COM+ can also manage transactions. Transactions can span methods, components, databases, and even servers running database products from different vendors. All code enlisted in the transaction gets to vote on the outcome of the transaction. It s more like veto power though, because any vote of no causes the entire transaction to be rolled back. Each class configured in COM+ sets an attribute determining its transactional behavior. This attribute is designed so that a transaction can be dynamically composed of many different components, in a way that may not be known when the autonomous components are designed. Table 7-4 is a summary of the options for transactional behavior.

3. The DoWork event handler is executed in the worker thread and computes the 1000th Fibonacci number. At the end of the computation, the result is written into args.Result, a mutable storage location in the event arguments for the DoWork event. The DoWork event handler then completes. 4. At some point after the DoWork event handler completes, the RunWorkerCompleted event is automatically raised on the main application thread. This displays a message box with the result of the computation, retrieved from the args field of the event arguments.

COM+ will create a new transaction if none exists, or the object will be enlisted in the transaction of the object that created it. COM+ will create a brand new transaction. The object will not participate in the transaction of its creator, if one exists. The object will be enlisted in the transactional support of the creating object (if it has any) or else will run without a transaction. This is the default. The object does not care about, and does not participate in, any transactions. This is like Does Not Support, but it requires no COM+ context. This choice is nearly equivalent to a nonconfigured component.

for x in ( select p.* from components_nt c, TABLE (c.parts) p where p.part_id = i ) loop l_x := l_x + 1; end loop; end loop; dbms_output.put_line( l_x ); end do_nt_select;

Starts the process on a separate thread asynchronously. Called from the main thread. Set the CancellationPending flag of the background task. Called from the main thread. Set to true by raising CancelAsync. Used by the worker thread. Set to true if the worker can support progress updates. Used by the main thread. Set to true if the worker can support cancellation of the current task in progress. Used by the main thread. Indicate the progress of the operation. Used by the worker thread. Fires in response to a call to RunWorkerAsync. Invoked on the worker thread. Fires when the background operation is canceled, when the operation is completed, or when an exception is thrown. Invoked on the main thread. Fires whenever the ReportProgress property is set. Invoked on the main thread.
