Example of User-Defined Events

Say you have four sessions you want to run in a workflow. You want Q1_session and Q2_session to run concurrently to save time. You also want to run Q3_session after Q1_session completes. You want to run Q4_session only when Q1_session, Q2_session, and Q3_session complete.

The following workflow shows how to accomplish this using the Event-Raise and Event-Wait tasks:

To configure the workflow, complete the following steps:

Link Q1_session and Q2_session concurrently.

Add Q3_session after Q1_session.

Declare an event called Q1Q3_Complete in the Events tab of the workflow properties.

In the workspace, add an Event-Raise task after Q3_session.

Specify the Q1Q3_Complete event in the Event-Raise task properties. This allows the Event-Raise task to trigger the event when Q1_session and Q3_session complete.

Add an Event-Wait task after Q2_session.

Specify the Q1Q3_Complete event for the Event-Wait task.

Add Q4_session after the Event-Wait task. When the Integration Service processes the Event-Wait task, it waits until the Event-Raise task triggers Q1Q3_Complete before it runs Q4_session.

The Integration Service runs the workflow in the following order:

The Integration Service runs Q1_session and Q2_session concurrently.

When Q1_session completes, the Integration Service runs Q3_session.

The Integration Service finishes executing Q2_session.

The Event-Wait task waits for the Event-Raise task to trigger the event.

The Integration Service completes Q3_session.

The Event-Raise task triggers the event, Q1Q3_complete.

The Integration Service runs Q4_session because the event, Q1Q3_Complete, has been triggered.
