Service Broker教程 - 一台机器上有两个SQL Server实例。如何路由？

Question

我正在关注MSDN的Completing a Conversation Between Instances教程。该Lesson 2: Creating the Initiator Database（末）显示，如何在引发位点创建航线（缩短）：

... 
USE InstInitiatorDB; 
CREATE ROUTE InstTargetRoute 
WITH SERVICE_NAME = 
     N'//TgtDB/2InstSample/TargetService', 
    ADDRESS = N'TCP://MyTargetComputer:4022'; 

... 

USE msdb; 
CREATE ROUTE InstInitiatorRoute 
WITH SERVICE_NAME = 
     N'//InstDB/2InstSample/InitiatorService', 
    ADDRESS = N'LOCAL' 

和Lesson 3: Completing the Target Conversation Objects确实目标实例相同：

USE InstTargetDB; 
CREATE ROUTE InstInitiatorRoute 
WITH SERVICE_NAME = 
     N'//InstDB/2InstSample/InitiatorService', 
    ADDRESS = N'TCP://MyInitiatorComputer:4022'; 

... 

USE msdb 
CREATE ROUTE InstTargetRoute 
WITH SERVICE_NAME = 
     N'//TgtDB/2InstSample/TargetService', 
    ADDRESS = N'LOCAL'; 

然而，教程假设SQL服务器实例在单独的硬件上运行。如果两台SQL服务器实例在同一台计算机上运行，​​我应该如何更改路由或其他什么？

Answer 1

这两个实例不能共享侦听器端口。在第1课，你有这样的：

... 
CREATE ENDPOINT InstTargetEndpoint 
STATE = STARTED 
AS TCP (LISTENER_PORT = 4022) 
... 

和第2课，你有这样的：

... 
CREATE ENDPOINT InstInitiatorEndpoint 
STATE = STARTED 
AS TCP (LISTENER_PORT = 4022) 
... 

既是实例被配置为侦听同一TCP端口上这是行不通的。必须有所不同。让我们使目标监听4023：

... 
CREATE ENDPOINT InstTargetEndpoint 
STATE = STARTED 
AS TCP (LISTENER_PORT = 4023) 
... 

然后从发起到目标的路线具有指定端口现在4023：

... 
CREATE ROUTE InstTargetRoute 
WITH SERVICE_NAME = 
     N''//TgtDB/2InstSample/TargetService'', 
    ADDRESS = N''TCP://MyTargetComputer:4023'';'; 
... 

其他一切保持不变。
