Biz TalkMessaging Overview Biz TalkMessaging Overview Presentation Transcript

  •  
  • Introduction
    • Used in all BizTalk solutions
    • Components
      • Messages
      • Message Boxes (SQL Server databases)
      • Ports
      • Pipelines
      • Pipeline components
      • Adaptors
  • Messages
    • The lifeblood of BizTalk
    • Can be either XML (Most Common) or Binary
    • Can be tracked using HAT

  • Pipelines
    • Provide the ability to perform processing and validation on incoming or outgoing messages
    • Four out of the box pipelines are:
      • Xml Receive – Contains the XML disassembler
      • PassThru Receive – No processing occurs in this pipeline
      • XmlTransmit – Contains the XML assembler.
      • PassThru transmit – Same as receive but out bound

  • Receive Pipeline Stages
    • Decode
    • Disassemble
    • Validate
    • Resolve Party
  • Send Pipeline Stages
    • Pre-Assemble
    • Assemble
    • Encode
  • Subscription
    • Core principal of BizTalk
    • Once a message has been processed it needs to be routed
    • An orchestration or send port can “subscribe” to show it is interested in processing
    • Each message has context properties
    • The message type property is assigned by the XML disassembler
    • Subscription is based upon message type and various other context properties
    • You can have your own properties these are known as promoted properties
  • Message Box
    • After processing by the adaptor and pipeline the BizTalk message agent commits the message to the message box
    • All inbound and outbound messages stored
    • Orchestration execution, dehydration, rehydration and message tracking rely on this
  • Ports
    • Physical end points for sending and receiving messages
    • The selection of communication type defines how external systems communicate with BizTalk
    • For send ports the type defines how BizTalk communicates with other systems
  • Receive Ports
    • Used for getting messages into BizTalk
    • Have one or more receive locations
    • This means that the same port can have different communication methods
  • Send Ports
    • Used for sending messages from BizTalk
    • One to one relationship
    • Can use send port groups to send to multiple endpoints
