COMPLY WITH ORDER OF OPTIMISATION
In this case, the term stands for the basic administration of SAP systems. In this context, responsible employees perform a number of classic tasks.
An important area of SAP Security is the analysis of the customer's own SAP programs, which are classically written in the proprietary SAP language ABAP. Here, too, as in all programming languages, security vulnerabilities can be programmed - whether consciously or unconsciously. However, the patterns of security vulnerabilities in ABAP code differ from those in Java stacks or Windows programs. The goal of these conventional programs is usually to either crash the program (buffer overflow) or to artificially execute the program's own code (code injection). Both is not possible in ABAP, since a crash of a process causes nothing else than the creation of an entry in the log database (Dump ST22) and a subsequent termination of the report with return to the menu starting point. So a direct manipulation as in other high level languages or servers is not possible. However, there are other manipulation possibilities.
Call Inheritance Hierarchy
The core of SAP Basis is the application layer with one or more application servers and a message server. The message server is used for communication between the application servers and transmits jobs between them. The application layer communicates with the database layer on the one hand and the presentation layer on the other. The applications on the application server request the required data from the database, process it and prepare it for the user, who displays it in his Graphical User Interface (GUI) via the presentation layer. Conversely, the application server passes information that the user enters via the GUI on to the database.
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.
"Shortcut for SAP Systems" makes it easier and quicker to complete a number of SAP basis tasks.
Support Packages from SAPNet - Web Frontend or Collection CDs are available in a compressed format.
It is also possible to export the audit logs or add optional comments to the logs later.
