C # event 1, multicast Delegate 2, event 3, custom events in the previous chapter, all delegates supported only a single callback. However, a delegate variable can refer to a series of delegates, in which each delegate sequentially points to a subsequent delegate, forming a chain of delegates, or multicast delegate *multicast delegate. Using a multicast delegate, you can invoke a method chain through a method object, create a variable to reference the method chain, and pass those data types as p

Replication Monitor operation has three operations: reinitialize Subscriptions,validate replicated Data and Subscription expiration and Dea Ctivation1,reinitialize SubscriptionsReinitialize a subscription refers to making a subscription for reinitialization after subscription is created, or the Requires a reinitialization, the subscription is reinitialized to ensure that the data and schema of publication and subscription are the same.Description of the MSDN Initialize a Subscription:Subscribers

implementation of the changes, directly to a lot of external interface name to get rid of, why?The benefits of Eventbus are obvious, completely decoupling the relationship between the request chain, to avoid the requestor is long held, and more than the broadcast lighter, more powerful than Localbroadcast, the interface is simple and practical. Shortcomings, such as the definition of various events is a workload.SOURCE Analysis-Registration (register)EventBus.java:privatesynchronizedvoidregiste

Replication not only pushes the table article or SP article to the subscription, but also pushes the execution of the SP to subscription. The execution of the push SP refers to pushing the command of the executing SP to subscriber to execute, rather than pushing a large amount of transaction generated after the SP execution to Subscriber. Transaction is to update data rows in table article one at a.Push the

to store data sent from the forwarding publisher. A Distributor supports multiple publishers, just as a newsstand can sell magazines from multiple publishers. Similarly, the distributor can be the same instance as the Publisher, as publishers do not sell their magazines directly through newsstand. Subscriber server The subscriber in Figure 2 contains a copy of the data published by the publisher. This copy

Background (contexts) There is a database task in Server A that requires some of the table partial fields to be published and subscribed to Server B's Tasksiteinfo database, but a server is a bit special because it has a named instance in addition to the default instance: TZR06\SQLSERVER2008R2, If it i

Classes or objects can notify you of events that occur when other classes or objects are concerned. The class that sends (or raises) an event is called the publisher, and the class that receives (or handles) the event is called a Subscriber. Events Overview Events have the following characteristics: L The Publisher determines when an event is raised and the Subscriber determines what action is taken

/subscribe pattern is one of the messaging applications in which the relationship between the publisher of the message and the Subscriber to the message is loosely coupled. In a publish/subscribe system, the Publisher does not need to know who will use the information it provides, and the Subscriber does not need to know who is providing the source of information it needs. In contrast to other application p

SQL Server 2000 provides more replication options than previous versions, including immediate updating of subscribers, queued updating, queued updating as an immediate update to hot backup, transfer of replicated data, filtered publication data, and more. The first three options indicate that the copied data can be modified at the Subscriber, and then the modifications are reflected in the appropriate way to the publisher. If these replication options

Create a new sample database Cnblogsdemo in the primary database server CNBlogsDB1 (Note Recovery mode uses the default value of full, which is the only mode for transactional replication), and then creates a test table, such as Cnblogstest. 2.
