Installation
Technical and non-technical skills
SAP Basis or system administrators work with SAP Basis in a company. They are responsible for the correct installation, configuration and maintenance of the SAP application servers and applications, and in some companies also for the operating system and the SAP database if no administrators are available. Using SAP's own programming language ABAP, developers and programmers design SAP applications that run on the ABAP stack of the SAP NetWeaver Application Server as the only publicly accessible ABAP runtime environment. In some cases, the boundaries between ABAP developers and SAP Basis administrators are permeable, and each of the two groups of specialists has a basic knowledge of the other. As a rule, however, the competencies remain separate.
An understandable and comprehensible strategy enables the SAP basis to derive it as easily as possible to practice and to the resulting requirements and activities. The main task of the SAP basis is to support new business models by implementing the strategy and to show how much technical and financial effort and benefit is generated. It is also the task of the SAP basis to identify the skills and resources necessary for them and to ensure their existence at an early stage.
Migration to SAP HANA
In order to ensure the stability of the systems and to reduce the risk through proprietary developments, release and patch management must be implemented. Standardised procedures can help to introduce proprietary developments, such as test strategies or service level agreements (SLAs). It is also important to align the productivity setting of customer applications with the maintenance windows and RTO (Recovery-Time-Objective).
If the additional memory in the Advanced Storage Area is still not sufficient for the user context, the optional second role area can be used. The size of the second roll range is determined by the difference between the parameters ztta/roll_first and ztta/roll_area. Rolling range has been eliminated in kernel release 7.4, so these parameters are obsolete from then on. Instead, the user context is now stored directly in the Advanced Memory.
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.
They are therefore largely excluded from operational operations.
EARLY INVOLVEMENT IN THE PROJECT IS ESSENTIAL.
