Layer Description
Technological basis for SAP Fiori (SAP Gateway)
In general, SAP operations and all associated activities need to be further professionalised. This includes the documentation of key and mission critical processes and their verification for timeliness and validity. It is also necessary to record and describe the performance of the base by IT service management, as well as techniques such as a RACI matrix to identify and document the responsibilities of the SAP basis.
Reduce resources: depending on the agreement of the contract, you can ask for the service resources only when needed. This will save you some costs.
ADMIN TOOLS
This is key to leveraging SAP's simplification plan. Since the release of SAP HANA, SAP has worked to simplify the system.
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.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
SAP Basis is therefore comparable to the server and platform infrastructure and its administration in companies - as distinct from application and web development.
On www.sap-corner.de you will also find useful information about SAP basis.
The presentation layer is based on the software components, collectively called "SAP GUI".
