Identification of specific transactions with user assignment
SAP ON AZURE OR AWS
In some cases, the term SAP Basis is also equated with the administration of an SAP system, i.e. with a task description. In this case, it refers to the management and control of SAP systems via various administration and monitoring tools.
Basis administrators often have basic ABAP knowledge, for example, and ABAP developers know the basics of SAP Basis. Nevertheless, the two fields of activity are usually organizationally separated in the company.
What does an SAP administrator need to be able to do?
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.
So-called Access Control Lists (ACL) offer a good possibility to secure your gateway in order to exclude unwanted external accesses to the database of the application server. With the help of the ACL files reginfo and secinfo an access control can be implemented, in which allowed as well as forbidden communication partners can be defined. The reginfo file controls the registration of external programs on the gateway, which means that rules can be defined that allow or prohibit programs. With the help of the file secinfo you can define which users are allowed to start an external program. To be able to use these files, you must set the parameters gw/reg_info and gw/sec_info (transaction RZ11). For more information, refer to SAP Note 1408081.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.

Another important example is the reading permission for TemSe objects.
These files are of course needed for an import into your own SAP system.
