浅述远程Service Broker的实现

上文SQL Server 2008中Service Broker基础应用(上)、SQL Server 2008中Service Broker基础应用(下)演示了在同一个SQL Server实例的不同数据库之间实现Service Broker，其实，更常见的是在不同的SQL Server实例之间进行通信，本文将通过实例演示如何进行Service Broker远程通信。

以下是实现远程Service Broker的基本步骤：

一、启用传输安全

二、启用对话安全

三、创建路由

四、创建远程服务绑定

下图显示的是两个 SQL Server 实例间的 Service Broker 网络通信的高级视图。

准备工作：

/************************************************************/
------远程Service Broker
------ [email protected]
-----源服务器实例,在本例中为ap4\agronet09
USE master
GO
-- Enable Service Broker for the database
ALTERDATABASE BookStore SET ENABLE_BROKER
GO
ALTERDATABASE BookStore SET TRUSTWORTHY ON
GO

USE BookStore
GO
-- Create the messages
CREATE MESSAGE TYPE [//SackConsulting/SendBookOrder]
VALIDATION = WELL_FORMED_XML
GO
CREATE MESSAGE TYPE [//SackConsulting/BookOrderReceived]
VALIDATION = WELL_FORMED_XML
GO

-- Create the contract
CREATE CONTRACT
[//SackConsulting/BookOrderContract]
( [//SackConsulting/SendBookOrder]
SENT BY INITIATOR,
[//SackConsulting/BookOrderReceived]
SENT BY TARGET
)
GO

-- Create the queue
CREATE QUEUE BookStoreQueue
WITH STATUS=ON
GO

-- Create the service
CREATE SERVICE [//SackConsulting/BookOrderService]
ON QUEUE dbo.BookStoreQueue
([//SackConsulting/BookOrderContract])
GO

-----目标服务器实例,在本例中为ap2\agronetserver
USE master
GO
IFNOTEXISTS (SELECT name
FROM sys.databases
WHERE name ='BookDistribution')
CREATEDATABASE BookDistribution
GO

-- Enable Service Broker for the database
ALTERDATABASE BookDistribution SET ENABLE_BROKER
GO
ALTERDATABASE BookDistribution SET TRUSTWORTHY ON
GO

USE BookDistribution
GO
-- Create the messages
CREATE MESSAGE TYPE [//SackConsulting/SendBookOrder]
VALIDATION = WELL_FORMED_XML
GO
CREATE MESSAGE TYPE [//SackConsulting/BookOrderReceived]
VALIDATION = WELL_FORMED_XML
GO

-- Create the contract
CREATE CONTRACT
[//SackConsulting/BookOrderContract]
( [//SackConsulting/SendBookOrder]
SENT BY INITIATOR,
[//SackConsulting/BookOrderReceived]
SENT BY TARGET
)
GO

-- Create the queue
CREATE QUEUE BookDistributionQueue
WITH STATUS=ON
GO

-- Create the service
CREATE SERVICE [//SackConsulting/BookDistributionService]
ON QUEUE dbo.BookDistributionQueue
([//SackConsulting/BookOrderContract])
GO

一、启用传输安全

在Service Broker的安全传输，是指两个SQL Server实例之间进行网络连接时，启用或限制它们之间的加密通信。传输安全是在SQL Server实例级别，因此这个示例演示如何创建在两个SQL Server实例的主数据库对象。您可以选择两种形式的运输安全：Windows身份验证或基于证书的安全认证。

-- Enabling Transport Security

-- 在源实例上执行 Ap4\agronet09
USE master
GO
CREATE MASTER KEY ENCRYPTION BY PASSWORD ='1294934A!'

-- 在目标实例上执行 Ap2\agronetserver
USE master
GO
CREATE MASTER KEY ENCRYPTION BY PASSWORD ='1294934B!'

