1 Performance Management of an SAP Solution
In this introductory chapter, we’ll present the architecture and the service concept for SAP solutions with regard to performance management.
Enterprises that implement SAP solutions expect them to be reliable and easy to maintain. In addition, SAP not only offers its tried-and-tested platform for SAP ERP and other business solutions with the most high-performance architecture on the market, but it also offers an innovative service concept.
In the first section, we’ll deal with the architecture in which SAP solutions are constructed and outline the potential for system optimization. At this stage, we deliberately dispense with technical details. In the second section, we deal with organizational questions regarding the running of an SAP solution, for example, the creation of a monitoring and optimizing plan. Two elements play key roles here: on one hand, you have a plan for the continuous monitoring of availability and performance of the business process and, on the other hand, you have the Service Level Management (SLM) method.
[»] When Should You Read This Chapter?
You should read this chapter if you want to develop a monitoring and optimization plan for an SAP solution. We recommend that you read this chapter first to get an overview of the contents of this book before getting into more detail in subsequent chapters.
1.1 SAP Solution Architecture
The architecture of SAP solutions is described in the following subsections. First, we’ll look at the different SAP solutions and components, followed by discussions of SAP HANA and the client/server architecture.
1.1.1 SAP Solutions and SAP Components
SAP provides integrated business software solutions for communication with customers (represented by SAP Customer Relationship Management [SAP CRM]), suppliers (SAP Supplier Relationship Management [SAP SRM]), and employees (SAP ERP Human Capital Management [SAP ERP HCM]), as well as solutions for logistics (SAP Supply Chain Management [SAP SCM]) and accounting and controlling (SAP ERP Financials [SAP ERP FI]). You can use these solutions to map the entire business, from marketing, sales, and service to invoicing, delivery, and collection to production and employee planning and the relevant processes of procurement, including the necessary accounting and controlling. Figure 1.1 shows the “disciplines” of business software and the relationships with the most important business partners: customers, employees, suppliers, and owners.
Figure 1.1 Structure of Business Software
The SAP solution portfolio provides different solutions for these business software disciplines. They are categorized by operating mode criteria—cloud or on premise—and enterprise size. However, describing the solution portfolio in detail would go beyond the scope of this introductory chapter.
To optimize your performance, you have to know which technologies are used to run the applications that are supposed to be optimized. Figure 1.2 and Figure 1.3 illustrate the traditional and future technology platform of SAP.
Figure 1.2 The Traditional SAP Technology Platform
When SAP R/3 was introduced, SAP software was built on a single technology component—SAP Basis. By contrast, SAP Business Suite is implemented on various technology components, which are shown in Figure 1.2 in detail:
- SAP NetWeaver Application Server ABAP (SAP NetWeaver AS ABAP) development and runtime environment (this is the successor to the SAP Basis that you know from SAP R/3 and contains the Development Workbench and the basic tools such as the Computing Center Management System [CCMS])
- SAP NetWeaver Application Server Java (SAP NetWeaver AS Java) development and runtime environment (formerly known as SAP J2EE Engine)
- Database and operating system platform
- SAP liveCache
- SAP Business Warehouse (SAP BW)
- SAP Process Integration (SAP PI)
- SAP Business Process Management (BPM)
- SAP Enterprise Portal
- SAP NetWeaver Enterprise Search with TREX
This list is by no means complete, but it’s intended to introduce the components presented in this book. You’ll find the complete component overview of SAP NetWeaver at www.sap.com/community/topic/netweaver.html.
The database is the medium used for permanently storing data. In addition to SAP’s own relational databases (SAP HANA, SAP MaxDB, SAP Adaptive Server Enterprise), SAP also supports the use of databases from other large producers (IBM, Oracle, Microsoft).
With SAP HANA, the concept of the technology platform as illustrated in Figure 1.3 changes significantly.
Figure 1.3 The Future SAP Technology Platform
With SAP S/4HANA and numerous applications specifically written for SAP HANA, SAP HANA is the exclusive database platform in which the functions of SAP TREX and SAP liveCache are natively integrated and for which the functions have been further enhanced. SAP NetWeaver AS ABAP (with the programming paradigm ABAP for SAP HANA) and SAP BW/4HANA actively support the SAP HANA technology. Of course, there are more components that contribute to this concept but aren’t mentioned here.
The next section further discusses the application scenarios for SAP HANA.
1.1.2 Application Scenarios for SAP HANA
SAP HANA can be used in the following application scenarios (see Figure 1.4):
- SAP Business Warehouse (SAP BW) on SAP HANA and SAP BW/4HANA
When using SAP HANA as your database for SAP BW, you can benefit from the performance advantages of SAP BW. SAP BW queries on InfoCubes and DataStore Objects (DSOs) are processed directly by the SAP HANA database; numerous administrative tasks for index and aggregate maintenance are no longer required. There is no need for a separate SAP...
