6.3 Workspaces and links

The use of IBM Tivoli OMEGAMON XE solutions with the Tivoli Enterprise Portal

user interface can entail reviewing information from multiple systems,

subsystems, and components. This may require you to access information from

multiple workspaces, which can be achieved with ease-of-use navigational aids

provided by Tivoli Enterprise Portal, using the ability to link workspaces.

IBM Tivoli OMEGAMON XE has many product-provided links to assist with

navigation among the product-provided workspaces. You can define more links

between your custom workspaces and the product-provided workspaces.

6.3.1 Linking overview

Links are saved as part of the workspace for which they are created. Links can

span applications, logical views, and attribute groups. That is, you can link any

workspaces regardless of their inherent relationship or apparent lack of

relationship.

Tivoli Enterprise Portal provides two general types of links: simple and advanced.

򐂰 A simple link is a shortcut from one workspace to another that does not

explicitly pass data from the source workspace to a target workspace. That is,

simple links are like hyperlinks on Web pages that provide navigation from

one page to another or from one Web site to another.

򐂰 An advanced link explicitly affects the data that is displayed on the target

workspace. Advanced links pass filtering data to the target workspace. When

executing an advance link, data from the link source is passed to the target

workspace query or queries. The target workspace’s queries will filter the

information and only return information that satisfies passed variables.

There is another aspect of defining a link. A link can be relative or absolute.

򐂰 Absolute link: Most user-defined links are absolute links. When you define an

absolute link, you specify one specific workspace as the target workspace.

Absolute links enable you to link to differnt levels in the Navigation tree.

򐂰 Relative link: Many product-provided links use relative links since host names

are not known when the link is defined. When a relative link is executed,

multiple target workspaces may match the target criteria. In this scenario, a

menu is displayed from which the user selects the desired target. When a

relative link links from a lower Navigator tree level to a higher level, there is no

ambiguity and only one item satisfies the target criteria.

Figure 6-3 shows an example of links provided by IBM Tivoli OMEGAMON XE.

Notice that all existing links, as well as the Link Wizard and Link Anchor facilities,

are available from pop-ups. Also notice that when the link source is a tabular

view, the link symbol is inserted to the left of the data rows.