-- 在源实例上执行 Ap4\agronet09
CREATE CERTIFICATE AP4MasterCert
WITH SUBJECT ='Ap4 Transport Security SB',
EXPIRY_DATE ='5/4/2012'
GO

-- 在目标实例上执行 Ap2\agronetserver
CREATE CERTIFICATE AP2MasterCert
WITH SUBJECT ='AP2 Transport Security SB',
EXPIRY_DATE ='5/4/2012'
GO

-- 在源实例上执行 Ap4\agronet09
BACKUP CERTIFICATE AP4MasterCert
TOFILE='H:\SqlBackup\AP4MasterCert.cer'
GO

-- 在目标实例上执行 Ap2\agronetserver
BACKUP CERTIFICATE AP2MasterCert
TOFILE='H:\SqlBackup\AP2MasterCert.cer'
GO

-- 在源实例上执行 Ap4\agronet09
CREATE ENDPOINT SB_AP4_Endpoint
STATE = STARTED
AS TCP
(LISTENER_PORT =4020)
FOR SERVICE_BROKER
(AUTHENTICATION = CERTIFICATE AP4MasterCert,
ENCRYPTION = REQUIRED)
GO

-- 在目标实例上执行 Ap2\agronetserver
CREATE ENDPOINT SB_AP2_Endpoint
STATE = STARTED
AS TCP
(LISTENER_PORT =4021)
FOR SERVICE_BROKER
(AUTHENTICATION = CERTIFICATE AP2MasterCert,
ENCRYPTION = REQUIRED)
GO

-- 在源实例上执行 Ap4\agronet09
CREATE LOGIN SBLogin
WITH PASSWORD ='Used4TransSec'
GO
CREATEUSER SBUser
FOR LOGIN SBLogin
GO

-- 在目标实例上执行 Ap2\agronetserver
CREATE LOGIN SBLogin
WITH PASSWORD ='Used4TransSec'
GO
CREATEUSER SBUser
FOR LOGIN SBLogin
GO

-- 在源实例上执行 Ap4\agronet09
GRANT CONNECT ON Endpoint::SB_AP4_Endpoint TO SBLogin
GO

-- 在目标实例上执行 Ap2\agronetserver
GRANT CONNECT ON Endpoint::SB_AP2_Endpoint TO SBLogin
GO

----在源实例上执行 Ap4\agronet09
----需要从AP2上复制到AP4下H:\SqlBackup,邀月注
CREATE CERTIFICATE AP2MasterCert
AUTHORIZATION SBUser
FROMFILE='H:\SqlBackup\AP2MasterCert.cer'
GO

---- 在目标实例上执行 Ap2\agronetserver
----需要从AP4上复制到AP2下H:\SqlBackup，邀月注
CREATE CERTIFICATE AP4MasterCert
AUTHORIZATION SBUser
FROMFILE='H:\SqlBackup\AP4MasterCert.cer'
GO

二、启用对话安全

设置安全对话的详细用法，请参看MSDN:(http://msdn.microsoft.com/zh-cn/library/ms166036.aspx)。

/***********************************************************************/
-- Enabling Dialog Security

-- 在源实例上执行 Ap4\agronet09
USE BookStore
GO

CREATE MASTER KEY ENCRYPTION BY PASSWORD ='1294934A!'
GO

CREATE CERTIFICATE BookStoreCert
WITH SUBJECT ='BookStore SB cert',
EXPIRY_DATE ='5/4/2012'
GO

-- 在目标实例上执行 Ap2\agronetserver
USE BookDistribution
GO

CREATE MASTER KEY ENCRYPTION BY PASSWORD ='1294934B!'
GO
CREATE CERTIFICATE BookDistributionCert
WITH SUBJECT ='BookDistributionCert SB cert',
EXPIRY_DATE ='5/4/2012'
GO

-- 在源实例上执行 Ap4\agronet09
USE BookStore
GO
BACKUP CERTIFICATE BookStoreCert
TOFILE='H:\SqlBackup\BookStoreCert.cer'
GO

-- 在目标实例上执行 Ap2\agronetserver
USE BookDistribution
GO
BACKUP CERTIFICATE BookDistributionCert
TOFILE='H:\SqlBackup\BookDistributionCert.cer'
GO

