When your application is running, you should validate its fault-tolerant operation and
reliance upon TMF. This might entail a recovery drill where operators use TMF to

Example Following is an example of how UOWs might flow in a Queue Manager application.
The example represents part of a retail application similar to the one illustrated in
Figure 1-7 in Section 1, “Introduction to Queue Manager.” In this application,
Inventory Control awaits a sales order from Sales. When it arrives, Inventory Control
issues a purchase order to Purchasing. Purchasing accepts the purchase order and
issues a purchase order number to Inventory Control.
The application starts processing when a salesperson enters a sale at a terminal. It
completes when Inventory Control gets a purchase order number for the item sold.
