About Add-on Components

Enterprise Server is designed to provide its functionality in a modular form so that you can choose to include the functionality that you need and leave out the functionality that is not needed. OSGi modules, also called bundles, provide add-on functionality for your deployed Enterprise Server. You can add or remove an add-on component during runtime, with no need to restart the server.

Over time, new add-on components will be developed and existing components will be modified. Enterprise Server provides a set of image packaging system (IPS) tools for updating software on a deployed server. You can install new or updated add-on components by using the Update Tool in the following ways:

• As a selection in the graphical Enterprise Server Administration Console

• As a standalone graphical tool which can be started from the command line using the following format: as-install-parent/bin/updatetool

• As a command-line utility (the pkg command) which can perform most of the tasks offered by the graphical Update Tool. The main reasons for using the pkg command are:

  • As a basis for creating update scripts

  • As a method for working with systems that do not have a monitor, graphic card, or keyboard (headless systems)

Extensive online help is provided for both graphical versions.