-- 在源实例上执行 Ap4\agronet09
USE BookStore
GO
CREATEUSER BookDistributionUser
WITHOUT LOGIN
GO

-- 在目标实例上执行 Ap2\agronetserver
USE BookDistribution
GO
CREATEUSER BookStoreUser
WITHOUT LOGIN
GO

-- 在源实例上执行 Ap4\agronet09
----需要从AP2上复制到AP4下H:\SqlBackup,邀月注
USE BookStore
GO
CREATE CERTIFICATE BookDistributionCert
AUTHORIZATION BookDistributionUser
FROMFILE='H:\SqlBackup\BookDistributionCert.cer'
GO

-- 在目标实例上执行 Ap2\agronetserver
----需要从AP4上复制到AP2下H:\SqlBackup，邀月注
USE BookDistribution
GO
CREATE CERTIFICATE BookStoreCert
AUTHORIZATION BookStoreUser
FROMFILE='H:\SqlBackup\BookStoreCert.cer'
GO

-- 在源实例上执行 Ap4\agronet09
USE BookStore
GO
GRANT SEND ON
SERVICE::[//SackConsulting/BookOrderService]TO BookDistributionUser
GO

-- 在目标实例上执行 Ap2\agronetserver
USE BookDistribution
GO
GRANT SEND ON
SERVICE::[//SackConsulting/BookDistributionService]
TO BookStoreUser

三、创建路由

使用命令：CREATE ROUTE(http://msdn.microsoft.com/en-us/library/ms186742.aspx)创建路由

/************************创建路由 [email protected]****************/
-- 在源实例上执行 Ap4\agronet09
USE BookStore
GO
CREATE ROUTE Route_BookDistribution
WITH SERVICE_NAME ='//SackConsulting/BookDistributionService',
ADDRESS ='TCP://192.168.1.99:4021'
GO

-- 在目标实例上执行 Ap2\agronetserver
USE BookDistribution
GO
----SERVICE BROKER 609
CREATE ROUTE Route_BookStore
WITH SERVICE_NAME ='//SackConsulting/BookOrderService',
ADDRESS ='TCP://192.168.1.6:4020'
GO

四、创建远程服务绑定

使用命令：CREATE REMOTE SERVICE BINDING(http://msdn.microsoft.com/en-us/library/ms178024.aspx)创建远程服务绑定

/*********************创建远程服务绑定 [email protected] ***********/
-- 在源实例上执行 Ap4\agronet09
USE BookStore
GO
CREATE REMOTE SERVICE BINDING BookDistributionBinding
TO SERVICE '//SackConsulting/BookDistributionService'
WITHUSER= BookDistributionUser
GO

-- 在目标实例上执行 Ap2\agronetserver
USE BookDistribution
GO
CREATE REMOTE SERVICE BINDING BookStoreBinding
TO SERVICE '//SackConsulting/BookOrderService'
WITHUSER= BookStoreUser
GO

-- 在源实例上执行 Ap4\agronet09
Use BookStore
GO
DECLARE@Conv_Handleruniqueidentifier
DECLARE@OrderMsg xml;

BEGIN DIALOG CONVERSATION @Conv_Handler
FROM SERVICE [//SackConsulting/BookOrderService]
TO SERVICE '//SackConsulting/BookDistributionService'
ON CONTRACT [//SackConsulting/BookOrderContract];

SET@OrderMsg=
'<order id="3439" customer="22" orderdate="9/25/2008">
<LineItem ItemNumber="22" ISBN="1-59059-592-0" Quantity="10" />
</order>';

SEND ON CONVERSATION @Conv_Handler
MESSAGE TYPE [//SackConsulting/SendBookOrder]
(@OrderMsg);

查看结果：

-- 在目标实例上执行 Ap2\agronetserver

USE BookDistribution
GO
SELECT message_type_name, CAST(message_body as xml) message,
queuing_order, conversation_handle, conversation_group_id
FROM dbo.BookDistributionQueue
