Installation types

When you install EAServer, features are installed by default depending on the type of installation you select. The types of installations include:

Typical – installs the typical files required to develop EAServer applications.
Custom – you define which features to install. By default, features that are installed in a typical installation are selected for installation in a custom installation, but you can add or remove features.
Client Runtime – installs only the client runtime files, and Web server plug-ins. Select this option to run Java or C++ client applications or to use SSL connectivity from PowerBuilder clients, but not install the entire product set.

You are not required to install the client runtime if you are developing clients on a machine where the application server is installed. The server installation includes the core server files.

See Chapter 4, “Installing and Configuring a Web Server Redirector Plug-In,” for more information about the Web server plug-ins.
Full – installs all features.
Add Components – adds components to an existing 6.1 installation.
Upgrade – upgrades EAServer from version 6.0.0, 6.0.1, or 6.0.2.

Table 1-2 describes EAServer features and lists the features that are installed for each type of installation. A Full installation installs everything.
