Integration Server(IS) It is the one of the component in the XI, it holds the Integration ingine, adapter engine

and Business process engine.

The communication b/w adapter engine and Integration engine is XI adapter

The communication b/w Business process engine and Integration engine is ABAP proxy.

Hi,

Integration Server

An integration server is a computer server used to facilitate interaction between diverse operating systems and applications across internal and external networked computer systems. An enterprise integration server may include prepackaged applications, customized applications, and legacy applications. Typically, an integration server has one of two architectures: the hub-and-spoke model or the network-centric bus model, also called the message-bus model.

In the hub-and-spoke model, all applications connect through a central server. The integration server manages all communication, data translation, and process interactions among the connected operating systems and applications. When a new operating system or application is connected, it is automatically integrated with all other systems. The hub-and-spoke model is better for companies with limited information technology (IT) resources with only a handful of systems handling a moderate volume of transactions.

Integration Engine

The Integration Engine enables you to process XML messages exchanged between applications in heterogeneous system landscapes. Both applications of SAP components and external applications can communicate with the Integration Engine.

Using adapters, the Integration Engine can also process IDocs (Intermediate Documents) and RFCs (Remote Function Calls). This option is available for applications that have already defined IDocs or RFCs, as well as for applications of SAP components that do not yet have access to the proxy generation functions.

The Integration Engine is the runtime environment of the SAP Exchange Infrastructure. The following are examples of other important parts of this infrastructure:

· Proxy Generation

· Integration Repository

· Integration Directory

The integration processes involved can take place between heterogeneous system components within a company, as well as between business partners outside company boundaries.

The Integration Engine, as a runtime component of SAP Exchange Infrastructure, has the task of receiving, processing, and forwarding XML messages. During message processing, collaboration agreements are evaluated, the receivers are determined, and mapping activities are executed.

The individual processing steps are called pipeline services and are defined in pipelines. It is the task of the Integration Engine to process these pipelines correctly and consistently. To guarantee this, you must configure the Integration Engine accordingly and monitor the message processing. Both event-driven message processing and prioritized message processing are possible.

HI

1.Integration server: It receives & forwards the messages of applications systems. It uses XML message format as it is easy to connect to non-sap systems. Once the data from non-sap system has been converted to xml using adapters, it is simple to convert data to other xml formats of other systems. Various engines work on integration server.

2.Integration Engine: Receives messages using Xi Message protocol and performs services like routing and mapping for received messages. XI Message protocol is based on w3c.SAP systems support this protocol directly using proxy runtime and local integration engine. So no adapters require communicating with integration engine.

Integration Server: This is the actual run time of XI. It is the central processing engine of the XI. All messages whether SAP or non-SAP, A2A or B2B, regardless of backend technology or vendor, are processed in a consistent way. It comprises of

u2022The Adapter Engine running on the JAVA stack and consisting of many JCA adapters.

u2022The Integration Engine running on the ABAP stack which process message in a consistent way using a series of pipeline steps.

u2022The Business Process Engine on the ABAP stack where the Integration process or BPM are executed.

Integration Engine: Runtime environment of the SAP XI that receives XML messages and after processing them in the pipeline transfers them to the receiver systems.

Integration Engine:

It s the place where message gets processed ie..message gets transformed from source format to target format...all the pipiline services will be executed here...

Integration server:

integration server resides at XI and takes care of all IE,AE,BPE

Thanks,

Hi,

The Integration Server is the central u2018distribution engineu2019 for messages in SAP Exchange Infrastructure at runtime. All systems that use SAP Exchange Infrastructure to communicate use this server to exchange messages. These systems are referred to as business systems at a logical level; within a specific system landscape they are called technical systems or communication parties. Using the configuration data from the Integration Directory, the Integration Server decides to which receiver or receivers it must send the message and whether a mapping needs to be executed beforehand.

The Integration Engine executes the integration logic of the Integration Server and converts messaging (of the Integration Server or application systems).

The Integration Engine enables you to process XML messages exchanged between applications in heterogeneous system landscapes. Both applications of SAP components and external applications can communicate with the Integration Engine.

Using adapters, the Integration Engine can also process IDocs (Intermediate Documents) and RFCs (Remote Function Calls). This option is available for applications that have already defined IDocs or RFCs, as well as for applications of SAP components that do not yet have access to the proxy generation functions.
