Runtime - Integration Server - Pipeline Services

阅读更多

Pipeline Services

1. Messages received at the integration server are processed through a defined series of steps called Pipeline Services.

2. When a message is received at the IS, the message is examined and all valid configurations (as maintained in the Integration Directory) for that message are executed.

 

Pipeline Entry Point

Transaction SICF -> default_host -> sap -> xi -> engine

 

Pipeline Services Steps

1. Receiver Identiifiicatiion
Determine which system(s) should participate in an exchange with the incoming message.
2. Interface Determiinatiion
For each receiver system determine which interface(s) should receive a message.
3. Message Branch / Split
If multiple receivers are found, XI will instantiate a new message for each receiver.
4. Request Message Mapping
Call the mapping program to transform the message structure to the receiver format.
5. Outbound Biindiing
Bind a specific destination and protocol to the message.
6. Call Adapter
Send the transformed message to the adapter or proxy.
