Enterprise Server provides an administrative tool called Update Tool that enables you to install updates and add-on components to your existing Enterprise Server installation.
Update Tool can be accessed as a standalone graphical tool from the command line (using the updatetool command from as-install-parent/bin), or as a browser-based graphical tool from the Administration Console (using the Update Tool node). For more information about Update Tool, see Update Tool in Oracle GlassFish Server 3.0.1 Administration Guide.
To update or remove installed components, you must use the standalone graphical Update Tool, not the Administration Console Update Tool.
A command-line interface is also available for Update Tool. This interface uses the pkg command and enables you to perform most of the tasks provided by the standalone graphical version. For more information about the pkg command, see Chapter 10, Extending GlassFish Server, in Oracle GlassFish Server 3.0.1 Administration Guide.
Update Tool differs from Upgrade Tool, which is used to migrate the configuration and deployed applications from an earlier version of GlassFish Server to the current version. For more information about Upgrade Tool and upgrading, see the Oracle GlassFish Server 3.0.1 Upgrade Guide.
