By default, the COM+ Event Service can only deliver notifications if a subscriber is available immediately or can be created on the fly. In many situations, subscribers might be programs running on other machines, and the life cycle of such subscribers is beyond the control of the Event Service. In these cases, COM+ supports queued components, which I ll describe in more detail in the next section, Microsoft MSMQ. Queued components are used in distributed systems and have two parts: a client side and a server side. Between them sits MSMQ, Microsoft s message queuing middleware. Figure 5-27 shows the parties involved with queued components. A queued component allows a publisher to send notifications to a remote subscriber, even if the subscriber is disconnected. MSMQ buffers notifications sent while the subscriber is offline. When the subscriber goes online, the server side of the queued component delivers the notifications stored in MSMQ. The whole process is essentially transparent to both the publisher and the subscriber. From the programmer s perspective, the only change necessary to support events with temporarily disconnected servers is to designate the event object (e.g., MyEvent, which implements IMyEventType) as a queued component. The COM+ infrastructure takes care of most of the plumbing details. By default, COM+ events do not support any QoS options: Delivery is always attempted, but only once. To support QoS, you must use queued components, offloading the QoS management on MSMQ. Implementing a system using COM+ events is fairly complicated from the programming perspective. The .NET Framework alleviates much of the pain by wrapping lower-level COM plumbing gunk in .NET classes. You can also handle many types of operations, such as managing subscribers, filters, and queued components, using a variety of administration tools.

In the mid-1990s, enterprise systems and directory services were hot topics, and many companies were scrambling to announce enterprise-level products of various kinds. Enterprise systems are about distributed computing, scalability, and reliability. Messaging is a pivotal component in the overall picture. MSMQ11 is Microsoft s enterprise-level message queuing service. Microsoft introduced MSMQ originally as part of a marketing effort that went by the unfortunate name DNA (Distributed interNet Applications). DNA included other technologies besides MSMQ, such as Distributed COM and Microsoft Transaction Server. You can use MSMQ in both single-server or distributed-server systems. In a single-server system, clients running on the server machine or on separate machines use message queues stored on the server machine. The collection of an MSMQ server and its clients is called a site. Figure 5-28 shows a site with three clients. All the machines of a site are typically in the same place, such as the same building or the same floor. The MSMQ server machine uses a local database to store site information such as configuration data, persistent messages, and administrative data. Machines in a site are presumed to have high-speed network connectivity with each other. Clients whose queues are stored on the server are called dependent clients, because they depend on a connection to the server to access their message queues. Clients are called independent if they have their own local message queues and can work while disconnected temporarily from the site server. Independent clients use a local MSMQ Queue Manager service on each client machine, as shown in Figure 5-29.

You need to execute the DBMS_REDEFINITION.COPY_TABLE_DEPENDENTS procedure next, to automatically create any existing triggers, indexes, grants, and constraints on the HR.EMPLOYEES_ TEMP table. Here s how you do it: SQL> DECLARE SQL> num_errors PLS_INTEGER; SQL> BEGIN DBMS_REDEFINITION.COPY_TABLE_DEPENDENTS('hr', 'employees', 'employees_temp', DBMS_RE DEFINITION.CONS_ORIG_PARAMS, TRUE, TRUE, TRUE, TRUE, num_errors); END;

Tip You can improve the performance of the redefinition process by running the redefinition job in parallel. To do this, you must first execute the following statements before executing the START_REDEF_TABLE procedure to start the table redefinition process:
