SAP Java requires 4 Systems Landscape Architecture while ABAP requires 3 Systems Landscape Architecture, Why ?

ABAP Stack require 3 System Landscape
ABAP requires 3 systems Landscape because ABAP modifies programs and moves them as a program to the consolidation for Testing. Since ABAP has both have Client Dependent and Client Independent data(s) and programs (cross client data consists of Programs and Data Dictionary), modification to such programs cannot be tested reliably in the same (development) system, which anyway would work correctly. So to simulate a production environment the changes need to be tested in Quality System. So an ABAP system would require 3 and not 2 systems landscape.

JAVA Stack require 4 System Landscape
In a Java stack the program are not moved alone, they are moved along with its other dependencies as a Software Component (jar, ear files). In the development system a user can copy the program and modify it and but would require a consolidation system for consolidating and building the application (Software Component). So a program is transported from Development System to Consolidation System. The Consolidation system will build the application. Once the software components are built they would be moved to Test System for Testing and finally to delivery System (Production System). Thus a Java Stack would require a 4 system landscape for a development Infrastructure.

In addition to these 4 Servers, there would be one more system which will host the Netweaver Development Infrastructure Application (NW + NWDI)

Development System -> Consolidation System -> Test System -> Productions System


Development : will have the modified Sources
Consolidation : Will consolidate the modified program from Development system and will be built as a Software component (jar File)
Testing : Software Component will tested here
Production : Productions System

Product -> Software Component -> Development Component -> Program

How to register CCMS Agent (SAPCCMSR) on JAVA stack for it to be monitored in the ABAP STACK?

How to connect SAP Java to CEN system on the ABAP Stack
Where Java Stacks ends the data to ABAP Stack to be monitored in the CEN CCMS system, while in NWA data from ABAP Stack and goes to the Java Stack, it is there in the NW2004s (NW7.0). The SAPCCMSR are installed and registered in the JAVA Stack, this agents pushes the data to the CEN or into the Solution Manager. This program reads the data from shared memory of the JAVA Stack, where the data is populated by the J2EE engine. It is similar to the program SAPCCM4X in ABAP Stack.

Tx Code RZ21
1. Creating CSMREG User

2. Creating start file for CSMCONF Agent

3. Register the Username and Password in Visual Administrator
For Dispatcher -> Services -> Monitoring

4. Then Click on the register button.

5. If Visual Administrator fails to register the gent, the manually do it by using command at the bottom of the below picture.

6. Then check in the ABAP Stack, Tx. Code RZ21 (J2ee -> Engines) the node will appear.
