SPAM Support Package Manager
Installation and configuration of SAP® systems
The SAP basis is often perceived as a brake within projects or when introducing new technologies. This is partly due to the late consultation of the SAP basis on the issues of technical feasibility as well as the integration of new technologies and applications into the existing system landscape. By implementing the recommendations, the SAP basis is repositioning itself in parts within the IT organisation. The SAP basis has a clearly defined self-understanding (inward-looking perception) as well as a clear positioning and a defined task area within the IT organisation (outward-facing perception), as shown in Figure 5. By integrating the SAP basis into the development of the IT strategy, the digitisation strategy and a clear communication with the CIO, the SAP basis has the opportunity to deal with technologies and topics at an early stage. As a result, the SAP basis is prepared for requests from business units or other IT departments and has the opportunity to approach them proactively. The SAP basis is supported by an IT service and IT product catalogue, which describes the scope of the SAP basis. For internal communication and communication with external service providers, as well as other suppliers, outsourcing partners or outsourcing partners and cloud service providers, there are up-to-date and meaningful documentation and process descriptions. For the control, measurement and monitoring of external partners, Service Level Agreements and meaningful key figures are also available.
Every SAP system architecture is as individual as the company itself. Full planning, including hardware sizing, is therefore essential. These services are included here:
Homogeneous
The Advanced Memory thus contains mainly user contexts of different work processes, if these cannot be loaded completely into the roll area. Since the storage area is accessible for all work processes, the work processes can also access external user contexts that lie here. In addition, the Advanced Memory contains a global area where data can be stored independently of user contexts. The extended memory size is determined by the values of em/initial_size_MB and em/global_area_MB. The first parameter determines the size of the storage area in which user contexts can be stored, and the second determines the size of the global area. Parameters for Private Storage Last but not least, there is the private storage, which is only used when the user context of a work process has used up all the other storage areas available to it, i.e. its share of the extended memory and its rolling area. In this case, the workprocess goes into PRIV mode. A workprocess in private mode is bound to its current user context and will not become free for other tasks until the current request is completed. If it has used up all the private memory allocated to it, the workprocess will then be restarted and the memory released. This behaviour is controlled with the abap/heaplimit parameter. At times, the user context may exceed the value of abap/heaplimit. The parameters abap/heap_area_total, abap/heap_area_dia and abap/heap_area_nondia define an upper limit for private storage. The abap/heap_area_total parameter defines how much private storage all workprocesses can use in total. The parameters abap/heap_area_dia and abap/heap_area_nondia, on the other hand, determine how much private storage a single (non-)dialogue workprocess can use.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page: "www.sap-corner.de".
In your applications, you better start to check them for risks early on and run this backup process regularly.
