Managing scheduled tasks

To view all scheduled tasks in BIRT Analytics, choose Workflow—Tasks and events—Scheduled tasks. Scheduled tasks appear, sorted by creation date and time in ascending order. A selected task appears highlighted in blue, as shown in Figure 8-9.

Selecting one scheduled task

Use Scheduled tasks to complete any of the following activities:

To view current status of all scheduled tasks, choose Refresh.

To create a new scheduled task having no properties, choose Create.

To create a new scheduled task having the same properties as an existing one, select a task and choose Duplicate.

To edit an existing scheduled task, select a scheduled task and choose Modify.

To remove a scheduled task from BIRT Analytics, choose Delete.

To view a list of scheduled tasks already completed, choose Executions.

Duplicating a scheduled task

Duplicate creates a new scheduled task having all properties of an existing, selected task. Duplicating a scheduled task, then modifying one or multiple properties in the duplicated task, saves time spent recreating identical properties for a new task. Only the time attribute, indicating the time at which a task is created, is unique for a new, duplicate task.

How to duplicate a scheduled task

1	In Scheduled tasks, select a task.

2	Choose Duplicate.

3	In Scheduled task detail, choose Save.

A new task having all properties of the original task appears in Scheduled tasks. The new task has a unique value in Time, as shown in Figure 8-10.

Modifying a scheduled task

You can modify properties of an existing, scheduled task before the time or event set as a trigger for that task occurs. Scheduled task details supports editing and saving changes to task properties.

How to modify a scheduled task

1	In Scheduled tasks, select a task from the list.

2	Choose Modify.

3	Using Scheduled task details, change at least one property of the task. For example, edit the name property.

4	Choose Save.

Using a conditional query to automate actions

Action properties support associating specific actions with defined trigger event conditions. Automating a notification process provides a basic example for associating event-triggered, scheduled tasks and unique trigger events. A basic example demonstrating how to define unique actions that result from evaluating a conditional query follows.

The following example task generates one of two unique email message actions based on evaluating an order quantity in a customer database.

How to specify actions based on query results

1	In a scheduled task, create an event trigger having conditions that monitor the customer order table:

1	In Trigger for task, expand BIRT Analytics. Then drag and drop an Engineering event type in the scheduled task editor.

2	In Scheduled task detail—Scheduled task, define conditions and attributes that identify a specific column, as shown in Figure 8-11.

Figure 8-11

Defining specific conditions for a scheduled task

2	In Actions for the event-triggered task, expand Conditional. Drag Query and drop it in the visual editor, as shown in Figure 8-12.

Creating a Query action for a scheduled task

3	Specify query conditions for an action using Action details. For example, the selections shown in Figure 8-13 compare a quantity in a specific field with a defined value. The result returned by the conditional query is Yes or No.

Specifying query conditions for an action

4	In Actions, add two Send email actions, using the visual editor, as follows:

1	Expand Sending. Drag and drop a Send email action on Query. Choose Yes.

2	Configure details for an email message action, appropriate for a Yes result.

3	Drag and drop another Send email action on Query. Choose No.

4	Configure details for an email message action, appropriate for a No result.

5	Two Send email actions appear, one for each query condition, as shown in Figure 8-14.
