Sun Java Enterprise System 2005Q4 Installation Guide for UNIX

How the Java ES Installer Works

Sun JavaTM Enterprise System (Java ES) integrates a number of Sun server-side products into a system that provides the server software needed to support distributed enterprise applications. In this document, these products are referred to as the Java ES components. A single installer is provided for installing the Java ES components in various combinations. Because of the complex interrelationships of these components, installation requires much more preinstallation and postinstallation effort than is required to install a single component

This section contains the following subsections:

Java ES Components Used in This Release

The Java ES software associated with the 2005Q4 release includes the following selectable components. (The abbreviated names used in this guide follow the name and version.)

To see the full list of services and subcomponents as displayed in the Java ES installer, refer to Appendix A, Java ES Components for This Release. This appendix also lists the shared components that are provided with this release.

Installer Modes

The Java ES installer is an installation framework that uses the Solaris pkgadd or Linux rpm utility to transfer Java ES software to your system. You can install Java ES interactively or by means of a reusable script.


Tip –

You can run the Java ES installer without installing software. This is useful for creating state files for a silent installation or for surveying Java ES software on your existing hosts.


Language Selection

The interactive installer runs in the language specified by the operating system locale setting. The following languages are available:

If your operating system language is not listed, the installer runs in English.

The installer automatically installs English versions of all Java ES components. In addition, you can choose to install component packages in any of the languages listed. During an installation session, the language you choose applies to all the components you are installing. To install some components in one language and other components in another language, you must run the installer multiple times.

On Solaris OS, if your operating system language is on the list, that language is automatically selected for component installation. However, you can change this selection.

The Java ES installer cannot install additional language packages for previously-installed components. However, you can use the pkgadd or rpm utility to add language packages at any time.

Preexisting Component Check

During installation, the Java ES installer surveys the software that is already installed on the host where you are installing and identifies the following:

Dependency Check

Many components depend on the presence of other components to provide their core functions. The installer does extensive cross checking of components to verify that the components you select during installation will function properly together. For this reason, the installer might prompt you to include certain components as you make your component selections.

In general, the Java ES installer uses the following rules for handling dependencies among the Java ES components:

Configuration Options and Parameter Settings

Many Java ES component products require some degree of installation-time configuration. The extent of installation-time configuration you perform depends on which components you select and which installation option you choose.

The following configuration options are available in the installer:

Common server settings are parameters that multiple components use. For example, most components require that you specify an administrative ID and password. By setting these common values, you are setting default values for all component administrative IDs and passwords. Component settings are parameters that apply to a particular component. These settings are requested during installation only if you have selected the Configure Now option. Some of these settings are populated from the common server settings.

Uninstaller

Java ES provides an uninstallation program for removing component products that were installed on your local host using the Java ES installer. The Java ES uninstaller checks product dependencies for the host on which it is running, issuing warnings when it discovers a dependency.

The uninstaller can be run in graphical, text-based, or silent mode.

After Java ES installation is complete, the uninstaller is located here:
