Display event template details

To display an event template, click View Template Properties in the

corresponding table row. The Event Template Detail page displays as shown in

Figure 7-34.

Update event template data

You can update all event template data except the Event Template Name. You

can associate the event template with the predefined output channels or with

new ones you created to communicate task event messages between the

Premises Server, Edge Controller, and the enterprise.

We recommend that you do not update the predefined event templates.

Delete event templates

You can delete an event template at any time. You do not have to remove the

output channel associations first.

We recommend that you do not delete the predefined event templates.

7.5.3 Tasks (event handlers)

A task is a piece of software, or event handler, for coordinating the

communication of an event between an Edge Controller, Premises Server, and

enterprise system. For example, the Dock Door Receiving Event Handler directs

the delivery of tag information received from the Edge Controller to the Premises

Server and out to the enterprise.

178 IBM WebSphere RFID Handbook: A Solution Guide

By default, the Premises Server includes many predefined tasks:

򐂰 Alert Logger

򐂰 Heartbeat Logger

򐂰 Tag Read Event Handler

򐂰 Started Stopped Reading Event Handler

򐂰 External Validation Response Handler

򐂰 Start Stop Reading Command Handler

򐂰 Dock Door Receiving Event Handler

򐂰 Dock Door Receiving Response Handler

These tasks are used in the Premises Server internal processing and the Dock

Door Receiving scenario. We recommend that you do not change or delete them.

If you are extending your Event Server architecture, you might have additional

event handlers. This type of custom code is written typically by people who are

helping you to customize your RFID solution, delivered as message-driven

beans, and deployed on WebSphere Application Server. In these cases, you

need to create new task definitions for any of these custom tasks or event

handlers.

To work with tasks, click Tasks in the Administrative Console navigation frame.

The Tasks page displays as shown in Figure 7-35.

The Tasks page lists all the defined tasks and their descriptions.

Figure 7-36 Create new Task

2. Enter a unique Task ID and Description.

Select the events that this task handles from the list of Available Events, and

then click the right-arrow, , to add them to the list of Selected Events. For

multiple events, you must add them one at a time. Use the left arrow, , to

remove an event from the list of Selected Events.

3. When done, click Create.

Display, update, and delete tasks

You can display a task definition to review, update, or delete it.

Note: The task identifier must match the naming in the message-driven

bean deployment descriptor for this event handler. Consult with the

provider of this custom code.

Note: We recommend that you do not update or delete the predefined tasks. If

you do, the product scenarios (Dock Door and Print, Verify, Ship) might not

work as expected.
