In determining the optimal amount of memory for your installation, the best practice is to load test your site. See Oracle Application Server Performance Guide for details. For Java applications, either increase the maximum heap allocated to the OC4J processes, or configure additional OC4J processes to utilize this memory. For sites with substantial traffic, increasing the amount of memory further may improve your performance. However, for most production sites, you should configure at least 1 GB of physical memory. The memory requirements provided for the various installation types represent enough physical memory to install and run Forms and Reports Services. You can install Forms and Reports Services on a computer that uses static IP or DHCP-based IP. For information on turning on the naming service, see Oracle Application Server Reports Services Publishing Reports to the Web. Therefore, if your installation is on a standalone (non-networked) host machine or you are connected to a network through VPN, turn off the Reports out-of-the-box broadcast mechanism, and turn on the Reports naming service support for discovery instead. That is, even if the host machine is connected to the network through VPN, Oracle Reports clients cannot discover and communicate with Reports Server(s). Note that the definition of a "network" does not include a Virtual Private Network (VPN). Specifically, Oracle Reports clients cannot discover and communicate with Reports Server(s). As a result, you cannot use OracleAS Reports Services. If the host machine is not in a network (that is, it is a standalone machine), then the in-built broadcast mechanism does not work. Note: The Reports default broadcast discovery mechanism requires the host machine to be inside a network. You have to perform some configuration tasks when you connect it to the network see Oracle Application Server Administrator's Guide for details. If you are installing Forms and Reports Services on a standalone computer, you can connect the computer to a network after installation. You can install Forms and Reports Services on a computer that is connected to a network, or on a standalone computer (not connected to the network). For example, Windows 2000 with Terminal Services is not supported. Note: Forms and Reports Services is not supported on Windows operating systems that include Terminal Services. If you are running Windows XP with Service Pack 2, see Document ID 280874.1 on the Oracle MetaLink site (. You can install other Forms and Reports Services installation types on Windows XP (the installer displays a warning, but lets you continue), but they are not supported on Windows XP. J2EE and Web Cache middle tier running on Windows XP, using services from an OracleAS Infrastructure running on a different (non-XP) platform J2EE and Web Cache middle tier without Oracle Application Server Infrastructure Microsoft Windows XP is supported only for these two types: Microsoft Windows Server 2003 (32-bit) with Service Pack 1 Microsoft Windows 2000 with Service Pack 3 or later
