Understanding Service Broker

Service Broker is a messaging system built in SQL Server that facilitates communication between different databases, services, and applications. It enables asynchronous, reliable messaging by providing sender and receiver services that can be used to transmit data and messages between different endpoints.

With Service Broker, developers can create applications that communicate with each other in a loosely-coupled and decoupled manner. This means that even if one application is down or busy, the other applications can still continue to function and interact with other components of the system.

Service Broker is particularly useful for large, distributed systems that are spread over multiple servers, because it allows communication between different parts of the system without relying on external messaging systems. By using Service Broker, developers can reduce the complexity of their systems and improve reliability, scalability, and performance.

To use Service Broker, developers must first create a conversation group, which is a set of related conversations between a sender and one or more receivers. Once a conversation group has been established, messages can be sent between the sender and receiver, allowing communication to take place.

Overall, Service Broker is an essential tool for anyone working with SQL Server who needs to implement messaging and communication between different parts of a system. With Service Broker, developers can create more robust, scalable, and reliable applications that can communicate asynchronously and without the need for external messaging systems.

Setting Up Service Broker

in SQL Server is a critical step towards implementing messaging and queuing capabilities within your system. This subtopic will provide an overview of the steps required to set up Service Broker, along with some sample code snippets to help you get started.

Here are the basic steps required to set up Service Broker in SQL Server:

  1. Enable Service Broker on your SQL Server database by running the following command:


  1. Create a new message type using the CREATE MESSAGE TYPE statement. This defines the format of the messages that will be sent and received through Service Broker.


  1. Create a contract using the CREATE CONTRACT statement to define the types of messages that can be exchanged between Services.


  1. Create a queue for incoming messages using the CREATE QUEUE statement.


  1. Create a service using the CREATE SERVICE statement. This defines the endpoint that Service Broker uses to receive and send messages.

CREATE SERVICE [ServiceName] ON QUEUE QueueName;

Now that we've outlined the basic steps required to set up Service Broker, let's take a look at some code snippets to help you get started. Here's an example of a CREATE MESSAGE TYPE statement:


This creates a new message type called StatusUpdate with XML validation.

Next, we'll create a contract for the StatusUpdate message type using the CREATE CONTRACT statement:

CREATE CONTRACT [StatusUpdateContract]

This defines a contract called StatusUpdateContract that allows an INITIATOR service to send messages of the StatusUpdate type.

Finally, we'll create a new queue and service for our StatusUpdate messages:

CREATE QUEUE [StatusUpdateQueue];

CREATE SERVICE [StatusUpdateService]
ON QUEUE [StatusUpdateQueue]

This creates a new queue called StatusUpdateQueue and a new service called StatusUpdateService that listens for messages on the queue using the StatusUpdateContract contract.

Overall, in SQL Server requires several logical steps, but it's a critical component of implementing messaging and queuing capabilities within your system. By following the steps above and using code snippets like those provided, you'll be well on your way to building more efficient and scalable applications with SQL Server.

Creating a Service Broker Application


To create a Service Broker application, you will need to follow these basic steps:

  1. Enable Service Broker: First, you need to enable Service Broker on your SQL Server instance by running the following command: "ALTER DATABASE [DatabaseName] SET ENABLE_BROKER;"

  2. Create a Message Type: Before you can send messages between services, you need to define the type of message you want to use. To do this, you need to create a message type using the following syntax: "CREATE MESSAGE TYPE [MessageType] VALIDATION = NONE;"

  3. Create a Contract: After you define your message type, you need to create a contract that specifies what messages each service can send and receive. To create a contract, use the following syntax: "CREATE CONTRACT [ContractName] ([MessageType] SENT BY ANY);"

  4. Create a Queue: Each Service Broker application requires at least one queue to store messages. To create a queue, you need to use this syntax: "CREATE QUEUE [QueueName];"

  5. Create a Service: A Service Broker service defines the endpoint for receiving messages. You create a service using the following syntax: "CREATE SERVICE [ServiceName] ON QUEUE [QueueName] ([ContractName]);"

  6. Start Sending Messages: Once you have created your Service Broker application, you can start sending messages between services using the SEND command.

Overall, is a multi-step process that involves defining message types, contracts, queues, and services. Once you have completed these steps, you can start sending messages between services using the SEND command.
