XI has two engines that are ABAP engine called ABAP stack and JAVA engine calles JAVA stack.

Some components are executed in ABAP stack and some components are executed in JAVA stack.

ABAP stack -

---

> Only Integration Engine(IE) and Business Process Engine(BPE) are executed in the ABAP stack

JAVA stack -

---

> Remaining all(IR, ID, Adapter Engine, RTWB) are executed in the JAVA stack.

Hi,

The ABAP stack consists of the Integration Server which in turn contains your Integration Engine and Business Process Engine.

The J2EE stack contains the Adapter Engine and your IR and ID run on the J2EE engine.

Most of XI pipelines happens in the ABAP stack.

Have a look at the below link:

The XI Pipeline steps happen in ABAP stack. During this process the Operation mapping is called during Interface Determination and the mapping is executed. Now ESR is part of Java Stack then where does the mapping gets executed.In ABAP stack or Java Stack.

Hi,

XI is running on both ABAP and Java engine.

There are some components of XI which runs on

ABAP engine like Integration engine and Business process engine as they run on ABAP they are called as ABAP stack.

SLD, IR, ID, RWB, AE which runs in Java engine called as Java stack.
