TADM10_2 SAP NetWeaver AS Implementation & Operation I
Technology Components for Browser-Based User Dialogs
Unit Overview
In this unit, you learn about a number of central technology components that are important if SAP systems are used for intranet or Internet applications. This course focuses on managing the components introduced here; development of these components is covered in other courses. The lesson entitled "Load Balancing in the SAP NetWeaver AS Java Environment" discusses some topics already covered in the previous lessons. Therefore, the main focus of this lesson is client-based load balancing.
- The SAP Internet Transaction Server (ITS) is used with Web applications (IACs) and with SAP GUI for HTML. Depending on the system release and scenario in question, the functions of the SAP ITS can be implemented by means of a standalone ITS or using the ITS integrated in the AS ABAP.
- The Internet Communication Manager (ICM) is the process that turns the conventional ABAP application server into a Web server or Web Client.
- The Internet Communication Framework (ICF) provides an environment for handling HTTP(S) requests in the ABAP work process using Web applications such as BSPs.
- With the usage type AS Java, the SAP NetWeaver Application Server provides a complete runtime environment for J2EE applications.
- SAP Web dispatcher distributes HTTP(S) requests to a suitable application server (instance).
Unit Objectives
After completing this unit, you will be able to:
- Describe the options that SAP provides for intranet and Internet scenarios
- Describe the areas of use of SAP ITS, ICM, AS ABAP, and AS Java
- Describe the architecture of the SAP ITS (standalone)
- Perform simple administrative tasks on an SAP ITS
- Describe the implementation area of the ICM
- Configure and monitor the ICM
- Explain the importance of the Internet Communication Framework (ICF) for handling HTTP requests in the SAP system
- Outline the interaction model
- Describe what constitutes an ICF service
- Activate and use the integrated ITS as of AS ABAP 6.40
- Outline the function of the SAP Web Dispatcher
- Explain how you can use the SAP Web Dispatcher to distribute workload across the different instances of an SAP system
- Explain how load balancing can be realized in the SAP system
