Java programs can be delivered as applets that require a Web browser to<br />

download the executable code or as stand-alone applications that are stored<br />

locally and run independently of a browser or viewer.<br />

Web-Based System Manager has been packaged in a browser-based applet<br />

mode, and for local execution, an application mode has been implemented. The<br />

application mode uses the <strong>AIX</strong> Java Virtual-Machine that, in turn, executes the<br />

Java applications as threads on the system.<br />

Note: When referring to Java applications, the term application is used differently<br />

than the conventional use of application as in word processing application or in<br />

the discussion on application-oriented user interfaces below. Java application<br />

refers to the manner in which Java code is invoked.<br />

6.2.1 Web-Based System Manager Components<br />

Web-Based System Manager includes the following components:<br />

• Backups<br />

• Devices<br />

• File Systems<br />

• Network (interfaces for configuring network communications)<br />

• Printer Queues<br />

• Processes<br />

• Registered Applications<br />

• Software (installable software, software installed, and objects related to<br />

installation)<br />

• Subsystems<br />

• System (user interface, console, date/time, language, OS characteristics,<br />

system logs, and dump devices)<br />

• Users<br />

• Volumes<br />

6.2.2 Web-Based System Manager User Interface<br />

The Web-Based System Manager user interface is an Object-Oriented User<br />

Interface (OOUI). OOUIs are distinguished from traditional, application-oriented<br />

user interfaces, in that the user focuses on readily identifiable things on which the<br />

user works. In an application-oriented environment, the user focuses on a tool for<br />

manipulating the work. Some examples may clarify the distinction. In a document<br />

processing context with an application-oriented interface, the user focuses on the<br />

tool (a word processing program). While in OOUI, the user focuses on the object<br />

of the task itself (the document). In a system management context, an<br />

application-oriented interface would require the user to learn management tools<br />

(for example, a Print Manager application), while an OOUI would enable the user<br />

to directly manipulate a representation of the managed object (for example, a<br />

printer or group of printers).<br />

In the evolution of <strong>AIX</strong> system management user interfaces, SMIT was an<br />

application-oriented interface, and VSM was a mixed application/object-oriented<br />
