CREATE OPEN SPACES
The presentation layer is based on the software components, collectively called "SAP GUI". This includes several possible implementation variants: for example, SAP GUI for HTML (Web GUI) and Web Dynpro for ABAP (WDA). Since the respective GUI depends entirely on the concrete application, the presentation layer looks very different in practice.
After your user has the necessary permissions for the SQL Editor, perform the following steps: Call the DBACOCKPIT transaction. Open the following folder structure in Database Administration: Performance -> Additional Functions -> SQL Command Editor Enter your first query in the input query. Then click Run or alternatively press F8 View of the DBA Cockpit Invoke the input query and drop the first SQL query View the results of a query to query the users of a system.
SUM - the Software Update Manager, the relatively new tool for "remote control" of the known update transactions from outside the system, for ABAP and JAVA
Basically, an SAP Basis administrator is responsible for installing, configuring, managing, maintaining and servicing all technical components of an SAP system landscape. This includes activities such as application setup, monitoring, and troubleshooting.
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" complement missing functions in the SAP basis area.
It is recommended to activate the cross-user logging with minimum settings and to record all audit classes for users with extensive authorizations, such as SAP standard and emergency users.
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.
This is also done with the tool "SUM" (Software Update Manager) via the so-called "DMO" (Database Migration Option).
