In general, you are installing the basic components that provide the functionality of the Application Server product. You can choose not to install some of the components. Later, if you want to add a component that you initially chose not to install, you can do an incremental installation of that component, providing dependencies are met.
A partial installation can be followed by any number of incremental installations. For silent mode, you can do a partial initial installation, but any subsequent installations must be done using an interactive method.
The installation program enforces component dependencies as specified for each component. Once component dependencies are satisfied, component life cycles are independent. A particular component can be installed dynamically through incremental installation without corrupting other components. However, partial uninstallation is not supported.
The following installation components are included with the Application Server Enterprise Edition product:
Application Server—Application Server software, including its command-line administrative tools, and Sun JavaTM System Message Queue software.
Select the Administration Client component to install the command-line utility separately on a machine where the Application Server is not installed. When you install the Application Server or the Domain Administration Server, the Administration Client is also installed.
Java 2 Software Development Kit—During installation, you can choose to reuse a Java 2 SDK that is already installed on your system as long as the Java 2 SDK version is correct. The default installation location for each distribution is install_dir/jdk.
Refer to the Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Update 2 Release Notes to identify which version of the Java 2 SDK is supported.
The Sun Java System Application Server product is certified to work with Java 2 SDK from Sun Microsystems. Third-party Java development kits, even with appropriate version numbers, are not supported.
PointBase database server.
Sample applications—samples come with the source, schema, Ant build scripts, and EAR files. Any existing data associated with the database-related samples is available in the database. These sample applications are categorized as:
Technology samples—Introduce various technical aspects of the Java 2 Platform, Enterprise Edition (J2EETM) specification as well as the value added features of the Application Server platform.
Interoperability samples—Provide more detailed views on how these technologies come together on the Application Server platform.
By default, the sample applications are installed at: install_dir/samples.
More information about samples at: install_dir/samples/index.html.
The following additional components are included with the Application Server product:
To install the Application Server and an HADB server node on the same system, select both components.
