed that you wish to replace with the current Application Server, you should stop it before installing the new server. Use the installation program upgrade wizard to upgrade the server.
Shutting down firewall (Microsoft Windows) — You must stop any firewall software before installing the Sun Java System Application Server software, because some of this software disables all ports by default. The installation program must be able to accurately determine which ports are available.
