The following additional requirements should be met before installing the Sun GlassFish Enterprise Server software.
Free space: your temporary directory must have a minimum of 35MB free for Sun GlassFish Enterprise Server installation, and 250 MB of free space for the SDK installation.
Using the uninstall program: If you need to remove the Enterprise 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 domain. By default, the initial default ports are:
8080 for HTTP, 8181 for HTTPS
3700 for IIOP, 3820 for IIOP/SSL and 3920 for IIOP/SSL with Mutual Authentication
4848 (HTTP) for the Administration Server
8686 (RMI) port for pure JMX Clients
Starting previously-installed servers (UNIX) — unless you are replacing the previously installed server, you should start it before you begin the Sun GlassFish Enterprise Server 2.1 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) — Refer to the Sun GlassFish Enterprise Server 2.1 Upgrade guide for complete instructions for upgrading from a previous version of the Enterprise Server.
Shutting down firewall (Microsoft Windows) — You must stop any firewall software before installing the Sun GlassFish Enterprise 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.
