SM35 Batch input: session overview
Migration of an SAP system to other server landscapes
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.
The so-called SAP message server also belongs to the application layer. Only one instance of this server exists in the system. It mediates between the services and applications. In concrete terms, this means that the message server takes care of load balancing and determines, for example, on which application server a user logs on. Communication between application servers is also the domain of this message server.
Technical implementation and typical tools in the SAP Basis environment
With simple job programming, you can start in clear environments with few dependencies. If the number of jobs and the complexity increases, an automatic job control is a good choice. Honico Batchman is such a solution, a 100% SAP integrated AddOn, which is quickly and easily installed via normal transports. The advantage here is that no additional infrastructure is required; instead, the existing SAP system landscape is used for the entire control and execution without incurring a loss in performance. This also ensures full audit and operational security (compliance). Since pure SAP systems are rather the exception, non-SAP systems can also be controlled and monitored. As a third option, high-end solutions are available that additionally monitor the infrastructure and legacy. Widely used products in this segment are UC4 and Arvato Streamworks. These three solution options differ significantly in terms of price and scope of services. IT departments in companies must therefore evaluate which solution is best suited to their own requirements.
In the ERP environment, SAP has created a separate module for each business task area over the course of time. Companies have the option of putting together a suitable system from these modules, depending on their individual needs.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
Then switch to the Permissions tab to generate the current profile of the permission objects with the new Fiori permission.
SAP Basis refers to the administration of SAP system that includes activities like installation and configuration, load balancing, and performance of SAP applications running on Java stack and SAP ABAP. This includes the maintenance of different services related to database, operating system, application and web servers in SAP system landscape and stopping and starting the system. Here you can find some useful information about SAP Basis: www.sap-corner.de.
SAP Basis Operation is responsible for ensuring the technical functionality of an SAP system.
