Runtime - Integration Server - Pipeline Services-优快云博客

本文介绍了一个集成服务器如何通过一系列步骤处理接收到的消息。这些步骤包括确定接收者身份、选择接口、消息分发、请求映射、绑定出站及调用适配器等，最终将消息转换为适合接收方的格式。

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.
