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

There is already a sample in it, it is easy to refer to the changeThird, Message Flow nodeMB There are a number of nodes that can interact with databases, including Filter , Compute , and dedicated database nodes, such as:Basically, you can manipulate the database by all the nodes that can set the "data source" inside the attribute. It is easy to use the appropriate ODBC data source na

After checking a lot of information, only the code in one status is triggered for notification broker, but for a function improvement, I need a method for obtaining multiple call statuses (outbound call, incoming call, and call ......) Because the program needs to be triggered proactively, registrynotifyapp is used as the active broker. After checking msdn, it finds that there is no excessive explanation on

Transmission protocol and Security control WebSphere Message Broker (for short message broker) is an enterprise-class consolidated middleware and service bus that provides extensive connectivity, including MQ, HTTP, FTP, Web services, CICS Dozens of different transmission modes and protocols. In terms of security, each protocol has its own user identity information transmission and processing methods. Bef

Event Notification is integrated into Service Broker. It can capture SQL events asynchronously in the SQL Server instance and route event messages to a specific queue. With minimal system overhead, you can track events that occur in SQL Server instances, for example, user logon, stored procedure compilation, permission modification, and object processing, such as Create/Alter/Drop events for databases, assemblies, roles, or tables ). Unlike creating y

This demonstrates asynchronous messaging based on Service Broker between different databases in the same SQL Server, where stored procedure serves as the service program. HELLOWORLDDB is the target database, and DOTNETFUN2 is the database that sent the message. Also, assume that the base object type of server broker has been created, such as MessageType (Xmlmessage), Contract (Xmlcontract), Queue (Sendingq

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

For example, there are more than 1000 Li on the top of the click event, if you traverse the words can be very inefficient to use the event agent, the UL bound event to improve efficiency"UID"> "Li1">1"Li2">2"Li3">3"Li4">4"li5">5"Li6">6"Li7">7"Li8">8"Li9">9"li10">Ten... ..JS code about this.var uid = document.getElementById ("UID"); Uid.onclick = function (e) {e = e | | Window.event;var target = e.target | | e.srcele Ment;if (target.tagName.toLowerCase () = = = ' Li ') {alert (target.innerhtml);}
