Oracle 11g Dataguard Snapshot standby database functionality, which places the standby in open read/write state and simulates the test in the main library of the production environment. When the standby snapshot standby task completes, you can switch back to the physical repository role. In the state of snapshot standby database, the repository can accept the log from the main library, but it cannot apply the change to the repository. This article uses Oracle 11g Dataguard

the broker mode:1, proper use of the mediator pattern avoids over-coupling between colleague classes, making it possible to use the peer classes relatively independently.2, using the mediator pattern can transform one-to-many associations between objects into one-to-one associations, making relationships between objects easy to understand and maintain.3, the use of the mediator mode can be the object's behavior and collaboration to abstract, can be m

This article outlines how to take advantage of the new Service Broker features in SQL Server 2005 to speed up and simplify the development of SQL Server applications based on asynchronous queued operations. (Note that in the sample file, the programmer's comment is in English, which is translated into Chinese for easy Reader's understanding.) ） First, the introduction One of the major achievements of SQL Server 2005 is the ability to implement reliabl

With the event proxy, you can bind the event handler to the parent element, avoiding the addition of the event handler to multiple child elements. To optimize performance.Event bubbles and target elements are used by the events agent. The target element of any element is the first element. The first thing to notice here is the difference between the target of the event and the currenttarget .Target: Represents the element that triggered the event. currenttarget: The element that represents the e
