This section explains the structure of Location Awareness Services for WebSphere® Premises Server and
how to define it.
Figure 1 shows the structure of Location Awareness Services for WebSphere Premises Server and
how the topological items are related.
Figure 1. Structure of Location Awareness Services for WebSphere Premises Server
The following user interfaces
are provided with
Location Awareness Services for WebSphere Premises Server:
- Preferences Administration GUI
The Preferences Administration GUI allows
you to define areas and subareas and set preferences for those areas,
such as scaling and coordinate transformation values. You can also
define the SVG images for your areas.
- Spatial Management Client
The Spatial Management Client allows
you to define zones and provides a visualization of the defined topology
with the tags and their current positions. You can see if a tag has
violated a business rule. You can also search for items and request
reports.
There are two versions of the Spatial Management Client:
one that allows you to both define and delete zones and monitor tags,
and one that only allows you to monitor tags.
- Location Awareness Services for WebSphere Premises Server Administrative Console
The Location Awareness Services for WebSphere Premises Server Administrative Console is
based on WebSphere Application Server and
consists of portlets that allow you to define the topology of a location
where assets and personnel are tracked. You can use the portlets to
define the items, such as assets and personnel, and the rules that
control compliance with safety and security regulations. You can also
set or change Location Awareness Services for WebSphere Premises Server system
properties. Additional portlets are available to view, maintain, and
search events and also to generate and view reports on tag activity.
To define
Location Awareness Services for WebSphere Premises Server,
complete the following steps using the GUIs and
Location Awareness Services for WebSphere Premises Server Administrative Console:
- Define areas and subareas for the location. Do so by creating
scalable vector graphic (SVG) images of the areas that you want to
monitor and point to them in the Preferences Administration GUI.
Because the Spatial Management Client is
typically accessed through IBM® HTTP Server, store
the SVG images and item icons on the Location Awareness Services for WebSphere Premises Server on
which the IBM HTTP Server is
located.
- Define zones in the administration version of the Spatial Management Client.
Zones are related to the area in which they are created.
- Define the location topology in the Location Awareness Services for WebSphere Premises Server Administrative Console:
- Define the location event providers and associated devices:
- Define location event providers.
- Define devices per location event provider (if required).
- Define the registration units you want to use to define items.
- Define any boundary zones.
- Define gates.
- Define the item class hierarchy of items to be tracked, such as Person and Asset classes
in the Location Awareness Services for WebSphere Premises Server Administrative Console.
- Define the item groups to be used and the relationship between
the groups in the Location Awareness Services for WebSphere Premises Server Administrative Console.
- Register the items to be tracked by the system and the association
of items to classes and groups in the Location Awareness Services for WebSphere Premises Server Administrative Console.
- Define the business rules that determine the item tracking behavior
of the system in the Location Awareness Services for WebSphere Premises Server Administrative Console.
For example, you might define a rule that allows only those persons
belonging to a specific group, such as Security,
to enter a specific zone, such as HazardousZone.
You can also set system properties to determine the alert behavior
for other rules, such as a low battery threshold.
- Define the programs or web services to be called for filtered
alerts in the Location Awareness Services for WebSphere Premises Server Administrative Console.
For a predefined e-mail notification program, define who to notify
about alerts.
- Define the customized reports available for this installation.
