Example

For example, you have a Command task that depends on the status of the three sessions in the workflow. You want the Integration Service to run the Command task when any of the three sessions fails. To accomplish this, use a Decision task with the following decision condition:

$Q1_session.status = FAILED OR $Q2_session.status = FAILED OR $Q3_session.status = FAILED

You can then use the predefined condition variable in the input link condition of the Command task. Configure the input link with the following link condition:

$Decision.condition = True

The following figure shows a sample workflow using a Decision task:

The Decision task workflow contains a Start task, three sessions that link to a Decision task, and a Command task.

You can configure the same logic in the workflow without the Decision task. Without the Decision task, you need to use three link conditions and treat the input links to the Command task as OR links.

You can further expand the workflow. The Integration Service runs the Command task if any of the three Session tasks fails. Suppose now you want the Integration Service to also run an Email task if all three Session tasks succeed. To do this, add an Email task and use the decision condition variable in the link condition.

The following figure shows the expanded sample workflow using a Decision task:

The expanded Decision task sample workflow includes a Start task, three sessions, and a Decision task that links to a Command task or an Email task depending on the decision outcome.
