PERFORMANCE TUNING
SU25 Profile generator: upgrade and initial installation
Instead of data maintenance and application development, SAP Basis is more about providing and maintaining the software environment on which the data resides and is processed. Therefore, SAP Basis is an important core of any SAP infrastructure and is required in both predecessor versions such as R/3 and current versions such as S/4HANA 2021.
Job scheduling: your system needs to run various automated background jobs that consume resources. Your administrator must carefully schedule these tasks when user demand is low so they don't impact performance.
Conceptual support for the architecture of system landscapes
The presentation layer is the top layer of the R/3 SAP Basis system and includes the communication with the user. Here, the data is graphically prepared for the user on the end device by means of software components from the application programs of the application layer. The presentation layer is the interface to the user (SAP GUI).
SAP Basis is responsible for the smooth operation of programs in the SAP system. It acts like an operating system for R/3 and subsequent releases including S/4HANA. Every operating system provides an environment in which programs can run, such as MS Office on Microsoft Windows. In the same way, the SAP Basis system with the NetWeaver and HANA platforms provides an environment in which SAP programs can run. In this context, the NetWeaver platform itself relies on server operating systems such as Windows and Linux.
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.
Site Reliability Engineering(SRE) is the equivalent of SAP Basis in the Google world.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
