SCIM Level |
Description |
System |
System
is the top level of the SCIM hierarchy. A system represents a collection of components.
Each system has a unique identifier, which is used to designate that system throughout Tivoli
Problem Management. A personal computer and a benefits package are both examples of
systems. |
Component |
Component
is the second level of the SCIM hierarchy. Components are the basic building blocks of
systems. A component is a general category of devices, such as monitors, CPUs, and
printers. As with systems, components must have unique identifiers. A component, however,
can be used in the definition of more than one system. As you define the SCIM
hierarchy, do not refer to specific brands, versions, or models of products in the system
and component levels. For instance, "Monitor" is a valid component, but
"IBM P92 Monitor" is not. An IBM P92 is an actual monitor model, while
"Monitor" simply is a description of the device used to view the output of a
computer. In a similar vein, "Application" is a valid component because it
describes a concept and cannot be specifically purchased. "Tivoli Problem
Management," however, is not a component because you can actually purchase this
product from a vendor. Instead, specific products are defined at the item and module
levels. Monitors, computers, and printers can be components of a "personal
computer" system. |
Item |
Item
is the third level in the hierarchy. This level is where specific brands and models of
products are entered into the hierarchy. Each component can have any number of items. Each
item is one specific example of a component. For instance, a "Monitor" component
can categorize many items. Each of these items is a different type of monitor, such as
"IBM P92," "NEC 5-D," and so on.
Because the item level of the hierarchy specifies equipment that can be purchased, a
vendor can be associated with every item. |
Module |
Module
is the bottom level of the hierarchy. A module is a part of an item that can experience a
problem. Just as a system consists of components, each item can consist of several
modules. For example, a word processing application can be comprised of several modules:
graphics, printing, editing, and so on. These modules cannot be purchased separately.
Therefore, they are appropriately defined at the module level. |
