5 Service Broker Overview 1 Uses for Service Broker 2 Service Broker Objects 3 Service Broker, ETL/Replication alternative 4 What We Will Focus On

6 What is Service Broker? ASYNCHRONOUS delivery and processing of messages Messages are delivered in order SQL Server uses Service Broker for Database Mail Core feature since SQL Server 2005 http://cache3.asset-cache.net/gc/490169030-holton-hill-of-the-texas-longhorns- gettyimages.jpg?v=1&c=IWSAsset&k=2&d=X7WJLa88Cweo9HktRLaNXrvtqse2XI3FUhrs kKSzGlkHkq6rv%2BIqaLWv5i%2BPim4TQeOQopxrdyKbnUopIhRGcw%3D%3D

7 Uses For Service Broker Asynchronous processing such as order fulfillment and credit card transactions Near real-time ETL Alternative to replication Data Sharding

8 Key Terminology/Components Message Types Contracts Queues Services Conversations Endpoints Routes

9 Message Types CREATE MESSAGE TYPE sb_MessageType_Longhorns_Roster AUTHORIZATION dbo VALIDATION= WELL_FORMED_XML Send Messages to/from databases on: The same instance Different instances, same server Different Servers https://www.google.com/search?q=texas+longhorns+football+2015+touchdown&espv=2&biw=160 0&bih=775&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjDw5yzx8jKAhUEHD4KHbozDYQQ_A UICCgD#tbm=isch&q=texas+longhorns+football+play+diagram&imgrc=ExKwCMMzRDQlHM%3A CREATE MESSAGE TYPE sb_MessageType_Longhorns_Plays_Processing AUTHORIZATION dbo VALIDATION= WELL_FORMED_XML

10 https://s-media-cache-ak0.pinimg.com/736x/9a/ed/e3/9aede387c65ed592e2ea11a3b30c6c44.jpg Contracts Once Message Types are defined, Contracts are created to determine who is allowed to send messages, and in which direction CREATE CONTRACT sb_contract_Longhorns_Plays_Processing AUTHORIZATION dbo ( sb_MessageType_Longhorns_Plays_Proces sing SENT BY ANY) GO

11 Queues Message storage until the message can be handled Possible to automatically activate a messaging handling system https://static-s.aa-cdn.net/img/ios/317787057/dda7d412fc6dbbdb65abc0ce6d3940d7?v=1 CREATE QUEUE sb_queue_Longhorns_Plays_Processing WITH STATUS= ON, RETENTION= OFF GO

12 Services CREATE SERVICE [sb_srvc_Longhorns_Alpha] AUTHORIZATION WR01_ALPHA_User ON QUEUE sb_queue_Longhorns_Alpha ([sb_contract_Longhorns_Sync]) GO Send messages to their queues or receive messages from other senders http://a.fssta.com/content/dam/fsdigital/fscom/ncaa-fb/images/2015/03/26/032615-NCAA-FB- Texas-Longhorns-Strong-SOMETHINGS-MISSING-PI-SW.vresize.1200.675.high.29.jpg

13 Conversations https://usatftw.files.wordpress.com/2015/08/xxx__longhorns_6370_7509 0712.jpg?w=1000&h=600&crop=1 This is the channel that the services send and receives messages from the queues BEGIN DIALOG CONVERSATION @conversation_handle FROM SERVICE @FromService TO SERVICE @ToService ON CONTRACT @Contract WITH ENCRYPTION= ON; SENDON CONVERSATION @conversation_handle MESSAGETYPE @MessageType(@MessageBody);

17 Endpoints A SQL Server endpoint is the TCP/IP point of entry into SQL Server. This is how the service broker dialogs are directed http://cnet1.cbsistatic.com/hub/i/r/2014/09/11/4fd0b9ca-10cc-46d8-a055- 4c5fec2e05f3/resize/970x546/e04b33c5881a7cf1ca11b6bee139a9a6/icups.jpg CREATE ENDPOINT WAREWOLF_ALPHA_Endpoint STATE= STARTED AS TCP ( LISTENER_PORT = 4022 ) FOR SERVICE_BROKER (AUTHENTICATION = WINDOWS ); GO GRANT CONNECT ON ENDPOINT::[WAREWOLF_ALPHA_Endpoint] to [SQLWAREWOLF-LAP\sqlwarewolf] GO

18 Routes This is how SQL Server knows where to send our message A route needs to be created in the database as well as MSDB CREATE ROUTE sb_route_Longhorns_Wolfpack AUTHORIZATION dbo WITH SERVICE_NAME = N'sb_srvc_Longhorns_Wolfpack', ADDRESS = N'TCP://localhost:4023' GO USE msdb; GO create ROUTE sb_route_Longhorns_Alpha AUTHORIZATION dbo WITH SERVICE_NAME = N'sb_srvc_Longhorns_Alpha', ADDRESS = N'LOCAL' GO

19 Remote Service Binding Creates a “partnership” between the Remote Service and the local service. Defines the security between the two http://interactives.dallasnews.com/2015/college-football-preview/images/TEXASlede.JPG USE TexasLonghorns GO CREATE REMOTE SERVICE BINDING [WR02_WOLFPACK_Binding] AUTHORIZATION dbo TO SERVICE N'sb_srvc_Longhorns_Wolfpack' WITH USER = [WR02_WOLFPACK_User] GO GRANT SEND ON SERVICE::[sb_srvc_Longhorns_Alpha] TO WR02_WOLFPACK_User;
